Section 1 - Warranty

Warranty Registration: United States and Canada

To ensure that your warranty coverage begins promptly, your selling dealer should fill out the Warranty Registration Card completely and mail it to the factory immediately upon sale of the new product.

The Warranty Registration Card identifies the name and address of the original purchaser, product model and serial number(s), date of sale, type of use and selling dealer’s code, name, and address. The dealer also certifies that you are the original purchaser and user of the product. A temporary Owner Warranty Registration Card will be presented to you when you purchase the product.

Upon receipt of the Warranty Registration Card at the factory, Mercury MerCruiser will send you an owner resource guide that includes your warranty registration confirmation. If you do not receive your owner resource guide within 60 days from date of new product sale, please contact your selling dealer.

Because of your selling dealer’s ongoing interest in your satisfaction, the product should be returned to him for warranty service. The product warranty is not effective until the product is registered at the factory.

NOTE: Registration lists must be maintained by the factory and dealer on marine products sold in the United States in the event that a safety recall notification under the Federal Boat Safety Act is required.

You may change your address at any time, including at time of warranty claim, by calling Mercury MerCruiser or sending a letter or fax to Mercury MerCruiser’s warranty registration department with your name, old address, new address, and engine serial number. Your dealer can also process this change of information.

United States customers or dealers may contact: Mercury Marine Attn: Warranty Registration Department W6250 Pioneer Road P.O. Box 1939 Fond du Lac, WI 54936-1939 920-929-5054 Fax 920-929-5893

Canadian customers or dealers may contact: Mercury Marine Canada Limited 2395 Meadowpine Blvd. Mississauga, Canada, L5N 7W6 Fax 1-800-663-8334

Warranty Registration: Outside the United States and Canada

To ensure that your warranty coverage begins promptly, your selling dealer should fill out the warranty registration card completely and mail it to the distributor responsible for administering the warranty registration and claim program for your area.

The warranty registration card identifies your name and address, product model and serial numbers, date of sale, type of use, and the selling distributor’s and dealer’s code number, name, and address. The distributor or dealer also certifies that you are the original purchaser and user of the product. A copy of the warranty registration card, designated as the purchaser’s copy, MUST be given to you immediately after the card has been completely filled out by the selling distributor or dealer. This card represents your factory registration identification. Keep the card; if you ever need warranty service on this product, your dealer may ask you for the warranty registration card to verify date of purchase and to use the information on the card to prepare the warranty claim forms.

In some countries, the distributor will issue a permanent (plastic) warranty registration card to you within 30 days after receiving the factory copy of the warranty registration card from your distributor or dealer. If you receive a plastic warranty registration card, you may discard the purchaser’s copy that you received from the distributor or dealer when you purchased the product. Ask your distributor or dealer if this plastic card program applies to you. For further information concerning the warranty registration card and its relationship to warranty claim processing, refer to the International Warranty. See Table of Contents.

NOTE: Registration lists must be maintained by the factory and dealer on marine products sold in the United States in the event of a safety recall notification under the Federal Boat Safety Act.

Transfer of Warranty

The limited warranty is transferable to a subsequent purchaser, but only for the remainder of the unused portion of the limited warranty. This will not apply to products used for commercial applications.

To transfer the warranty to the subsequent owner, send or fax a copy of the bill of sale or purchase agreement, new owner’s name, address and engine serial number to Mercury Marine’s warranty registration department. In the United States mail to:

Warranty Period for Commercial Use

The warranty period begins on the date the product is first sold to a commercial‑use retail purchaser or the date on which the product is first put into service, whichever occurs first.

Commercial use is defined as any work‑related or employment‑related use of the product, or any use of the product that generates income for any part of the warranty period, even if the product is only occasionally used for such purposes. The repair or replacement of parts or the performance of service under this warranty does not extend the life of this warranty beyond its original expiration date.

Warranty coverage is terminated for used product obtained in any of the following ways:

• Repossession from a retail customer

• Purchase at auction

• Purchase from a salvage yard

• Purchase from an insurance company that obtained the product as a result of an insurance claim

Conditions That Must Be Met in Order to Obtain Warranty Coverage

Warranty coverage is available only to retail customers that purchase from a dealer authorized by Mercury Marine to distribute the product in the country in which the sale occurred, and then only after the pre‑delivery inspection process specified by Mercury Marine is completed and documented. Warranty coverage becomes available upon proper registration of the product by the authorized dealer. Inaccurate warranty registration information regarding recreational use or subsequent change of use from recreational to commercial (unless properly reregistered) may void the warranty at the sole discretion of Mercury Marine. Routine maintenance must be performed according to the maintenance schedule in the Operation, Maintenance & Warranty manual in order to obtain warranty coverage. Mercury Marine reserves the right to make any warranty coverage contingent upon proof of proper maintenance.

What Mercury Marine Will Do

Mercury Marine's sole and exclusive obligation under this warranty is limited to, at our option, repairing a defective part, replacing such part or parts with new or Mercury Marine certified remanufactured parts, or refunding the purchase price of the Mercury Marine product. Mercury Marine reserves the right to improve or modify products from time to time without assuming an obligation to modify products previously manufactured.

How to Obtain Warranty Coverage

The customer must provide Mercury Marine with a reasonable opportunity to repair and reasonable access to the product for warranty service. Warranty claims shall be made by delivering the product for inspection to a Mercury Marine dealer authorized to service the product. If the purchaser cannot deliver the product to such a dealer, written notice must be given to Mercury Marine. Mercury Marine will then arrange for the inspection and any covered repair. The purchaser in that case shall pay for all related transportation charges and travel time. If the service provided is not covered by this warranty, the purchaser shall pay for all related labor and material and any other expenses associated with that service. The purchaser shall not, unless requested by Mercury Marine, ship the product or parts of the product directly to Mercury Marine. Proof of registered ownership must be presented to the dealer at the time warranty service is requested in order to obtain coverage.

90-864197084 NOVEMBER 2008 Page 13

Page 22

Section 1 - Warranty

Mercury MerCruiser products installed by a Mercury Installation Quality Certified Manufacturer are Installation Quality certified products and may receive an additional one (1) year of limited warranty coverage.

The Installation Quality Certification program was developed to recognize MerCruiser boatbuilder customers who have achieved higher manufacturing standards. It is the first and only comprehensive manufacturer‑installation certification program in the industry.

The program has three goals:

1. To enhance overall product quality.

2. To improve the boat ownership experience.

3. To enhance overall customer satisfaction. The certification process is designed to review all facets of manufacturing and engine installation. The program is composed of

design, manufacturing and installation review stages with which builders must comply. Certification applies leading‑edge methodologies to create:

• Efficiencies and best practices specific to engine installation.

• World‑class assembly and component specifications.

• Efficient installation processes.

• Industry standard end‑of‑line test procedures

Boat builders that successfully complete the program and meet all certification requirements earn Installation Quality System Certified Manufacturer status and receive an additional one (1) year of Mercury limited factory warranty coverage on all MerCruiser‑powered boats that are registered on and after the boat builder's certification date for all worldwide registrations.

Mercury has designated a section of our Website to promote the Installation Quality Certification Program and communicate its benefits to consumers. For a current list of MerCruiser‑powered boat brands that have earned Installation Quality Certification, visit www.mercurymarine.com/mercruiser_warranty.

California Emissions Limited Warranty

NOTE: Mercury Marine does not establish model years for the Mercury MerCruiser product line. In order to comply with CARB warranty regulations, and for that limited purpose only, model year shall have the same meaning as calendar year. As an example, 2003 model year products refers to products manufactured during calendar year 2003.

The California Air Resources Board has promulgated air emissions regulations for inboard and sterndrive engines. The regulations apply to all inboard and sterndrive engines that were manufactured for the 2003 model year and later. Mercury Marine, in compliance with those regulations, provides this limited warranty for the emission control systems (see the components of the emission control system listed following), and further warrants that the inboard or sterndrive engine was designed, built, and equipped to conform with all applicable regulations adopted by the California Air Resources Board pursuant to its authority in Chapters 1 and 2, Part 5, Division 26 of the Health and Safety Code. For information regarding the limited warranty for the non‑emissions related components of the inboard or sterndrive engine, please see the limited warranty statement for your engine.

What Is Covered

NOTE: Your dealer will register your engine for warranty coverage for you. The warranty registration process is not related in any way to the process of obtaining a license, title or registration from state boating authorities. You should ask your dealer to update your warranty registration information to reflect a change of address or a transfer of ownership. (This change may be made at any time.) See the Warranty Registration section of your manual or your dealer for more information.

Mercury Marine warrants the components of the emissions control systems (see the components of the emission control system listed following) of its new, 2003 model year and later California certified inboard and sterndrive engines, registered to a California resident, to be free from defects in material or workmanship that cause the failure of a warranted part to be identical in all material respects to that part as described in the application of Mercury Marine for certification from the California Air Resources Board, for the period of time, and under the conditions identified below. The cost to diagnose a warranty failure is covered under the warranty (if the warranty claim is approved). Damage to other engine components caused by the failure of a warranted part will also be repaired under warranty.

Duration Of Coverage

Page 14 90-864197084 NOVEMBER 2008

Page 23

Section 1 - Warranty

This limited warranty provides coverage for the components of the emissions control systems of new 2003‑2008 model year inboard and sterndrive engines for 2 years from either the date the product is first sold, or first put into service, whichever occurs first. Emission related normal maintenance items such as spark plugs and filters, that are on the warranted parts list (see following) are warranted up to their first required replacement interval only. (See Maintenance Schedule). The repair or replacement of parts, or the performance of service under this warranty, does not extend the life of this warranty beyond its original expiration date. Unexpired warranty coverage can be transferred to a subsequent purchaser. (See instructions on transfer of warranty). Warranty coverage is terminated for used product repossessed from a retail customer, purchased at auction, from a salvage yard, or from an insurance company that obtained the product as a result of an insurance claim.

How To Obtain Warranty Coverage

The customer must provide Mercury with a reasonable opportunity to repair and reasonable access to the product for warranty service. Warranty claims shall be made by delivering the product for inspection to a Mercury dealer authorized to service the product. If purchaser cannot deliver the product to such a dealer, please notify Mercury Marine and Mercury will then arrange for the inspection and any covered repair. Purchaser in that case shall pay for all related transportation charges and/or travel time. If the service provided is not covered by this warranty, purchaser shall pay for all related labor and material, and any other expenses associated with that service. Purchaser shall not, unless requested by Mercury, ship the product or parts of the product directly to Mercury. Proof of registered ownership must be presented to the dealer at the time warranty service is requested in order to obtain coverage.

Features and Controls

Lanyard Stop Switch

The purpose of a lanyard stop switch is to turn off the engine when the operator moves outside the operator's position (as in accidental ejection from the operator's position).

RUN

a - Stop switch b - Lanyard c - Clips to the operator

74608

Accidental ejections, such as falling overboard, are more likely to occur in:

• low‑sided sport boats

• bass boats

• high performance boats

Accidental ejections can also occur from:

• poor operating practices

• sitting on the seat or gunwale at planing speeds

• standing at planing speeds

• operating at planing speeds in shallow or obstacle infested waters

• releasing your grip on the steering wheel that is pulling in one direction

• consuming alcohol or drugs

• high speed boating maneuvers

The lanyard is a cord usually between 122 and 152 cm (4 and 5 ft) in length when stretched out, with an element on one end made to be inserted into the switch and a snap on the other end for attaching to the operator. The lanyard is coiled to make its at‑rest condition as short as possible to minimize the likelihood of lanyard entanglement with nearby objects. Its stretched‑out length is made to minimize the likelihood of accidental activation should the operator choose to move around in an area close to the normal operator's position. If it is desired to have a shorter lanyard, wrap the lanyard around the operator's wrist or leg, or tie a knot in the lanyard.

Activation of the lanyard stop switch will stop the engine immediately, but the boat will continue to coast for some distance depending upon the velocity and degree of any turn at shut down. However, the boat will not complete a full circle. While the boat is coasting, it can cause injury to anyone in the boat's path as seriously as the boat would when under power.

We strongly recommend that other occupants be instructed on proper starting and operating procedures should they be required to operate the engine in an emergency (e.g. if the operator is accidentally ejected).

WARNING

If the operator falls out of the boat, stop the engine immediately to reduce the possibility of serious injury or death from being struck by the boat. Always properly connect the operator to the stop switch using a lanyard.

Accidental or unintended activation of the switch during normal operation is also a possibility. This could cause any, or all, of the following potentially hazardous situations:

• Occupants could be thrown forward due to unexpected loss of forward motion, a particular concern for passengers in the front of the boat who could be ejected over the bow and possibly struck by the propulsion or steering components.

• Loss of power and directional control in heavy seas, strong current or high winds.

• Loss of control when docking.

WARNING

Avoid serious injury or death from deceleration forces resulting from accidental or unintended stop switch activation. The boat operator should never leave the operator's station without first disconnecting the stop switch lanyard from the operator.

Emergency Stop (E‑Stop) Switch

The emergency stop (E‑stop) switch turns off the engines in an emergency situation, such as a person overboard or tangled propeller. When activated, the E‑stop switch interrupts the power supply to the main power relay, including power to the gauges, steering, and accessories.

Activation of the E‑stop switch stops the engines immediately, but the boat continues to coast for some distance depending upon the velocity and degree of any turn at shutdown. However, the boat does not complete a full circle. While the boat is coasting, it can cause injury to anyone in the boat's path as seriously as the boat would when under power.

We recommend instructing other occupants on proper starting and operating procedures should they need to operate the engine in an emergency.

Accidental or unintended activation of the switch during normal operation is also possible, which can cause any or all of the following potentially hazardous situations:

• Occupants can be thrown forward due to unexpected loss of forward motion, a particular concern for passengers in the front of the boat who could be ejected over the bow and possibly struck by the propulsion or steering components.

• Operator can lose power and directional control in heavy seas, strong current, or high winds.

• Operator can lose control when docking.

Instrumentation

VesselView (If Equipped)

The SmartCraft VesselView is the recommended information source for all drive information, engine information, fault codes, vessel information, basic navigation data, and system information.

Electronic Helm Steering

The electronic helm steering operates through electronic signals. A computer‑controlled electric motor simulates the resistance feedback found in hydraulic steering systems.

We recommend that you drive carefully until you have a chance to explore the Axius system's handling characteristics and boat's responses in an open area clear of obstructions or other boat traffic. The initial steering setting of two turns lock‑to‑lock provids a fast steering response. Maneuvers at speed can be more abrupt than expected. The distributor can adjust the number of turns, if desired.

Dual‑Handle Electronic Remote Control (ERC) with DTS Trackpad Features and Operation

Operation

The electronic remote control (ERC) handle operates the shift and throttle. Push the ERC handles handle forward from neutral to the first detent for forward gear. Continue pushing the ERC handle forward to increase speed. Pull the ERC handle from the forward position to the neutral position to decrease speed and eventually stop. Pull the ERC handle back from neutral to the first detent for reverse gear. Continue pulling the handle back to increase speed.

Page 26 90-864197084 NOVEMBER 2008

Page 35

Section 2 - Getting to Know Your Power Package

NOTE: When using the joystick, the computer moves the sterndrive in and out of gear even though the ERC handles remain in neutral.

Typical ERC handles

a - Neutral b - Forward c - Reverse d - Bow of boat

28086

Adjustment

The amount of force needed to move the ERC handles and to move the ERC handles through the detentes is adjustable to help prevent unwanted motion of the handle in rough water.

To adjust ERC handle tension:

1. Remove the port side cover for port lever adjustment, and starboard side cover for starboard lever adjustment.

2. Turn the screw clockwise to increase tension on the control handle and counter‑clockwise to decrease tension.

3. Adjust to tension desired. To adjust ERC handle detent tension:

1. Remove the port side cover for port lever adjustment, and starboard side cover for starboard lever adjustment.

2. Turn the screw clockwise to increase tension on the control handle and counter‑clockwise to decrease tension.

3. Adjust to desired tension.

Joystick—Basic Operation

The joystick offers precise, intuitive control of your boat during low speed and docking maneuvers. Engine speed is limited in this mode to prevent excessive prop wash or unacceptable boat dynamics during maneuvers.

Though joystick operation is easy and intuititve, you should avoid using it until you have the opportunity to become familiar with the joystick in open water. Thereafter, you should occaisionallly practice operating without the joystick in case the joystick becomes inoperable.

Power Trim

Power trim allows the operator to adjust the sterndrive angle while underway to achieve the ideal boat angle for varying load and water conditions. The trailering feature allows the operator to raise and lower the sterndrive unit for trailering, beaching, launching, low speed (below 1200 rpm), and shallow water operation.

90-864197084 NOVEMBER 2008 Page 27

Page 36

Section 2 - Getting to Know Your Power Package

ERC Trim Control

WARNING

Excessive trim can cause serious injury or death at high speeds. Use caution when trimming the sterndrive, and never trim out beyond the gimbal ring support flanges while the boat is underway or at engine speeds above 1200 RPM.

Some ERC's will have a single button for trimming both sterndrives simultaneously or may have separate buttons for each sterndrive unit.

For best performance trim the sterndrive unit so that the boat bottom is at a 3‑5° angle to the water.

3 - 5

mc79528

Trimming the sterndrive unit up (out) can:

• Generally increase top speed

• Increase clearance over submerged objects or a shallow bottom

• Cause the boat to accelerate and plane off slower

• In excess, cause boat porpoising (bouncing) or propeller ventilation

• Cause engine overheating, if trimmed up (out) to a point where any cooling water intake holes are above the water line

mc78529

Trimming the sterndrive unit down(in) can:

• Causes the boat to accelerate and plane off quicker

• Generally improve the ride in choppy water

• In most cases, reduce boat speed

• In excess, can cause bow steering (unexpected turning) by lowering the bow of the boat so that it plows the waterline while on plane.

mc79530

Page 28 90-864197084 NOVEMBER 2008

Page 37

Section 2 - Getting to Know Your Power Package

Joystick and Trim Control

24704

Typical joystick

While using the Axius joystick, the best boat control is achieved when the sterndrives are in the full down (in) position. Full down (in) trim maximizes propeller efficiency allowing the boat to move parallel with the joystick command. The joystick will function while the sterndrives are trimmed up (out), however control of the boat may be limited or altered because the inefficiency of the propellers at or near the top of the water surface.

Trailer and Trailer Limit Position

On digital throttle and shift controls, the trim button (if equipped) also functiones as a trailer button that trims the sterndrives to a limited up (out) position suitable for trailering purposes only. Based upon engine RPM, the system limits the amount of trim up (out) and the availabilty of trailer position. The trailer limit function is designed to prevent damage to swim platforms.

Depending on the type of control or panel, the trailer position includes a single integral button to operate both sterndrive units simultaneously or separate buttons for each sterndrive unit.

Trim without Key

CAUTION

The Trim Without Key mode allows trim operation after the ignition key switch is turned off. To avoid injury or product damage, do not attempt any engine‑ or sterndrive‑related repairs or maintenance until performing the Wide Open Throttle Reverse operation to end the Trim Without Key mode.

Trim without key is a method of allowing trim operation after the ignition key switch is turned off. The command module and PCM remain powered and process trim requests for up to 15 minutes after the key switch is turned off. The command module does not process any requests other than trim during this period. Once the 15 minute period expires, the command module sends a command through the CAN lines to shut down the PCM. On multi‑engine applications, the time‑out is managed separately for each engine.

The trim without key period may be ended at any time by moving the control handle to Wide Open Throttle Reverse (WOTR) with the key off. To end the 15 minute period for the center engine in a shadow mode application, ensure all ignition key switches are in the "OFF" position and both remote control handles are in the Wide Open Throttle Reverse (WOTR) position.

Electrical System Overload Protection

If an electrical overload occurs, a fuse will blow or the circuit breaker will trip open. You must find and correct the cause before replacing the fuse or resetting the circuit breaker.

NOTE: In an emergency, when the engine must be operated and the cause for the high current draw (overload) cannot be located and corrected, turn off or disconnect all accessories connected to the engine and instrumentation wiring. Reset the circuit breaker. If the breaker remains open, the electrical overload has not been eliminated. Further checks must be made on the electrical system. Contact your authorized dealer.

Warning Horn Signals

Most faults will cause the warning horn circuit to activate. How the warning horn activates depends on how serious the problem is. There are four warning horn states:

• Caution ‑ horn signal varies with product line and calibration. Minimal guardian.

• Warning ‑ horn signal varies with product line and calibration.

• Severe ‑ horn is beeping constantly.

• Critical ‑ horn is beeping constantly and guardian will be at forced idle.

In addition, depending on the gauge package, there will be warning icons and fault messages on the dash mounted gauges.

90-864197084 NOVEMBER 2008 Page 31

Page 40

Section 2 - Getting to Know Your Power Package

Audio Warning System

Your Mercury MerCruiser power package may be equipped with an Audio Warning System. The Audio Warning System will not protect the engine from damage. It is designed to warn the operator that a problem has occurred.

The audio warning system will sound with a continuous horn:

• Engine oil pressure is too low

• Engine temperature is too hot

• Seawater pressure is too low

The audio warning system will sound with an intermittent beeping:

• The sterndrive oil level is too low

• Engine guardian activates

• A sensor failure is detected

• A communication failure within a CAN system occurs

NOTICE

A continuous horn indicates a critical fault. Operating the engine during a critical fault can damage components. If the warning horn emits a continuous beep, do not operate the engine unless avoiding a hazardous situation.

If the alarm sounds, stop the engine immediately. Investigate the cause and correct it, if possible. If you cannot determine the cause, contact your authorized Mercury MerCruiser dealer.

Testing The Audio Warning System

1. Turn the ignition switch to the "ON" position without cranking the engine.

2. Listen for the audio alarm. One short beep will sound for each engine upon key‑up, indicating the system is functioning correctly.

Engine Guardian Strategy

IMPORTANT: Boat speed could be reduced to idle and may not respond to the throttle. Engine Guardian Strategy is designed to help reduce the potential for engine damage by reducing engine power when a potential

problem is sensed by the ECM. Engine Guardian monitors:

• Oil pressure

• Coolant temperature

• Seawater pressure

• Engine overspeed

• Exhaust Manifold Temperature [8.1 liter (496 cid) engines only]

Also the Engine Guardian Strategy will reduce engine power to 90 percent of maximum if any sensor on the power package fails. For example, if the water inlet becomes partially blocked, Engine Guardian Strategy will reduce the available power level of the

engine to help prevent damage from decreased water flow to the engine. If the debris passes through and full water flow is restored, engine power levels are restored to normal.

To avoid a possible recurrence of the problem you should contact an authorized dealer. The ECM stores the fault and with this information the technician will be able to more rapidly diagnose problems.

Section 3 - On The Water

Safe Boating Suggestions

To enjoy the water safely, you should know and understand all boating regulations and restrictions that pertain to your activity. Know and obey all nautical rules and laws of the waterways. Boat operators should complete a boating safety course. In the US, courses are offered by:

• The US Coast Guard Auxiliary

• The Power Squadron

• The Red Cross

• Your state or provincial boating law enforcement agency

Direct all inquiries to the Boat U.S. Foundation at 1‑800‑336‑BOAT (2628), or the US Coast Guard at 1‑202‑372‑1067. Additional information about boating education and safe boating practices is available on the following web sites:

• US Coast Guard Boating Safety Web Site: http://www.uscgboating.org/

• US Coast Guard Auxiliary: http://nws.cgaux.org/

• US Power Squadrons: http://www.usps.org

• Boat US: http://www.boatus.com

Perform safety checks and required maintenance.

Follow a regular schedule and ensure that all repairs are properly made.

Check for onboard safety equipment.

We suggest the following:

• Approved fire extinguishers

• Signal devices (flashlight, rockets or flares, flag, and a whistle or horn)

• Spare operating equipment (batteries, bulbs, fuses, etc.)

• Tools necessary for minor repairs

• An anchor and extra anchor line

• A manual bilge pump and extra drain plugs

• A supply of drinking water

• A transistor radio.

• Paddles or oars

• A spare propeller, spare thrust hubs, and an appropriate wrench

• A first aid kit and first aid instructions

• Waterproof storage containers

• A compass and appropriate maps or charts

Watch for signs of weather change.

Avoid foul weather and rough‑sea boating.

Tell someone where you are going and when you expect to return. Board cautiously.

Stop the engine whenever passengers are boarding, unloading, or are near the rear of the boat. Operating in neutral is not sufficient.

Train emergency boat operators.

Instruct at least one other person onboard in the basics of starting and operating the power package and boat handling in case the driver becomes disabled or falls overboard.

Do not overload your boat.

Most boats are rated and certified for a maximum load capacity. Know your boat’s loading limitations (refer to the boat capacity plate). If in doubt, contact your dealer or the boat's manufacturer.

Never boat under the influence of alcohol or drugs.

It is illegal to operate a boat under the influence of drugs or alcohol. Alcohol or drug use will impair your judgment and drastically reduce your ability to react quickly.

Make sure that everyone in the boat is properly seated.

Do not allow anyone to sit or ride inappropriately on any part of the boat. Inappropriate riding locations include seatbacks, gunwales, the transom, the bow, decks, raised fishing seats, any rotating fishing seat, or anywhere that sudden acceleration, stopping, loss of boat control, or other movement could throw a person into the boat or overboard.

Wear a personal flotation device (PFD) at all times while in the boat.

Page 36 90-864197084 NOVEMBER 2008

Page 45

Section 3 - On The Water

Federal law requires an approved personal flotation device for every person aboard, as well as a throwable cushion or ring. Flotation devices must fit correctly and be readily accessible.

Know your boating area and avoid hazardous locations. Be alert. By law, boat operators are responsible for ensuring that they can see or hear indications of danger. In particular, the operator’s

forward view should not be obstructed by passengers, cargo, or removable seats. Be aware of others, the water, and your wake.

Never follow a water skier.

Your boat will quickly overtake a fallen skier. If a skier falls, a boat following 61 m (200 ft) behind at 40 km/h (25 mph) will overtake the skier in five seconds.

Watch fallen skiers.

Never back up to anyone, including skiers, in the water. The operator should always keep the skier in sight, and on the operator's side of the boat while returning to assist the skier.

Report accidents.

Boat operators are required by law to file a Boating Accident Report with their state boating law enforcement agency when their boat is involved in certain boating accidents.

A boating accident must be reported if there is:

• Apparent or probable loss of life.

• Personal injury requiring medical treatment beyond first aid.

• Damage to boats or other property where the damage value exceeds $500.00.

• A complete loss of the boat.

IMPORTANT: Consult local law enforcement for a complete explanation of rules and regulations.

Be Alert to Carbon Monoxide Poisoning

Carbon monoxide is present in the exhaust fumes of all internal combustion engines including the outboards, sterndrives and inboard engines that propel boats, as well as the generators that power various boat accessories. Carbon monoxide is a deadly gas that is odorless, colorless and tasteless.

Early symptoms of carbon monoxide poisoning, which should not be confused with seasickness or intoxication, include headache, dizziness, drowsiness and nausea.

WARNING

Carbon monoxide poisoning can lead to unconsciousness, brain damage, or death. Keep the boat well ventilated while at rest or underway and avoid prolonged exposure to carbon monoxide.

Good Ventilation

Ventilate the passenger area, open the side curtains or forward hatches to remove fumes.

1. Example of desired air flow through the boat.

mc79553-1

Poor Ventilation

Under certain conditions, permanently enclosed or canvas enclosed cabins or cockpits with insufficient ventilation may draw in carbon monoxide. Install one or more carbon monoxide detectors in your boat.

Although the occurrence is rare, on a very calm day, swimmers and passengers in an open area of a stationary boat that contains or is near an operating engine may be exposed to a hazardous level of carbon monoxide.

1. Examples of poor ventilation while a boat is stationary:

Operating the engine when

a -

the boat is moored in a confined space

mc79554-1

b - Mooring close to another boat

with its engine operating

90-864197084 NOVEMBER 2008 Page 37

Page 46

Section 3 - On The Water

21604

2. Examples of poor ventilation while a boat is moving:

a - Operating the boat with the trim

angle of the bow too high

mc79556-1

b - Operating the boat with no

forward hatches open (station wagon effect)

Basic Boat Operation

Drain Plug and Bilge Pump

The engine compartment in your boat is a natural place for water to collect. For this reason, boats are normally equipped with a drain plug and/or a bilge pump. It is very important to check these items on a regular basis to ensure that the water level does not come into contact with your power package. Components on your engine will be damaged if submerged. Damage caused by submersion is not covered by the Mercury MerCruiser Limited Warranty.

Freezing Temperature Operation

IMPORTANT: If the boat is operated during periods of freezing temperature, precautions must be taken to prevent freeze damage to the power package. Damage caused by freezing is not covered by Mercury MerCruiser Limited Warranty.

Protecting People in the Water

While You Are Cruising

It is very difficult for a person in the water to take quick action to avoid a boat heading in their direction, even at slow speeds.

Always slow down and exercise extreme caution any time you are boating in an area where there might be people in the water. Whenever a boat is moving (even coasting) and the gear shift is in neutral, there is sufficient force by the water on the propeller

to cause the propeller to rotate. This neutral propeller rotation can cause serious injury.

While Boat Is Stationary

WARNING

A spinning propeller, a moving boat, or any solid device attached to the boat can cause serious injury or death to swimmers. Stop the engine immediately whenever anyone in the water is near your boat.

Shift into neutral and shut off the engine before allowing people to swim or be in the water near your boat.

High‑Speed and High‑Performance Operation

If your boat is considered a high‑speed or high‑performance boat with which you are unfamiliar, we recommend that you never operate it at its high speed capability without first requesting an initial orientation and demonstration ride with your dealer or an operator experienced with your boat. For additional information, refer to Hi-Performance Boat Operation booklet (90‑849250‑R2) from your dealer, distributor or Mercury Marine.

Passenger Safety in Pontoon Boats and Deck Boats

Whenever the boat is in motion, observe the location of all passengers. Do not allow any passengers to stand or use seats other than those designated for traveling faster than idle speed. A sudden reduction in boat speed, such as plunging into a large wave or wake, a sudden throttle reduction, or a sharp change of boat direction, could throw them over the front of boat. Falling over the front of the boat between the two pontoons will position them to be run over.

Boats Having An Open Front Deck

No one should ever be on the deck in front of the fence while the boat is in motion. Keep all passengers behind the front fence or enclosure.

Page 38 90-864197084 NOVEMBER 2008

Page 47

Section 3 - On The Water

Persons on the front deck could easily be thrown overboard or persons dangling their feet over the front edge could get their legs caught by a wave and pulled into the water.

mc79555-1

WARNING

Sitting or standing in an area of the boat not designed for passengers at speeds above idle can cause serious injury or death. Stay back from the front end of deck boats or raised platforms and remain seated while the boat is in motion.

Boats With Front-Mounted, Raised Pedestal Fishing Seats

Elevated fishing seats are not intended for use when the boat is traveling faster than idle or trolling speed. Sit only in seats designated for traveling at faster speeds.

Any unexpected, sudden reduction in boat speed could result in the elevated passenger falling over the front of the boat.

mc79557-1

Wave and Wake Jumping

WARNING

Wave or wake jumping can cause serious injury or death from occupants being thrown within or out of the boat. Avoid wave or wake jumping whenever possible.

mc79680-1

Operating recreational boats over waves and wakes is a natural part of boating. However, when this activity is done with enough speed to force the boat hull partially or completely out of the water, certain hazards arise, particularly when the boat re‑enters the water.

The primary concern is the boat changing direction while in the midst of the jump. In such cases the landing may cause the boat to violently veer in a new direction. Such a sharp change in direction or turn can cause occupants to be thrown out of their seats or out of the boat.

There is another less common hazardous result from allowing your boat to launch off of a wave or wake. If the bow of your boat pitches down far enough while airborne, upon water contact it may penetrate under the water surface and submarine for an instant. This will bring the boat nearly to a stop in an instant and can send the occupants flying forward. The boat may also veer sharply to one side.

90-864197084 NOVEMBER 2008 Page 39

Page 48

Section 3 - On The Water

Impact with Underwater Hazards

Reduce speed and proceed with caution whenever you're driving a boat in shallow water or in areas where the waters are suspected of having underwater obstacles that could be struck by the underwater drive components, rudder or the boat bottom.

mc79679-1

IMPORTANT: The most important thing you can do to help reduce injury or impact damage from striking a floating or underwater object is control the boat speed. Under these conditions, boat speed should be kept to a maximum speed of 24 to 40 km/h (15 to 25 mph).

Striking a floating/underwater object may result in an infinite number of situations. Some of these situations could result in the following:

• The boat could move suddenly in a new direction. Such a sharp change in direction or turn can cause occupants to be thrown out of their seats or out of the boat.

• A rapid reduction in speed. This will cause occupants to be thrown forward, even out of the boat.

• Impact damage to the underwater drive components, rudder and/or boat.

Keep in mind, one of the most important things you can do to help reduce injury or impact damage in these situations is control the boat speed. Boat speed should be kept to a minimum planing speed when driving in waters known to have underwater obstacles.

After striking a submerged object, stop the engine as soon as possible and inspect the drive system for any broken or loose parts. If damage is present or suspected, the power package should be taken to an authorized Mercury MerCruiser dealer for a thorough inspection and necessary repair.

The boat should be checked for hull fractures, transom fractures and water leaks. Operating with damaged underwater drive components, rudder or boat bottom could cause additional damage to other parts of

the power package, or could affect control of the boat. If continued operation is necessary, do so at greatly reduced speeds.

WARNING

Operating a boat or engine with impact damage can result in product damage, serious injury, or death. If the vessel experiences any form of impact, have an authorized Mercury Marine dealer inspect and repair the vessel or power package.

Drive Unit Impact Protection

The power trim hydraulic system is designed to provide impact protection for the sterndrive unit. If a submerged object is struck while the boat is moving forward, the hydraulic system will cushion the kickup of the sterndrive unit as it clears the object, reducing damage to the unit. After the sterndrive unit has cleared the object, the hydraulic system allows the sterndrive unit to return to its original operating position, preventing loss of steering control and engine overspeed.

Use extreme caution when operating in shallow water or where underwater objects are known to be present. No impact protection is provided in reverse; use extreme care to prevent striking submerged objects while operating in reverse.

IMPORTANT: Impact protection system cannot be designed to ensure total protection from impact damage under all conditions.

Trailering the Boat

IMPORTANT: The Axius system can not steer without the engines running. If your vessel requires a specific steering angle upon trailering, obtain that angle prior to keying down the engines.

The boat can be trailered with the sterndrive unit in the up(out) or down(in) position. Ensure adequate clearance between the road and sterndrive when transporting. If you require additional clearance, place the sterndrive unit in full trailer position and support it with an optional trailer kit, which is available from your authorized Mercury MerCruiser dealer.

Conditions Affecting Operation

Weight Distribution (Passengers and Gear) Inside the Boat

Shifting weight to rear (stern):

• Generally increases speed and engine RPM

Page 40 90-864197084 NOVEMBER 2008

Page 49

Section 3 - On The Water

• Causes bow to bounce in choppy water

• Increases danger of following wave splashing into the boat when coming off plane

• At extremes, can cause the boat to porpoise

Shifting weight to front (bow):

• Improves ease of planing

• Improves rough water ride

• At extremes, can cause the boat to veer back and forth (bow steer)

The Bottom of the Boat

To maintain maximum speed, the boat bottom should be:

• Clean, free of barnacles and marine growth

• Free of distortion; nearly flat where it contacts the water

• Straight and smooth, fore and aft

Marine vegetation may accumulate when the boat is docked. This growth must be removed before operation; it may clog the water inlets and cause the engine to overheat.

Cavitation

Cavitation occurs when water flow cannot follow the contour of a fast‑moving underwater object, such as a gear housing or a propeller. Cavitation increases propeller speed while reducing boat speed. Cavitation can seriously erode the surface of the gear housing or the propeller. Common causes of cavitation are:

• Weeds or other debris snagged on the propeller

• Bent propeller blade

• Raised burrs or sharp edges on the propeller

Ventilation

Ventilation is caused by surface air or exhaust gases that are introduced around the propeller resulting in propeller speed‑up and a reduction in boat speed. Air bubbles strike the propeller blade and cause erosion of the blade surface. If allowed to continue, eventual blade failure (breakage) will occur. Excessive ventilation is usually caused by:

• Drive unit trimmed out too far

• A missing propeller diffuser ring

• A damaged propeller or gear housing, which allows exhaust gases to escape between propeller and gear housing

• Drive unit installed too high on transom

Elevation and Climate

Elevation and climate changes will affect the performance of your power package. Loss of performance can be caused by:

• Higher elevations

• Higher temperatures

• Low barometric pressures

• High humidity

For you to have optimum engine performance under changing weather conditions, it is essential that the engine be propped to allow the engine to operate at or near the top end of the specified maximum RPM range with a normal boat load during your normal boating weather conditions.

In most cases, recommended RPM can be achieved by changing to a lower pitch propeller.

Propeller Selection

IMPORTANT: The engines covered in this manual are equipped with an RPM rev‑limiter that is set to an upper RPM limit. This limit, which is slightly above the normal operating range of the engine, helps prevent damage from excessive engine RPM. Once the RPM returns to the recommended operating RPM range, normal engine operation resumes.

The boat manufacturer and the selling dealer are responsible for equipping the power package with the correct propeller. Refer to Mercury Marine's web page http://www.mercurymarine.com/everything_you_need_to_know_about_propellers6.

Select a propeller that will allow the engine power package to operate at or near the top end of the recommended WOT operating RPM range with a normal load.

If full‑throttle operation is below the recommended range, the propeller must be changed to prevent loss of performance and possible engine damage. On the other hand, operating an engine above the recommended operating RPM range will cause higher than normal wear and damage.

After initial propeller selection, the following common problems may require that the propeller be changed to a lower pitch.

90-864197084 NOVEMBER 2008 Page 41

Page 50

Section 3 - On The Water

• Warmer weather and greater humidity cause a loss of RPM.

• Operating in a higher elevation causes a loss of RPM.

• Operating with a dirty boat bottom causes a loss of RPM.

• Operating with increased load (additional passengers, pulling skiers) causes a loss of RPM.

For better acceleration, such as is needed for water skiing, use the next lower pitch propeller. When not pulling skiers, do not operate at full throttle when using the lower pitch propeller.

Getting Started

20‑Hour Break‑In Period

IMPORTANT: The first 20 hours of operation is the engine break‑in period. Correct break‑in is essential to obtain minimum oil consumption and maximum engine performance. During this break‑in period, the following rules must be observed:

• Do not operate below 1500 RPM for extended periods of time for the first 10 hours. Shift into gear as soon as possible after starting and advance the throttle above 1500 rpm if conditions permit safe operation.

• Do not operate at one speed consistently for extended periods.

• Do not exceed 3/4 throttle during the first 10 hours. During the next 10 hours, occasional operation at full throttle is permissible (5 minutes at a time maximum).

• Avoid full throttle acceleration from idle speed.

• Do not operate at full throttle until the engine reaches normal operating temperature.

• Frequently check engine oil level. Add oil as needed. It is normal for oil consumption to be high during the break‑in period.

Launching and Boat Operation

IMPORTANT: Install bilge drain plug prior to launching boat.

NOTE: Perform only those functions applicable to your power package.

Starting the Engine

1. Check all items listed in the Operation Chart.

Page 42 90-864197084 NOVEMBER 2008

Page 51

Section 3 - On The Water

2. Place the remote control handle in neutral.

NOTICE

Without sufficient cooling water, the engine, the water pump, and other components will overheat and suffer damage. Provide a sufficient supply of water to the water inlets during operation.

WARNING

Explosive fumes contained in the engine compartment can cause serious injury or death from fire or explosion. Before starting the engine, operate the bilge blower or vent the engine compartment for at least five minutes.

NOTE: MerCruiser DTS models are equipped with SmartStart. The SmartStart feature incorporates push‑button starting. Rather than holding the start button or key switch to start the engine and then releasing it when the engine starts, SmartStart completely controls the starting process. When the start button is pushed, the DTS system signals the engine PCM to start the engine. If the engine does not start, the starting process times out after a few seconds or when the engine reaches 400 RPM. Attempting to start the engine with the engine already running will turn the engine off.

3. Turn the ignition key to the "RUN" position.

WARNING

4. Turn the ignition key switch to the "START" position then release, or depress the start/stop button and release. If the engine

is cold, allow the engine to operate at idle for 6–10 minutes or until the engine temperature reaches 60° C (140° F).

5. If the engine does not start after three attempts:

a. Push the throttle‑only button and position the remote control handle or throttle lever to the 1/4 throttle position. b. Turn the ignition key to "start." Release key when the engine starts and allow the switch to return to the "on" position.

6. If the engine does not start after step 5:

a. Move the remote control lever to the full throttle position, then return to 1/4 throttle. b. Turn the ignition key to "START." Release key when the engine starts and allow the switch to return to the "on" position.

7. Inspect the power package for fuel, oil, water, and exhaust leaks.

8. Move the control handle with a firm, quick motion forward to shift to forward gear, or backward to shift to reverse. After shifting,

advance throttle to desired setting.

NOTICE

Shifting into gear at engine speeds above idle will damage the drive system. Shift the drive into gear only when the engine is operating at idle.

Stopping the Engine

1. Move the remote control handle to neutral/idle and allow the engine to slow to idle speed. If the engine has been operated at

high speed for a long period of time, allow the engine to cool at idle speed for 3 to 5 minutes.

2. The engine can be stopped by any one of the following four methods:

a. Move the ignition key switch to the "ACCESSORY" or "OFF" position. The engine will stop and the control system will

be deactivated. b. Depress the start/stop button, if equipped. The engine will stop and the control system will remain active. c. Momentarily move the ignition key switch to the "START" position, then release immediately. The control system will

recognize that the engine is running and will stop the engine. The control system will remain active. Moving the ignition

key switch to the "START" position again will issue a start request to the control system and the control system will start

the engine, if appropriate. d. Activate the lanyard stop switch, if equipped. The engine will stop, but the control system will remain active. The control

system will not allow the engine to start if the lanyard stop switch is activated.

Throttle Only Operation

NOTE: When operating in throttle only (neutral) mode, the DTS Control System will not allow the engine speed to increase above 3500 RPM.

Console mount remote controls are equipped with a throttle‑only button. To activate throttle only mode:

1. Refer to the Remote Controls section for remote control features.

90-864197084 NOVEMBER 2008 Page 43

Page 52

Section 3 - On The Water

2. Move the control lever to the idle/neutral position.

3. Depress the throttle‑only button, and move the control lever to the idle/forward or idle/reverse position. The DTS control system will sound two beeps on the audio warning horn to indicate throttle only mode is active. On console mount remote controls, the neutral light will begin to blink.

4. Advancing the control lever beyond the idle/forward or idle/reverse position will cause engine speed to increase. IMPORTANT: Moving the control lever back to the idle/neutral position will not deactivate the throttle only mode or allow the

engine to shift into gear.

5. Throttle only mode is deactivated by moving the control lever to the idle/neutral position and pressing the throttle only button. Moving the control lever from the idle/neutral position to the idle/forward or idle/reverse position without pressing the throttle‑only button will just increase the engine speed. Be sure to take both engines out of throttle only before use.

Traditional Maneuvering with Steering and Thrust

You can maneuver your Axius‑equipped vessel much like a traditional sterndrive boat. However, the Axius drive system expands the maneuvering capability of your vessel at both slow and planing speeds. At slow speeds, the drive system is capable of directing the thrust to produce more responsive turning of the vessel. The Axius drive system features counter‑rotating propellers that do not produce any sideways motion when accelerating or slowing down.

NOTE: During slow‑speed turning with the wheel, the drive on the inside turns as much as 42° to create very tight turns. Unlike traditional boats, you can increase power to the inside drive to tighten the turn.

To Maneuver the Boat in Forward

Place one or both engines in forward gear and steer with the steering wheel as you would any comparable boat.

To Steer the Boat in Tight Turns at Low Speeds

• To turn the boat in tight turns at low speeds, turn the wheel in the direction of the turn.

• To increase the turn rate of the boat after the wheel is completely turned, you may increase the power to the inside drive.

To Spin the Boat at Low Speeds

• To spin to the right, place the starboard engine in reverse and the port engine in forward.

• To spin to the left, place the port engine in reverse and the starboard engine in forward.

• To increase the rate of turn, simultaneously adjust each ERC lever for more throttle.

Maneuvering with the Joystick

WARNING

The joystick provides an intuitive driver interface to maneuver the vessel. Operating the vessel with the joystick is well suited for close quarter operations and when docking. The computer control system automatically calculates the steering angle of each drive, the throttle level, and the proper gear to push or rotate the boat in a direction corresponding to a joystick movement or twist. For example, if you move the joystick sideways, the computer control system applies a thrust to the boat in the sideways direction. Rotating the joystick prompts the computer to create forces that rotate the boat around its center. You can move and rotate the joystick at the same time, allowing intricate movements in tight quarters.

The joystick is proportional, which means that the greater distance from the center that the joystick is moved, the more thrust that is applied to the boat in that direction, to move the boat.

The computer control system automatically attempts to dampen bow swinging during joystick operation. If the joystick is not twisted, the computer measures the yaw rate of the boat and actively counteracts the yaw motion of the boat.

For joystick movement of the boat:

1. Both engines must be running for the Joystick to operate.

2. For best control, trim both drives to the full down position.

3. Move both electronic remote control (ERC) levers to the neutral position.

4. Move the joystick in the direction that you want the boat to move, or twist the joystick in the direction that you want the boat to rotate. The joystick can be moved and rotated at the same time.

The following table gives some limited examples of the basic responses to inputs from the joystick.

Skyhook

WARNING

A rotating propeller, a moving boat, or a device attached to a moving boat can cause serious injury to people in the water. When Skyhook is engaged, the propellers rotate and the boat moves to maintain the position of the boat. Stop the engines immediately whenever anyone is in the water near the boat.

Skyhook uses GPS and the compass heading information to control the throttle, gear position and steering to maintain the boat's position within approximately 3 m (10 ft).

The Skyhook feature can hold your boat nearly stationary, for example, while you wait for a space at the fuel dock, or while waiting for a bridge to open. You can also use Skyhook to maintain your boat's position when the water is too deep for an anchor.

Skyhook should not be used when the boat is next to a dock, or any other object, including other anchored boats. Because Skyhook holds the boat in an approximate position, not a precise one, it can cause your boat to collide with objects close to the boat causing damage to the boat and the nearby objects. Occasionally the Skyhook system may apply a brief surge in power while holding a position. This may cause a person standing near the edge of the boat to lose their balance and fall.

To engage Skyhook the drives must be shifted into neutral. However, after engaging Skyhook the drive response is not the same as with drives normally shifted into neutral. The propellers will turn when Skyhook is activated, and propeller rotation may not be obvious. As in all boats when the engines are running, it is important to ensure that no one is in the water near the boat and to ensure that passengers are secure. Compliance with this practice is even more important when Skyhook is engaged.

Before engaging (activating) Skyhook the operator must:

• Inform passengers how Skyhook operates, to stay out of the water and off the swim platform, and to be alert for any sudden

shifts in the boats position.

• Check to see no one is on the swim platform, or in the water anywhere near the boat.

When Skyhook is engaged the operator must:

• Remain at the helm and maintain a vigilant watch.

• Disengage (deactivate) Skyhook if anyone enters the water or approaches the boat from the water.

The capability of most vessels limits the ability of Skyhook to counteract currents of up to 2 knots (2.3 MPH) when the boat is sideways to the current. If you notice your boat drifting sideways while Skyhook is engaged, move the bow or stern more directly into the current to help reduce the effects of the current.

WARNING

When the Skyhook is engaged, the boat stays in a preset position; however, Skyhook can disengage unexpectedly. When Skyhook disengages, the boat does not hold the preset position and may drift, causing the potential of damage or personal injury. The helm operator must be able to take control of the boat when using Skyhook.

Skyhook relies on an operational GPS receiver and operational heading sensor. Occasionally, due to imperfect satellite communications, the GPS signal may be temporarily unavailable. Skyhook will continue to operate through a GPS signal outage for up to 10 seconds, but disengages if the GPS signal outage persists. If Skyhook disengages, you are alerted by the sound of a horn and the indicator light on the Axius Premier Trackpad for the "SKYHOOK" button turns off. In such a circumstance, the boat will drift with the wind or current because the engines continue to run but the drive units are now in neutral.

Skyhook performance is largely dictated by the performance of the onboard Zeus GPS system. The Zeus GPS system is accurate within 3 meters (10 feet) when receiving a Wide Area Augmentation System (WAAS) correction. WAAS is a system of satellites and ground stations that provide GPS signal corrections. When WAAS is not available, the performance of the system maintains the boat within 20 meters (60 feet) of the desired position.

Label in the vicinity of the transom boarding area

IMPORTANT: If either of the labels cannot be located or are not legible, they must be replaced before engaging Skyhook. Contact the manufacturer of your boat, your Cummins distributor, or an Authorized Cummins MerCruiser Diesel Repair Facility and replace the labels.

NOTE: Skyhook will not engage while "DOCK" mode is engaged. Disengage "DOCK" mode prior to engaging "SKYHOOK."

1. Bring the boat to a stop and move the ERC levers to neutral. Skyhook will not engage until the boat is in neutral.

2. Inform passengers to stay out of the water and off the swim platform, and to be alert for any sudden shifts in the boats position when skyhook is engaged.

3. Ensure that no one is on the swim platform, or in the water anywhere near the boat.

Track Waypoint

WARNING

In some Precision Pilot modes—"Auto Heading," "Track Waypoint," and "Waypoint Sequence"—the boat navigates a preset course. The boat does not automatically respond to hazards such as other watercraft, obstacles, swimmers, or underwater terrain. Collision with these hazards could cause boat damage, serious injury, or death. The operator must stay at the helm, ready to evade hazards and warn others of course changes.

IMPORTANT: Track Waypoint can only be used with chart plotters approved by CMD. Track Waypoint allows the boat to automatically navigate to a specific waypoint or sequence of waypoints, called a waypoint route.

Waypoint data needs to be provided to VesselView by a third party chart plotter. Refer to your chart plotter's user manual for details.

Engaging Track Waypoint Mode

To engage the Track Waypoint mode of Axius Premier:

1. Turn on the chart plotter and select a single waypoint or waypoint route to be tracked.

2. Place at least one ERC handle in forward gear. Track Waypoint does not function if both handles are in neutral or reverse.

3. Manually steer the boat to the direction of the first waypoint and hold the boat steady at a safe operating speed.

4. Press the "TRACK WAYPOINT" button on the Axius Premier Trackpad. The "TRACK WAYPOINT" button light turns on and

a single horn beep sounds, indicating Track Waypoint engaged. Track Waypoint tracks to the first waypoint on the chart plotter course. Two horn beeps sound if Track Waypoint does not engage.

Cruise Control

These additional notes are exclusive to your package:

• You can change or disengage cruise through the screen at any time.

• Cruise resets when the key is turned off.

• If the cruise limit is changed while the levers are at WOT, cruise gradually changes to the new speed.

• Cruise does not disengage if the ERC levers are at a higher engine speed than the actual RPM. Bring the levers back to the forward detent to disengage.

Contingent Operations

Port Engine Only Operation

The force feedback feature of the steering wheel is only available when the starboard key switch is in the on position. If the starboard key switch is off or there has been damage to the starboard electrical system, the port control system monitors the steering wheel.

If only the port side is operational, or only the port key switch is in the on position, the force feedback system will not provide end stops for the steering wheel. In this case, the drive will turn in the direction of steering wheel rotation until the mechanical limits of the drive are reached.

NOTE: If the port electrical system is damaged, the steering wheel will operate normally with complete force feedback and end stops.

Note that joystick is not available in single‑engine operation. However, Axius features redundant track pad systems, so Auto Heading mode is still available during single‑engine operation.

Axius Shift Override—Emergency Procedure

If the VesselView display shows the error message "GEAR POS DIFF" and an engine will not start or will not shift into gear, there is a problem with the Electronic Shift Control (ESC) system. If one drive is working, you may operate on one engine and drive.

CAUTION

Using the emergency procedure to manually shift the drive disengages shift control at the helm. To avoid damage or injury, drive cautiously when a gear is engaged manually. To stop the drive and its propeller, you must turn the key switch to the off position.

You can disengage the shift actuator to manually shift the drive into neutral for starting and into forward gear position for operation. Engine speed will be limited to 1000–1200 RPM while operating in emergency shift override.

To disengage the shift actuator:

1. Turn the ignition switch to the off position and engage the emergency lanyard, if equipped.

WARNING

Engine components and fluids are hot and can cause serious injury or death. Allow the engine to cool before removing any components or opening any fluid hoses.

2. Unplug the shift actuator wiring harness connector.

3. Move the shift lever into the neutral position. The shift actuator is in the neutral position when the shift lever is straight up and

the shift interrupt switch is fully engaged.

4. With the drive in neutral, place the ERC into the neutral (idle) position.

5. Reset the lanyard.

WARNING

6. Ensure that no one is in the water near the boat, then start the engine.

7. With the engine running at idle speed, the drive can be shifted into gear and out of gear by manually moving the shift lever.

NOTE: Engine speed will be limited to 1000–1200 RPM while operating in emergency shift override. The Auto Heading feature using the Axius track pad will still function but is limited to this reduced RPM setting.

IMPORTANT: The boat's stopping distance increases during manual gear engagement operation.

Section 4 - Specifications

Fuel Requirements

IMPORTANT: Use of improper gasoline can damage your engine. Engine damage resulting from the use of improper gasoline is considered misuse of the engine, and damage caused thereby will not be covered under the limited warranty.

Fuel Ratings

Mercury MerCruiser engines will operate satisfactorily when using a major brand of unleaded gasoline meeting the following specifications:

USA and Canada—having a posted pump Octane Rating of 87 (R+M)/2 minimum. Premium gasoline [92 (R+M)/2 Octane] is also acceptable. Do not use leaded gasoline.

Outside USA and Canada—having a posted pump Octane Rating of 90 RON minimum. Premium gasoline (98 RON) is also acceptable. If unleaded gasoline is not available, use a major brand of leaded gasoline.

Using Reformulated (Oxygenated) Gasolines (USA Only)

This type of gasoline is required in certain areas of the USA. The 2 types of oxygenates used in these fuels is Alcohol (Ethanol) or Ether (MTBE or ETBE). If Ethanol is the oxygenate that is used in the gasoline in your area, refer to Gasolines Containing Alcohol.

These Reformulated Gasolines are acceptable for use in your Mercury MerCruiser engine.

Gasolines Containing Alcohol

If the gasoline in your area contains either methanol (methyl alcohol) or ethanol (ethyl alcohol), you should be aware of certain adverse effects that can occur. These adverse effects are more severe with methanol. Increasing the percentage of alcohol in the fuel can also worsen these adverse effects.

Some of these adverse effects are caused because the alcohol in the gasoline can absorb moisture from the air, resulting in a separation of the water/alcohol from the gasoline in the fuel tank.

The fuel system components on your Mercury MerCruiser engine will withstand up to 10% alcohol content in the gasoline. We do not know what percentage your boat's fuel system will withstand. Contact your boat manufacturer for specific recommendations on the boat's fuel system components (fuel tanks, fuel lines, and fittings). Be aware that gasolines containing alcohol may increase:

• Corrosion of metal parts

• Deterioration of rubber or plastic parts

• Fuel permeation through rubber fuel lines

• Difficulty starting and operating the engine

WARNING

Fuel leakage is a fire or explosion hazard, which can cause serious injury or death. Periodically inspect all fuel system components for leaks, softening, hardening, swelling, or corrosion, particularly after storage. Any sign of leakage or deterioration requires replacement before further engine operation.

Because of possible adverse effects of alcohol in gasoline, we recommend only alcohol‑free gasoline when possible. If the only fuel available contains alcohol or if you do not know whether the fuel contains alcohol, inspect for leaks and abnormalities more frequently.

IMPORTANT: When operating a Mercury MerCruiser engine on gasoline containing alcohol, do not store the gasoline in the fuel tank for long periods. Whereas cars normally consume alcohol‑blend fuels before they can absorb enough moisture to cause trouble, boats often sit idle long enough for phase separation to take place. In addition, internal corrosion may take place during storage if alcohol has washed protective oil films from internal components.

Engine Oil

To help obtain optimum engine performance and to provide maximum protection, we strongly recommend the use of the following oils listed in the order of recommendation:

1. MerCruiser / Quicksilver Synthetic Blend, NMMA FC‑W rated, 4 cycle oil.

2. MerCruiser / Quicksilver 25W40 NMMA FC‑W rated oil.

3. A NMMA FC‑W rated oil.

4. MerCruiser / Quicksilver 4‑cycle 25W40, non FC‑W rated oil.

5. A good grade straight weight detergent automotive oil per the operating chart below.

Section 4 - Specifications

NOTE: The use of non‑detergent oils, multi‑viscosity oils (other than as specified), non FC‑W rated synthetic oils, low quality oils or oils that contain solid additives are specifically not recommended.

Section 5 - Maintenance

Owner/Operator Responsibilities

It is the operator's responsibility to perform all safety checks, to ensure that all lubrication and maintenance instructions are complied with for safe operation and to return the unit to an authorized Mercury MerCruiser dealer for a periodic checkup.

Normal maintenance service and replacement parts are the responsibility of the owner/operator and as such, are not considered defects in workmanship or material within the terms of the warranty. Individual operating habits and usage contribute to the need for maintenance service.

Proper maintenance and care of your power package will ensure optimum performance and dependability and will keep your overall operating expenses at a minimum. See your authorized Mercury MerCruiser dealer for service aids.

Dealer Responsibilities

In general, a dealer's responsibilities to the customer include predelivery inspection and preparation such as:

• Ensure that the boat is properly equipped.

• Prior to delivery, make certain that the Mercury MerCruiser power package and other equipment are in proper operating condition.

• Make all necessary adjustments for maximum efficiency.

• Familiarize the customer with the on‑board equipment.

• Explain and demonstrate the operation of the power package and boat.

• Provide you with a copy of a Predelivery Inspection Checklist.

• Your selling dealer should fill out the Warranty Registration Card completely and mail it to the factory immediately upon sale of the new product.

Maintenance

WARNING

Performing service or maintenance without first disconnecting the battery can cause product damage, personal injury, or death due to fire, explosion, electrical shock, or unexpected engine starting. Always disconnect the battery cables from the battery before maintaining, servicing, installing, or removing engine or drive components.

WARNING

Fuel vapors trapped in the engine compartment may be an irritant, cause difficulty breathing, or may ignite resulting in a fire or explosion. Always ventilate the engine compartment before servicing the power package.

IMPORTANT: Refer to the maintenance schedule for the complete listing of all scheduled maintenance to be performed. Some items should be performed only by an authorized Mercury MerCruiser dealer only. Before attempting maintenance or repair procedures not covered in this manual, we recommend that you purchase a Mercury MerCruiser service manual and read it thoroughly.

NOTE: Maintenance points are color‑coded for ease of identification.

Do‑It‑Yourself Maintenance Suggestions

Present day marine equipment, such as your Mercury MerCruiser power package, are highly technical pieces of machinery. Electronic ignition and special fuel delivery systems provide greater fuel economies, but also are more complex for the untrained mechanic.

If you are one of those persons who likes to do it yourself, here are some suggestions for you.

• Do not attempt any repairs unless you are aware of the Cautions, Warnings and procedures required. Your safety is our concern.

• If you attempt to service the product yourself, we suggest you order the service manual for that model. The service manual outlines the correct procedures to follow. It is written for the trained mechanic, so there may be procedures you don't understand. Do not attempt repairs if you do not understand the procedures.

Page 84 90-864197084 NOVEMBER 2008

Page 93

Section 5 - Maintenance

• There are special tools and equipment that are required to perform some repairs. Do not attempt these repairs unless you

have these special tools and/or equipment. You can cause damage to the product in excess of the cost a dealer would charge you.

• Also, if you partially disassemble an engine or drive assembly and are unable to repair it, the dealer's mechanic must

reassemble the components and test to determine the problem. This will cost you more than taking it to the dealer immediately upon having a problem. It may be a very simple adjustment to correct the problem.

• Do not telephone the dealer, service office or the factory to attempt for them to diagnose a problem or to request the repair

procedure. It is difficult for them to diagnose a problem over the telephone.

Your authorized dealer is there to service your power package. They have qualified factory trained mechanics. It is recommended you have the dealer do periodic maintenance checks on your power package. Have them winterize it in the

fall and service it before the boating season. This will reduce the possibility of any problems occurring during your boating season when you want trouble free boating pleasure.

Inspection

Inspect your power package often, and at regular intervals, to help maintain its top operating performance and correct potential problems before they occur. The entire power package should be checked carefully, including all accessible engine parts.

• Check for loose, damaged or missing parts, hoses and clamps; tighten or replace as necessary.

• Check plug leads and electrical leads for damage.

• Remove and inspect the propeller. If badly nicked, bent or cracked, contact your authorized Mercury MerCruiser dealer.

• Repair nicks and corrosion damage on power package exterior finish. Contact your authorized Mercury MerCruiser dealer.
