Recreational Use Diesel Sterndrive Limited Warranty

I. WHAT IS COVERED

Mercury Marine warrants its new products to be free of defects in material and workmanship during the period described below.

II. DURATION OF COVERAGE

This Limited Warranty provides coverage for one (1) year from the date the product is first sold to a recreational use retail purchaser, or the date on which the product is first put into service, whichever occurs first. Commercial use of the product voids the warranty. Commercial use is defined as any work or employment related use of the product, or any use of the product which 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. Unexpired warranty coverage can be transferred to a subsequent purchaser upon proper re-registration of the product.

III. 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 Mercury Marine specified pre-delivery inspection process 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 may void the warranty at the sole discretion of Mercury Marine. Routine maintenance outlined in the Operation, Maintenance and Warranty Manual must be timely performed in order to obtain warranty coverage. If this maintenance is performed by the retail customer Mercury Marine reserves the right to make future warranty coverage contingent on proof of proper maintenance.

IV. WHAT MERCURY WILL DO

Mercury’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 re-manufactured parts, or refunding the purchase price of the Mercury product. Mercury reserves the right to improve or modify products from time to time without assuming an obligation to modify products previously manufactured.

V. 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, written notice must be given to Mercury . We 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. The warranty registration card is the only valid registration identification and must be presented to the dealer at the time warranty service is requested in order to obtain coverage.

VI. WHAT IS NOT COVERED

This limited warranty does not cover routine maintenance items, tune ups, adjustments, normal wear and tear, damage caused by abuse, abnormal use, use of a propeller or gear ratio that does not allow the engine to run in its recommended rpm range (see the Operation, Maintenance and Warranty Manual), operation of the product in a manner inconsistent with the recommended operation/duty cycle section of the Operation, Maintenance and Warranty Manual, neglect, accident, submersion, improper installation (proper installation specifications and techniques are set forth in the installation instructions for t h e product), improper service, use of an accessory or part which damages the Mercury product and was not manufactured or sold by us, jet pump impellers and liners, operation with fuels, oils or lubricants which are not suitable for use with the product (see the Operation, Maintenance and Warranty Manual), alteration or removal of parts, or water entering the engine through the fuel intake, air intake or exhaust system. Use of the product for racing or other competitive activity, or operating with a racing type lower unit, at any point, even by a prior owner of the product, voids the warranty.

VII. Expenses related to haul-out, launch, towing, storage, telephone, rental, inconvenience, slip fees, in-

surance cov e r age, loan payments, loss of time, loss of income, or any other type of incidental or consequential damages are not covered by this warranty . Also, expenses associated with the removal and/ or replacement of boat partitions or material caused by boat design for access to the product are not covered by this warranty.

VIII. No individual or entity, including Mercury Marine authorized dealers, has been given authority by Mer-

cury Marine to make any affirmation, representation or warranty regarding the product, other than those contained in this limited warranty , and if made, shall not be enforceable against Mercury Marine.

IX. For additional information regarding events and circumstances covered by this warranty, and those

that are not, see the W arranty Coverage section of the Operation, Maintenance and Warranty Manual, incorporated by reference into this warranty.

X. DISCLAIMERS AND LIMITATIONS

THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE EXPRESSLY DISCLAIMED. TO THE EXTENT THAT THEY CANNOT BE DISCLAIMED, THE IMPLIED WARRANTIES ARE LIMITED IN DURATION TO THE LIFE OF THE EXPRESS WARRANTY. INCIDENTAL AND CONSEQUENTIAL DAMAGES ARE EXCLUDED FROM COVERAGE UNDER THIS WARRANTY. SOME ST ATES/COUNTRIES DO NOT ALLOW FOR THE DISCLAIMERS, LIMITATIONS AND EXCLUSIONS IDENTIFIED ABOVE, AS A RESULT, THEY MA Y NOT APPLY TO YOU. THIS WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS, AND YOU MAY ALSO HAVE OTHER LEGAL RIGHTS WHICH VARY FROM STATE TO STATE AND COUNTRY TO COUNTRY.

Warranty Coverage and Exclusions

The purpose of this section is to help eliminate some of the more common misunderstandings regarding warranty coverage. The following list explains some of the types of services that are not covered by warranty.

Keep in mind that warranty covers repairs that are needed within the warranty period because of defects in material and workmanship. Installation errors, accidents, normal wear and a variety of other causes that affect the product are not covered.

Lanyard Stop Switch

General Information

The purpose of a lanyard stop switch (1) is to turn off the engine when the operator moves far enough away from the operator’s position (as in accidental ejection from the operator’s position) to activate the switch. Some remote control units are equipped with a lanyard stop switch. A lanyard stop switch can be installed on the dashboard or side adjacent to the operator’s position.

The lanyard is a cord usually between 4 and 5 feet (1220 and 1524 mm) in length when stretched out with an element on one end made to be inserted into the switch and a snap (2) on the other end for attaching to the operator. The lanyard is coiled to make its at-rest condition as short as possible so as to minimize the likelihood of lanyard entanglement with nearby objects. It is made as long as it is in its stretched condition 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.

IMPORTANT: The purpose of a lanyard stop switch is to stop the engine when the operator moves far enough away from the operator’s position to activate the switch. This would occur if the operator accidentally falls overboard or moves within the boat a sufficient distance from the operator’s position. Accidental ejections and falls overboard are more likely to occur in certain types of boats such as low sided sport boats or bass boats, and high-performance boats. Accidental ejections and falls overboard are also likely to occur as a result of poor operating practices such as sitting on the back of the seat or gunwale at planing speeds, standing at planing speeds, sitting on elevated fishing boat decks, operating at planing speeds in shallow or obstacle-infested waters, releasing your grip on a steering wheel that is pulling in one direction, drinking alcohol or consuming drugs, or daring, high-speed boat maneuvers.

74608

While activation of the lanyard stop switch will stop the engine immediately , a 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

Should the operator fall out of the boat, the possibility of serious injury or death from being run over by the boat can be greatly reduced by stopping the engine immediately. Always properly connect both ends of the stop switch lanyard to the stop switch and the operator.

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:

1 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 gear case or propeller.

2 Loss of power and directional control in heavy seas, strong current or high winds. 3 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.

CD543

Wave And Wake Jumping

Operating recreational boats over waves and wakes is a natural part of boating. However, when this activity is done with 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 case 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 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 steer sharply to one side.

WARNING

Avoid serious injury or death from being thrown within or out of a boat when it lands after jumping a wave or wake. Avoid wave or wake jumping whenever possible. Instruct all occupants that if a wake or wave jump occurs, get low and hang on to any boat hand hold.

CD544

Impact With Underwater Hazards

Reduce speed and proceed with caution whenever you’re driving a boat in shallow water areas or in areas where the waters are suspected of having underwater obstacles that could be struck by the sterndrive or the boat bottom. 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 minimum planing speed of (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 occu-

pants 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 sterndrive 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 engine as soon as possible and inspect the sterndrive unit for any broken or loose parts. If damage is present or suspected, the power package should be taken to an authorized dealer for a thorough inspection and necessary repair.

The boat should also be checked for any hull fractures, transom fractures, water leaks. Operating a damaged sterndrive could cause additional damage to other parts of the power package, or could

affect control of the boat. If continued running is necessary, do so at greatly reduced speeds.

WARNING

Avoid serious injury or death from loss of boat control. Continued boating with major impact damage can result in sudden component failure with or without subsequent impacts. Have the power package thoroughly inspected and any necessary repairs made.

CA802

Operating With Low Water Inlets In Shallow Water

76363

75827

CAUTION

Serious engine damage could occur by failing to follow these instructions. Sand, silt or mud could be sucked into the water inlets restricting or shutting off the water supply to the engine.

Extreme care should be exercised when operating a boat equipped with low water inlets (A) while maneuvering in shallow water. Also, avoid beaching the boat with the engine(s) running.

CA281

Safe Boating Suggestions

In order to safely enjoy the waterways, familiarize yourself with local and other governmental boating regulations and restrictions, and consider the following suggestions.

• Know and obey all nautical rules and laws of the waterways. Boat operators should complete a boating

safety course. Courses are offered in the U.S.A. by (1) The U.S. Coast Guard Auxiliary, (2) The Power Squadron, (3) The Red Cross and (4) your state or provincial boating law enforcement agency. Inquiries may be made to the Boating Hotline, 1-800-368-5647 or the Boat U.S. Foundation information number

1-800-336-BOAT. We strongly recommend that all powerboat operators attend one of these courses. You should also review the NMMA Sources of Waterway Information booklet. It lists regional sources of safety,

cruising and local navigation and is available at no charge by writing to: Sources of Waterway Information

National Marine Manufacturers Association 410 N. Michigan Avenue Chicago, IL 60611 U.S.A.

• Perform safety checks and required maintenance. Follow a regular schedule and ensure that all repairs

are properly made.

• Check safety equipment on board. Here are suggestions of the types of safety equipment to carry when

boating: (1) Approved fire extinguisher(s); paddle or oar. (2) Signal devices: flashlight, rockets or flares, flag and whistle or horn.

(3) Spare propeller, thrust hubs and an appropriate wrench. (4) Tools for necessary minor repairs; first aid kit and book.

(5) Anchor and extra anchor line; water-proof storage containers. (6) Manual bilge pump and extra drain plugs; compass and map or chart of area. (7) Spare operating equipment; batteries, bulbs, fuses, etc. (8) Transistor radio (9) Drinking water

• Know signs of weather change and avoid foul weather and rough-sea boating.

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

• Passenger boarding. Stop the engine whenever passengers are boarding, unloading or are near the back

(stern) of the boat. Just shifting the drive unit into neutral is not sufficient.

• Use personal flotation devices. Federal Law requires that there be a U. S. Coast Guard approved, wear-

able-type life jacket (personal flotation device), correctly sized and readily accessible for every person on

board, plus a throwable cushion or ring. W e strongly advise that everyone wear a life jacket at all times while

in the boat.

• Prepare other boat operators. Instruct at least one person on board in the basics of starting and operating

the engine and boat handling in case the driver becomes disabled or falls overboard.

• Do not overload your boat. Most boats are rated and certified for maximum load (weight) capacities (refer

to your boat capacity plate). When in doubt, contact your dealer or the boats manufacturer. Know your boat’s

operating and loading limitations.

• Make sure everyone in the boat is properly seated. Don’t allow anyone to sit or ride on any part of the boat

that was not intended for such use. This includes backs of seats, gunwales, transom, bow, decks, raised fish-

ing seats, any rotating fishing seat; anywhere that sudden unexpected acceleration, sudden stopping, unex-

pected loss of boat control or sudden boat movement could cause a person to be thrown overboard or into

the boat.

• Never be under the influence of alcohol or drugs while boating (it is the law). They impair your judgment

and greatly reduce your ability to react quickly.

• Know your boating area and avoid hazardous locations.

• Be alert. The operator of the boat is responsible by law to “maintain a proper lookout by sight (and hearing).”

The operator must have an unobstructed view particularly to the front. No passengers, load, or fishing seats should block the operators view when operating the boat above idle or planing transition speed. Watch “the other guy,” the water and your wake.

• Never drive your boat directly behind a water skier in case the skier falls. As an example, your boat trav-

eling at 25 miles per hour (40 km/hr) in 5 seconds will overtake a fallen skier who was 200 feet in front of you.

• Watch fallen skiers. When using your boat for water skiing or similar activities, always keep a fallen or down

skier on the operator’s side of the boat while returning to attend the skier. The operator should always have the down skier in sight and never back up to the skier or anyone in the water.

• Report accidents. Boat operators are required by law to file a Boating Accident Report with their state boat-

ing law enforcement agency when their boat is involved in certain boating accidents. A boating accident must be reported if (1) there is loss of life or probable loss of life, (2) there is personal injury requiring medical treatment beyond first aid, (3) there is damage to boats or other property where the damage value exceeds $500.00 or (4) there is complete loss of the boat. Seek further assistance from local law enforcement.

CA282

Protecting People In The Water

While You Are Cruising

It is very difficult for a person standing or floating in the water to take quick action to avoid a boat heading in his/her direction even at slow speed.

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 (coasting) and the drive unit is in neutral position, 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

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

WARNING

Stop your engine immediately whenever anyone in the water is near your boat. Serious injury to the person in the water is likely if contacted by a rotating propeller, a moving boat, a moving gear case, or any solid device rigidly attached to a moving boat or gear case.

CC828

High-Speed And High-Performance Boat 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 familiarization demonstration ride with your dealer or an operator experienced with your boat. For additional information, obtain a copy of our “Hi-Performance Boat Operation” booklet (Part Number 90-849250--1) from your dealer, distributor, or Mercury Marine.

Conditions Affecting Operation

CD4

Weight Distribution

Positioning of weight (passengers and gear) inside the boat has the following effects: A. Shifting weight to rear (stern) will:

• Generally increases speed and engine rpm.

• At extremes, can cause boat to porpoise.

• Causes bow to bounce in choppy water.

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

B. Shifting weight to front (bow) will:

• Improves ease of planing on some boats.

• Improves rough water ride.

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

CA8

Bottom Of Boat

To maintain maximum speed, the following conditions of the boat bottom should be observed. A. Clean, free of barnacles and marine growth. B. Free of distortion; nearly flat where it contacts the water. C. Straight and smooth, fore and aft. Marine vegetation may accumulate when boat is docked. This growth must be removed before operation; it may

clog water inlets and cause engine to over heat.

CA9

Cavitation

Cavitation occurs when water flow cannot follow the contour of a fast-moving underwater object, such as a gear housing or propeller. Cavitation permits the propeller to speed up, but the boat speed to reduce. Cavitation can seriously erode the surface of the gear housing or propeller. Common causes of cavitation are:

A. Weeds or other debris snagged on propeller or gear housing. B. Bent propeller blade or damaged gear housing skew . C. Raised burrs or sharp edges on propeller or gear housing.

CA10

Ventilation

Ventilation is caused by surface air or exhaust gases which are introduced around the propeller resulting in propeller speedup and a reduction in boat speed. Excessive ventilation is annoying and usually caused by:

A. Drive unit trimmed out too far. B. A missing propeller diffuser ring. C. A damaged propeller or gear housing, which allows exhaust gases to escape between propeller and gear

housing. D. Drive unit installed too high on transom.

CD449

Propeller Selection

It is the responsibility of the boat manufacturer and/or the selling dealer to equip the power package with the correct propeller(s).

Select a propeller that will allow the engine power package to operate at or near the top end of the recommended wide-open-throttle operating rpm range with a normal load. High rpm, caused by an excessive trim angle, should not be used in determining correct propeller selection.

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/or damage. Generally, there is a 200 rpm change between propeller pitches.

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

• Warmer weather and greater humidity cause an rpm loss.

• Operating in a higher elevation causes an rpm loss.

• Operating with a damaged propeller or dirty boat bottom causes an rpm loss.

• Operating with increased load (additional passengers, pulling skiers, etc.).

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

CA12

How Elevation And Climate Affect Performance

Elevation has a very noticeable effect on the wide-open-throttle power of an engine. Since air (containing oxygen) gets thinner as elevation increases, the engine begins to starve for air. Humidity, barometric pressure and temperature do have a noticeable effect on the density of air. Heat and humidity thin the air. This condition can become particularly annoying when an engine is propped out on a cool, dry day in spring and later , on a hot, sultry day in August, doesn’t have its old zip.

Although some performance can be regained by dropping to a lower-pitch propeller , the basic problem still exists. In some cases, a gear-ratio change to more reduction is possible and very beneficial.

Summer conditions of high temperature, low barometric pressure and high humidity all combine to reduce the engine power. This, in turn, is reflected in decreased boat speeds, as much as 2 or 3 miles per hour in some cases. Nothing will regain this speed for the boater, but the coming of cool, dry weather.

In pointing out the practical consequences of weather effects, an engine -- running on a hot, humid summer day

-- may encounter a loss of as much as 14% of the horsepower it would produce on a dry brisk spring or fall day. With the drop in available horsepower, this propeller will, in effect, become too large. Consequently, the engine operates at less than its recommended rpm. This will result in further loss of horsepower at the propeller with another decrease in boat speed. This secondary loss, however, can be somewhat regained by switching to a lower-pitch propeller that allows the engine to again run at recommended rpm.

For boaters to realize optimum engine performance under changing weather conditions, it is essential that the engine be propped to allow it to operate at or near the top end of the recommended maximum rpm range at wideopen-throttle with a normal boat load.

Not only does this allow the engine to develop full power, but equally important is the fact that the engine also will be operating in an rpm range that discourages damaging detonation. This, of course, enhances overall reliability and durability of the engine.

Important Information

Operation and Maintenance

OWNER/OPERATOR RESPONSIBILITIES

It is the operator’s responsibility to perform all safety checks, ensure that all lubrication and maintenance instructions are complied with for safe operation, and return the unit to an Authorized 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 sterndrive package will assure optimum performance and dependability , and will keep your overall operating expenses at a minimum. See your Authorized MerCruiser Dealer for service aids.

CD451

DEALER RESPONSIBILITIES

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

• Make sure that the boat is properly equipped.

• Prior to delivery, make certain that the MerCruiser sterndrive 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 complete power package and boat.

• At the time of delivery, the dealer should 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 (branch

or distributor) immediately upon sale of the new product.

CD608

Sterndrive Unit 10-Hour Break-In Period

It is especially important that the following procedure be used on new sterndrive units. This break-in procedure allows the proper seating of drive unit gears and related components, which greatly reduces the likelihood of problems.

1. Avoid full throttle starts.

2. DO NOT operate at any one constant speed for extended periods of time.

3. DO NOT exceed 75% of full throttle during the first 5 hours. During the next 5 hours, operate at intermittent

full throttle.

4. Drive unit should be shifted into forward gear a minimum of 10 times during break-in, with run-in time at

moderate rpm after each shift.

CA414

End of First Season Checkup

At the end of the first season of operation, an Authorized MerCruiser Dealer should be contacted to discuss and/or perform various scheduled maintenance items. If you are in an area where the product is operated continuously (year-round operation), you should contact your dealer at the end of the first 100 hours of operation, or once yearly, whichever occurs first.

CD452

Freezing Temperature And Cold Weather Operation

IMPORTANT: If boat is operated during periods of freezing temperature, precautions must be taken to prevent freezing damage to the sterndrive. Refer to “Cold Weather or Extended Storage” for related information and draining instructions.

CA17

Drive Unit Impact Protection

The Power Trim hydraulic system is designed to provide impact protection for drive unit. If a submerged object is struck while boat is moving forward, the hydraulic system will cushion kick-up of drive unit as it clears the object, reducing damage to unit. After drive unit has cleared object, the hydraulic system allows drive unit to return to original operating position, preventing loss of steering control and engine over speed.

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

If drive unit should strike a submerged object, stop engine as soon as possible and inspect drive unit for damage. If damage is present or suspected, boat should be taken to an Authorized MerCruiser Dealer for thorough inspection and necessary repair . Operating a damaged drive unit could cause additional damage to other parts of drive unit, or could affect control of boat. If continued running is necessary, do so at greatly reduced speeds.

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

CA408

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 rise to come in contact with your power package. Components on your engine will be damaged if submerged. Damage caused by submersion is not covered by the MerCruiser Limited Warranty.

CA19

Trailering Boat

Boat can be trailered with drive unit in up or down position. Adequate road clearance is required between road and gear housing skeg when trailering with drive unit in down position.

If adequate road clearance is a problem, place drive unit in full trailer position and support with an optional trailer kit which is available from your Authorized MerCruiser Dealer.

CA20

Launching And Boat Operation Care

CAUTION

During launching from a trailer , if the unloading ramp is steep or the trailer bed must be tilted, the boat may enter the water rapidly and at a steep angle. This may force water through the exhaust system into the cylinders. The more weight on the transom, the more likely this is to occur.

Slowing down rapidly or stopping suddenly may cause a following wave to “swamp” the transom. In this instance, water may enter the cylinders through the exhaust system.

When backing up rapidly, the same situation may occur as stated in the preceding paragraph.

In any of these situations, water entering the engine could cause severe damage to internal parts. Refer to “Attention Required After Submersion.”

CD453

Stolen Sterndrive Unit

If your sterndrive is stolen, immediately advise the local authorities and Mercury Marine of the model and serial number(s) and to whom the recovery is to be reported. This “Stolen Sterndrive” information is placed into a file at Mercury Marine to aid authorities and dealers in recovery of stolen motors.

CD615

Do-It-Yourself Maintenance Suggestions

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

• Present-day marine equipment, such as your Mercury MerCruiser sterndrive unit, are highly technical pieces

of machinery. They are more complex for the untrained mechanic.

• Do not attempt any repairs which are not covered in this manual unless you are aware of the precautions

(“Cautions” and “Warnings”) and procedures required. Your safety is of 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.

• 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 request

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

• Your Authorized Dealer is there to service your sterndrive. 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.

CA284

Power Trim

Power T rim allows the operator to adjust the drive angle, while underway, to provide the ideal boat angle for varying load and water conditions. Also, the Power Trim system “Trailering” feature allows the operator to raise and lower the drive unit for trailering, beaching, launching and low speed (below 1200 rpm engine speed), shallow water operation.

CAUTION

Never trim the drive unit UP/OUT using TRAILER switch while boat is underway at engine speeds above 1200 rpm. Use extreme caution when operating with drive unit raised. Severe damage to the drive unit may result if unit is raised beyond the gimbal ring support flanges at engine speeds above 1200 rpm.

1 In most cases, best overall performance is obtained with the drive unit adjusted so the boat bottom will run

at a 3° to 5° angle to the water.

Trimming Drive Unit UP/OUT Can:

• Generally increase top speed.

• Increase clearance over submerged objects or a shallow bottom.

• Cause 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.

Trimming Drive Unit DOWN/IN Can:

• Lower the bow.

• Help the boat accelerate and plane off quicker.

• Generally improve the ride in choppy water.

• In most cases, reduce boat speed.

• If in excess, lower the bow of some boats to a point at which they begin to plow with their bow in the water

while on plane. This can result in an unexpected turn in either direction called “bow steering” or “over steering”

if any turn is attempted, or if a significant wave is encountered.

Corrosion And Corrosion Protection

Whenever two or more dissimilar metals (like those found on the stern drive) are submerged in a conductive solution, such as saltwater, polluted water , or water with a high mineral content, a chemical reaction takes place causing electrical current to flow between metals. The electrical current flow causes the metal that is most chemically active, or anodic, to erode. This is known as galvanic corrosion and, if not controlled, it will in time cause the need for replacement of power package components exposed to water.

IMPORTANT: Replace sacrificial anodes if eroded 50% or more.

1 Universal Anodic Plate - serves as a sacrificial anode.

Remove plug from drive shaft housing to access attaching screw and insert 1/2 inch socket. Unthread attaching screw and remove universal anodic plate. Do not remove screw. Clean or scrape mounting surfaces to bare metal for proper contact. Install new anodic plate and tighten screw securely. Install plug.

2 Anodic Plate - serves as a sacrificial anode. Unscrew both attaching screws and remove. Clean or scrape

mounting surfaces to bare metal for proper contact. Install a new anodic plate and tighten securely.

3 MerCathode System - should be tested to ensure adequate output..

Test should be made where boat is moored, using Quicksilver Reference Electrode and Test Meter . Contact your Authorized MerCruiser Dealer to arrange for this test.

CB621

71966

CA535

72032

1 Trim Cylinder Anodes - are mounted on each trim cylinder. To replace the trim cylinder anodes:

A Remove two screws from each anode. B Clean mounting surfaces down to bare metal for proper contact.

CB702

2 Bearing Carrier Anode (Bravo One Models) - is located in front of the propeller, between the front side of

the propeller and the gear housing. Refer to “Propeller” section in this manual for propeller removal and installation. To replace the propeller anode:

A Remove propeller. B Remove two screws from anode. C Install new anode and tighten securely. D Reinstall propeller. See “Propeller Installation” for proper tightening.

CA537

In addition to the corrosion protection devices, the following steps should be taken to inhibit corrosion:

IMPORT ANT: Corrosion damage that results from the improper application of anti-fouling paint will not be covered by the limited warranty.

1 Painting Boat Hull or Boat Transom: Anti-fouling paint may be applied to boat hull and boat transom, but

you must observe the following precautions:

IMPORTANT: DO NOT paint anodes or MerCathode System reference electrode and anode, as this will render them ineffective as galvanic corrosion inhibitors.

IMPORTANT: If anti-fouling protection is required for boat hull or boat transom

, copper or tin base paints, if not prohibited by law, can be used. If using copper or tin based anti-fouling paints, observe the following:

2 Avoid any electrical interconnection between the MerCruiser Product, Anodic Blocks, or MerCathode

System and the paint by allowing a minimum of 1-1/2 in. (40mm) UNPAINTED area on transom of the boat around these items.

3 Painting Drive Unit or Transom Assembly: Drive unit and transom assembly should be painted with a good

quality marine paint or an anti-fouling paint that DOES NOT conduct electrical current. DO NOT paint drain holes, anodes, MerCathode system, and items specified by boat manufacturer.

4 On the boat exterior surfaces, the use of certain mild household cleaners, used for the removal of mineral

and lime deposits, can be helpful if the finish is dull or discolored. Such cleaners are particularly useful in the removal of the unsightly, white deposits on the driveshaft housing or transom.

5 Spray power package components on inside of boat every 2-3 weeks with Quicksilver Corrosion Guard to

protect finish from dulling and corrosion. External power package components may also be sprayed.

6 All lubrication points, especially steering system, shift and throttle linkages, should be kept well lubricated. 7 Flush raw water cooling system periodically, preferably after each use.
