Features and Controls

E‑Stop (Emergency Stop) Switch, If Equipped
An E‑stop (emergency stop) switch turns off the engines in an emergency situation, such as a person overboard or a tangled propeller. When activated, an E‑stop switch interrupts the power supply to the engine and transmission. If the boat is equipped with an E‑stop switch at the helm, the E‑stop switch turns off all of the engines. The E‑stop switch on a Vessel Interface Panel (VIP) turns off only the engine connected to VIP.

Section 2 - Getting to Know Your Power Package
27198
Activation of an E‑stop switch stops the engine, or engines, immediately, but the boat can continue to coast for some distance depending upon the velocity and degree of any turn at shutdown. 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, and passengers in the front of the boat could be ejected over the bow and possibly struck by the propulsion or steering components.
The operator can lose power and directional control in heavy seas, strong current, or high winds.
The operator can lose control when docking.
Restarting an engine using the key switch or start button after an E‑stop shutdown without first turning the key switch to the off position for at least 30 seconds will restart the engine but cause fault codes to be set. Unless you are in a potentially hazardous situation, turn the key switch off and wait at least 30 seconds before restarting the engine or engines. If after restarting some fault codes are still being displayed, contact your Authorized Cummins MerCruiser Diesel Repair Facility.

Electronic Helm Steering

The Electronic Helm Steering is a true drive‑by‑wire system that controls the steering through electronic signals. The feel of the steering is created by computer‑designated resistance.
We recommend that you drive carefully until you have a chance to explore the Zeus system's handling characteristics in an open area without obstructions or other boat traffic, and you are familiar with the boat's responses. The first few maneuvers at speed can be more abrupt than expected.
Dual‑Handle Electronic Remote Control (ERC)—Features and Operation
OPERATION
The electronic remote control (ERC) handle controls the operation of shift and throttle. Push the control handle forward from neutral to the first detent for forward gear. Continue pushing the handle forward to increase speed. Pull the control handle from the forward position to the neutral position to decrease speed and eventually stop. Pull the control handle back from neutral to the first detent for reverse gear. Continue pulling the handle back to increase speed in reverse.
NOTE: In certain modes, gear position is determined by the position of the shift valves on the transmission, not the position of the ERC levers. When using the joystick or while in Skyhook, the computer moves the transmission in and out of gear even though the handles are in neutral.

Basic Joystick Operation

The joystick offers precise, intuitive control of your boat during low speed and docking maneuvers. The joystick translates the movement of the joystick into similar movement in the boat. Engine speed is limited in this mode to prevent unacceptable boat dynamics during maneuvers.
While operation with the joystick is easy to learn, we recommend that you drive the boat in the traditional way until you can spend time in an open area free of obstructions and traffic to learn how your boat responds to inputs. Further, we recommend that you occasionally practice maneuvering in the traditional way to maintain your traditional drive docking skills in case joystick control is temporarily not available.
Refer to Section 2—Maneuvering with the Joystick, for complete information concerning joystick operation.

Electrical System Overload Protection

If an electrical overload occurs, a fuse or a circuit breaker opens. Find and correct the cause for the electrical overload before replacing the fuse or resetting the circuit breaker.
NOTE: In an emergency, when you must operate the engine and cannot locate or correct the cause for the electrical overload (high current draw), turn off or disconnect all the accessories connected to the engine and instrumentation wiring. Reset the circuit breaker or replace the fuse. If the circuit remains open, the electrical overload has not been eliminated. Contact your Cummins MerCruiser Diesel Authorized Repair Facility to check the electrical system.

Circuit breakers and fuses provide protection for the electrical system as indicated. The circuit breakers and fuses are located in various locations throughout the boat. Have your dealer show you the location and identify the circuit that they protect.
After finding and correcting the cause of the overload, reset the circuit breaker by pressing the reset button.
VESSEL INTERFACE PANEL (VIP) OVERLOAD PROTECTION
The Vessel Interface Panel (VIP) contains six circuit breakers that help protect the transmission harness, engine harness, vessel sensor harness, and helm harness.

OVERLOAD PROTECTION FOR THE DC VOLTAGE REGULATOR SYSTEM, IF EQUIPPED
If the vessel is equipped with a 24‑volt system, a DC voltage regulator is required to supply 12‑volt power to the VIP and the other 12‑volt circuits. The power package manufacturer provides a protective fuse for the 24‑volt DC to 12‑volt DC voltage regulator system, if equipped. The spade‑style, in‑line fuse is located in the harness between the voltage regulator and the 24‑volt battery system. The fuse protects the wiring and the regulator against overloads.

The boat manufacturer may replace the fuse and holder with a circuit breaker. Have your boat manufacturer or dealer show you the location and identify the fuse or circuit breaker for your reference.
OVERLOAD PROTECTION FOR OTHER CIRCUITS
Other circuits may be protected by circuit breakers or fuses installed by the boat manufacturer and can vary in appearance and location.
For example, the MerCathode system has a 20‑amp in‑line fuse in the wire that connects from the positive (+) battery terminal to the positive (+) terminal on the controller. If the fuse is defective (open), the system will not operate, resulting in a loss of corrosion protection. Have your dealer show you the location of and service procedures for the fuse.
Ask your dealer for the location and operation instructions of all overload protection devices.

Galvanic Isolator and Monitor

These power packages feature anodes as standard equipment to help protect them from galvanic corrosion under moderate conditions. The MerCathode System and sacrificial anodes provide corrosion protection under normal usage.
Boats connected to AC shore power require additional protection to prevent destructive low‑voltage galvanic currents from passing through the shore‑power ground wire. A Quicksilver Galvanic Isolator or equivalent isolation device is recommended to block the passage of these currents while providing a path to ground for dangerous fault (shock) currents.
IMPORTANT: If AC shore power is not isolated from boat ground, the MerCathode System and anodes may be unable to handle the increased galvanic corrosion potential.

Section 2 - Getting to Know Your Power Package
41272
A Quicksilver Galvanic Isolator kit includes an audio and visual monitor to alert you to faults that occur. The monitor is a microprocessor controlled, solid state device that will test the integrity of the Quicksilver Galvanic Isolator and the safety grounding lead. This device will also supply impressed current to the drive to aid in corrosion protection.
WARNING
!
Improperly conducted AC shore power is an electric shock hazard that can result in damage and injury. The AC grounding conductor green wire must be connected between the boats electrical system and the shore power connection in order to provide a path for fault current and to assist the MerCathode in preventing galvanic corrosion on drive components. Install a galvanic isolator or similar isolation device in the AC shore power system in the vessel. Consult a qualified marine electrician for more information.
IMPORTANT: If the Galvanic Isolator alarm sounds and the monitor will not respond to the reset button, AC fault current may be present and the shore power safety grounding conductor circuit to shore may be an open circuit. Disconnect shore power immediately.
Refer to Troubleshooting—Galvanic Isolator for an explanation of the conditions or faults that may be displayed by the monitor.
Galvanic Isolator Monitor and conditions
NOTE: If your vessel is equipped with a galvanic isolator from a manufacturer other than Quicksilver, refer to the instructions provided by the manufacturers.

Safe Boating Suggestions

In order to safely enjoy the waterways, familiarize yourself with local and all other governmental boating regulations and restrictions, and also consider the following suggestions.
Know and obey all nautical rules and laws of the waterways. Cummins MerCruiser Diesel strongly recommends that all powerboat operators complete
a boating safety course. Courses are offered in the U.S.A. by the U.S. Coast Guard Auxiliary, the Power Squadron, the Red Cross, and your state or provincial boating law enforcement agency. Inquiries may be made to the Boating Hotline at 1‑800‑368‑5647 or the Boat U.S. Foundation at 1‑800‑336‑BOAT.
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 some suggestions of the types of safety equipment to carry when boating:
Approved fire extinguishers Paddle or oar Signal devices: flashlight, rockets or flares, flag, and whistle or horn
Section 3 - On the Water
Transistor radio Tools necessary for minor repairs First aid kit and instructions Anchor and extra anchor line Waterproof storage containers Manual bilge pump and extra drain plugs Spare operating equipment, batteries, bulbs, and fuses Drinking water Compass and map or chart of the area
Watch for 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. 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, wearable‑type life jacket (personal flotation device), correctly sized and readily accessible for every person aboard, plus a throwable cushion or ring. We strongly advise that everyone wear a life jacket at all times while in the boat.
Prepare other boat operators. Instruct at least one person aboard in the basics of starting and operating the engine and handling the boat 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). Know your boat’s operating and loading limitations. Know if your boat will float if full of water. When in doubt, contact your authorized Cummins MerCruiser Diesel dealer/distributor or the boat manufacturer.

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.
Page 26 90-866938081 MAY 2009
1. Example of desired air flow through the boat.
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.

Basic Boat Operation

Freezing Temperature and Cold Weather Operation

IMPORTANT: If the boat is operated during periods of freezing temperature, take precautions to prevent freezing damage to the power package. Damage caused by freezing is not covered by Cummins MerCruiser Diesel Limited Warranty.
NOTICE
Water trapped in the seawater section of the cooling system can cause corrosion or freeze damage. Drain the seawater section of the cooling system immediately after operation or before any length of storage in freezing temperatures. If the boat is in the water, keep the seacock closed until restarting the engine to prevent water from flowing back into the cooling system. If the boat is not fitted with a seacock, leave the water inlet hose disconnected and plugged.

mc79556-1
NOTE: As a precautionary measure, attach a tag to the key switch or steering wheel of the boat reminding the operator to open the seacock or unplug and reconnect the water inlet hose before starting the engine.
In order to operate the engine in temperatures of 0° C (32° F) or lower, observe the following instructions:
90-866938081 MAY 2009 Page 27
Section 3 - On the Water
21604
At the end of each daily operation, completely drain the seawater section of the cooling system to protect against damage by freezing.
At the end of each daily operation, drain the water from the water separator, if equipped. Fill the fuel tank at end of daily operation to prevent condensation.
Use the required permanent‑type antifreeze solution to protect components against damage by freezing.
Use proper cold weather lubrication oil; ensure that the crankcase contains a sufficient amount.
Make certain that the battery is of sufficient size and is fully charged. Check that all other electrical equipment is in optimum condition.
At temperatures of –20° C (–4° F) and below, use a coolant heater to improve cold starting.
If operating in arctic temperatures of –29° C (–20° F) or lower, consult your Cummins MerCruiser Diesel Authorized Repair Facility for information about special cold weather equipment and precautions.
See Section 6 for cold weather or extended storage related information.

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, a bilge pump, or both a drain plug and a bilge pump. Install the drain plug and check the operation of the bilge pump, if equipped, before putting the boat in the water.
Check these items on a regular basis to ensure that the level of water 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 Cummins MerCruiser Diesel Limited Warranty.

Protecting People in the Water

WHILE THE BOAT IS MOVING
A person in the water may find it very difficult 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.
Page 28 90-866938081 MAY 2009
WHILE THE BOAT IS STATIONARY
27301
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 engines before allowing people to swim or be in the water near your boat.
Do not allow people to swim around the boat with the Skyhook Electronic Anchor engaged. The Skyhook Electronic Anchor causes the drives to move and the propellers to turn without notice. Having the engines in neutral does not protect the swimmers. Swimmers in the area of the propellers are at risk of getting injured.

Wave and Wake Jumping

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.
WARNING
!
WARNING
!
Section 3 - On the Water
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.

Impact with Underwater Hazards

Reduce speed and proceed with caution whenever you are driving a boat in shallow water or in areas where the waters are suspected of having floating or underwater obstacles that could be struck by the underwater drive components, skegs, or the boat bottom.
mc79680-1
90-866938081 MAY 2009 Page 29
Section 3 - On the Water
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, reduce boat speed to a minimum.

Keep in mind that one of the most important things you can do to help reduce injury or impact damage in these situations is control the boat 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 systems for any broken or loose parts, and the hull for any damage. If damage is present or suspected, the power package should be taken to an Authorized Cummins MerCruiser Diesel Repair Facility for a thorough inspection and any necessary repair.
The boat should be checked for hull fractures, transom fractures, and water leaks.

of the boat.
WARNING
!
Operating a boat with impact damage can result in product damage, serious injury, or death. If the boat experiences an impact, have an Authorized Cummins MerCruiser Diesel Repair Facility inspect the vessel and power package and perform repairs as necessary.
Operating with damaged underwater drive components 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.

Zeus Drive Impact Protection

IMPORTANT: Although the design of the Zeus drive provides some impact protection, no design can ensure total protection from impact damage under all conditions.
The Zeus drive has some impact protection by design, since the drive is mounted in a tunnel above the bottom of the hull. If the drive strikes a floating or submerged object while the boat is moving, the skeg is designed to break away, absorbing some of the impact and possibly reducing damage to the propellers and the exposed lower part of the drive. In extreme cases, large fixed or floating objects struck by the skeg and the exposed lower part of the drive may cause the lower part of the drive to shear off. This shearing off of the lower part of the drive is a design feature to protect the hull and drive system.
NOTE: If the lower part of the drive shears off due to a severe impact, make immediate note of the GPS location to assist in recovery efforts. If recovery of the damaged parts of the drive is possible, return the damaged parts to your Authorized Cummins MerCruiser Diesel Repair Facility for possible repair and reuse.
If an impact occurs and damage is present or suspected, if the boat does not respond as it should, or if water is present in the gear lube monitor bottle, have your boat inspected at the nearest Authorized Cummins MerCruiser Diesel Repair Facility.
Operating in reverse gear offers less impact protection. 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.
Page 30 90-866938081 MAY 2009

Zeus Drive Alignment

The Zeus Drives are aligned by the boat manufacturer, and must not be adjusted by anyone other than your Cummins MerCruiser Diesel Authorized Service and Repair Facility. The Zeus drives automatically recalibrate to this setting at each startup. The drives do not need to be re‑aligned under normal use.

Conditions Affecting Boat Operation

Weight Distribution (Passengers and Gear) Inside the Boat

Shifting weight to the rear (stern):
Causes the bow to bounce in choppy water.
Increases the danger of a following wave splashing into the boat when coming off
plane.
Can cause the boat to porpoise at extremes. Shifting weight to the front (bow):
Improves ease of planing.
Improves rough water ride.
Can cause the boat to veer back and forth (bow steer) at extremes.
Section 3 - On the Water

Bottom Of Boat

Cavitation

Ventilation

To maintain maximum speed, the boat bottom should be:
Clean and free of barnacles and marine growth.
Straight and smooth (fore and aft). Marine vegetation can accumulate when the boat is docked. Remove this growth before
operation; it can clog the water inlets and outlets, causing the engine to overheat.
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 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:
A missing propeller diffuser ring.
A damaged propeller or gear housing, which allows exhaust gases to escape between
propeller and gear housing.

Propeller Selection

IMPORTANT: The installed propellers must allow the engine to reach engine Rated Speed (RPM) with the boat fully loaded and with all customer stores on board. With the boat less than fully loaded the engines should reach engine Rated Speed (RPM) with less than a 100% load. Use the VesselView display to verify engine RPM and percent load.
90-866938081 MAY 2009 Page 31
Section 3 - On the Water
It is the responsibility of the boat manufacturer or the selling dealer to equip the power package with the correct propellers. Refer to the engine Information Data Tag located on the engine for the specified engine Rated Speed (RPM). Information for the location of the engine data tag can be found in the engine owners manual.
If full throttle engine RPM is below the engine Rated Speed (RPM), the propellers will have to be changed to prevent loss of performance and possible engine damage.
After initial propeller selection, certain issues may require a propeller with a lower pitch. They include:
Operating with increased load (additional passengers or gear).
Shifting the center of gravity of the vessel.
The addition of towers or canvas.
Fouling of the hull and running gear.
High ambient temperatures.
Operating at high elevation.
It is the responsibility of the boat owner to ensure that the correct propellers are installed at delivery and maintained over the life of the boat. Because of the many variables of boat design, only testing will determine the best propeller for a particular boat. If the engine is not able to reach the engine Rated Speed (RPM), contact your boat builder, boat dealer, or an Authorized Cummins MerCruiser Diesel Repair Facility for assistance in propeller selection. A list of propellers for the Zeus drive can be located in the Zeus drive parts manual. Refer to the Zeus drive Mercury Parts Manual—90-879150112.

Getting Started

Break‑In Period (New or With Replacement Gears)
Always perform these procedures on new drive units. This break‑in procedure allows the proper seating of drive unit gears and related components, which greatly reduces the likelihood of problems.
Avoid full throttle starts.
Do not operate at any one constant speed for extended periods of time.
Do not exceed 75% of full throttle during the first 5 hours. During the next 5 hours, operate at intermittent full throttle.
Shift the drive into forward gear a minimum of 10 times during break‑in, with run‑in time at moderate RPM after each shift.
After the first 25 hours and not to exceed 30 hours, change the transmission fluid and filter including the transmission fluid in the drop box, if equipped.
After the first 25 hours and not to exceed 30 hours, change the gear lube in the drive including the gear lube in the gear lube monitor.

DC Voltage Regulator Switch, If Equipped

If the vessel is equipped with a 24‑volt system, a DC voltage regulator is required to supply 12‑volt power to the VIP and the other 12‑volt circuits. To allow the regulator to be turned on and off a switch is provided by the boat manufacturer. The switch is on a separate circuit.
Switching the power on provides regulated power to the VIP and other 12‑volt circuits to allow the vessel to start. Switching the DC voltage regulator off prevents the regulator from drawing power when the vessel is not operated.
Have your manufacturer or dealer show you the location and identify the DC voltage regulator switch for reference.

Traditional Maneuvering with Steering and Thrust

You can maneuver your Zeus‑equipped vessel much like a traditional inboard boat. However, the Zeus 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 Zeus 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. Different from traditional boats, to tighten the turn, you can increase power to the inside drive.
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
1. To turn the boat in tight turns at low speeds, turn the wheel in the direction of the turn.
2. To increase the turn rate of the boat after the wheel is completely turned, you may increase the power to the inside drive.
Page 38 90-866938081 MAY 2009
TO SPIN THE BOAT ON ITS AXIS AT LOW SPEEDS
25911
1. Center the steering wheel.
2. To spin to the right, place the starboard engine in reverse and the port engine in
forward.
3. To spin to the left, place the port engine in reverse and the starboard engine in
forward.
4. To increase the rate of turn, simultaneously adjust each ERC lever for more throttle.

Maneuvering with the Joystick

The joystick provides single lever interface to maneuver the vessel. Operating the vessel with the joystick is well suited for close quarter operations and when docking. The joystick causes the control system to independently control each pod angle and thrust to move or rotate the boat in a desired direction. For example, if you move the joystick sideways, the control system commands the boat in the sideways direction.
The joystick gives three axis control: fore and aft, port and starboard, and rotational, or any combination thereof. For example, moving the joystick to port causes the boat to move sideways to port. Rotating the joystick causes the boat to rotate around its center. You can move and rotate the joystick at the same time, allowing for very intricate movements for maneuvering in tight quarters.
The control system automatically attempts to dampen bow and stern swinging (referred to as yaw) during joystick operation. An on‑board sensor measures the yaw rate of the boat and actively counteracts the yaw motion of the boat. Factors, such as wind, water conditions or vessel loading, may act upon the vessel beyond the systems capability to correct yaw. Manual yaw correction may be required when commanding the boat in the fore and aft, port and starboard, or diagonal directions. To correct for unintended yaw during any maneuver just rotate the joystick in the direction the bow is desired to rotate.
The following table gives some limited examples of the basic responses to inputs from the joystick. The joystick is proportional, which means that the farther from the center the joystick is moved, the more thrust is applied to the boat in that direction.
To maneuver the boat with the joystick:
1. Move both electronic remote control (ERC) levers to the neutral position.
2. 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.

Trim Tabs

AUTOMATIC CONTROL
The Zeus drive comes equipped with an automatic trim tab control feature that operates through the vessel control system to provide basic performance and efficiency improvements under normal conditions.
The automatic trim tab control feature can be engaged (turned on) or disengaged (turned off). To engage the feature, press the "AUTO" trim tab button once. The trim tabs will automatically adjust as the speed of the boat is changed. Pressing it again will disengage the feature.
With the automatic trim tab control feature engaged the port and starboard trim tab switches can be used to adjust the tabs (offset) for natural conditions that affect the attitude of the boat. This setting of the trim tab offset continues until the automatic control feature is disengaged and engaged again or when the key switch is cycled (turned off and on).

Section 3 - On the Water
Manual trim tab control is available to allow trim tab adjustment when not using the automatic trim tab control feature. See Manual Control.
NOTE: The port or starboard manual trim tab rocker switches allow some control of the attitude of the vessel. As an example, to achieve a port bow down attitude, you may press the port bow down rocker switch to deploy the trim tab on the starboard drive and provide the requested vessel attitude adjustment.
MANUAL CONTROL
To manually control or adjust the offset of the trim tabs for your conditions, use the individual port or starboard trim tab switches as needed. Manually adjusted trim tabs will stay in the position set by the operator until the key switch is cycled off and on or the "AUTO" button is pressed. If the "AUTO" button is pressed, the automatic trim tab control feature is engaged and the trim tabs move to a position based on boat speed. See Automatic Control.
NOTE: When controlled manually the trim tabs do not move during acceleration unless the operator presses the trim tab buttons.
USING TRIM TAB OFFSET
Automatic or manual control of trim tab offset could be beneficial in the following conditions.

not run with the bow too far down. For the best performance as the boat comes on plane in manual control, the port and starboard trim tabs must be adjusted up so the boat does not run with the bow too far down. In automatic control, the trim tabs can be adjusted (offset) with the port and starboard trim tab switches for best performance when the boat conditions are temporarily outside the normal operating conditions.
To avoid an uncomfortable, jarring ride in certain sea conditions, adjust the trim tabs using either automatic control or manual control. As the wave throws the bow up trim tabs dampen the boat's reaction, leveling and smoothing the ride. In a following sea, put the trim tabs up. This allows the bow to lift, offsetting the waves, which lift the stern. In milder water some boats gently porpoise. Lower the trim tabs, a little at a time, until the lope disappears.
A boat list (leaning to port or starboard) can be caused by unbalanced load or several sea and weather conditions. Using the port or starboard trim tab switches, individual trim tab adjustments can be made in automatic control or manual control to correct a list.

Helm Transfer

Some boats are designed to allow control of the vessel from more than one location. These locations are commonly referred to as helms or stations. Helm transfer is a term used to describe the method of transferring control from one helm (or station) to another helm.
Avoid serious injury or death from loss of boat control. The boat operator should never leave the active station while engine is in gear. Helm transfer should only be attempted while both stations are manned. One‑person helm transfer should only be performed while engine is in neutral.
The helm transfer function allows the boat operator to select which helm is in control of the vessel. Before a transfer can be initiated the ERC levers at the active helm and at the helm intended for the transfer must be in the neutral position.
NOTE: If you attempt to transfer helm control when the ERC levers are not in neutral, a beep will sound and the helm transfer will not succeed until the levers at the helms are moved to neutral and transfer is requested again.
Some fault codes may appear on VesselView if other control or navigation functions are attempted after the helm transfer procedure is started. To remove the fault codes it may be necessary to cycle the key switch off and on, and then restart the helm transfer procedure. Ensure that other control and navigation inputs are performed after helm transfer is complete to avoid setting fault codes.
WARNING
!
The ERC levers must be in neutral to perform a helm transfer. While in neutral your vessel could drift and collide with objects nearby resulting in damage. Keep an adequate look out while performing the helm transfer.
To avoid damage, use extra care when attempting a helm transfer while the vessel is close to docks, piers, or other fixed items or when near other vessels.

Requesting Helm Transfer

NOTE: Any movement of the joystick or ERC levers after pressing the "TRANSFER" button terminates the helm transfer request. A single beep sounds and the transfer button light turns off signaling the end of the transfer request.
To request the transfer of vessel control from one helm to another:
1. At the helm you are requesting be made active and with the ERC levers in neutral, press the "TRANSFER" button one time. After the "TRANSFER" button is pressed, the transfer button light turns on and one beep will sound confirming the impending transfer.
NOTICE
"TRANSFER" button
Page 50 90-866938081 MAY 2009
NOTE: If the ERC levers at the helms are not in neutral, the neutral lights will flash. Move all the ERC levers to neutral and the neutral light should then be on.
2. With the "TRANSFER" button light and neutral light on, press the "TRANSFER" button
a second time to complete the helm transfer.
3. When the helm transfer is complete, another beep sounds and the transfer button light
turns off.
NOTE: If the helm transfer is not completed in ten seconds the request is automatically cancelled and a double beep sounds. Control will remain at the existing active helm. Press the "TRANSFER" button again to restart helm transfer.
4. The helm where the transfer request was initiated is now active and controls the
vessel.

Helm Transfer and Precision Pilot

Transferring control from an active helm to an inactive helm (from one station to another station) affects the functionality of Precision Pilot modes. Some of the affects are listed.
Auto Heading mode is disengaged when the ERC levers are moved to neutral for helm
transfer. You must re‑engage Auto Heading at the newly active helm.
Requesting a helm transfer causes Pilot to go to Standby mode. You will need to input
information at the new helm in control.
If engaged, Skyhook will disengage when the "TRANSFER" button is pressed the
second time. You must engage Skyhook at the the newly active helm.
The Resume feature for Auto Heading does not transfer automatically. After engaging
the previous Auto Heading course at the newly active helm, the resume feature works the same as at any active station.
In Track Waypoint mode the control of the route and display of route data on your chart
plotter does not automatically transfer to the chart plotter at the requested helm. You must turn on the chart plotter at the newly active helm, input the waypoint or waypoint route to be tracked, and re‑engage Track Waypoint.

Precision Pilot

Precision Pilot Trackpad Features

GENERAL INFORMATION
Precision Pilot trackpad features includes:
Precision Pilot (or Pilot) functions are controlled through the Pilot trackpad only.
Pilot screens are located under the Environment chapter of VesselView.
The "TURN" buttons provide a 10° course correction for each press to the port or
starboard.
The "AUTO HEADING", "TRACK WAYPOINT", and "WAYPOINT SEQUENCE"
buttons engage automatic course and heading modes.
The steering wheel feels locked into a detent when Auto Heading or Track Waypoint
are engaged. Manually overcoming the detent force of the steering wheel automatically puts Pilot into Standby mode.
STANDBY
The elements of the Standby screen are:
In standby mode, the display shows a digital compass value and the angle of the

Skyhook (If Equipped)

Your vessel may be equipped with a station keeping feature called Skyhook. Skyhook automatically maintains the heading and position of the boat within about 3 meters (10 feet) of a set position. The control system for Skyhook uses GPS and compass heading information to automatically control shift, throttle and steering to keep the boat in approximately one position.
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.
To unlock and be able to use this feature you will have to contact your Authorized Cummins MerCruiser Diesel Repair Facility.
when that button light is off, the light turns on
90-866938081 MAY 2009 Page 53
Section 3 - On the Water
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.
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.
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 no one is in the water near the boat and to make sure 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
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
The capability of Skyhook to maintain the position of the boat in a current is dependent on the characteristics of the boat. 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

platform, and to be alert for any sudden shifts in the boats position.
from the water.
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 continues to operate through a GPS signal outage for up to 10 seconds, but automatically 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 Precision Pilot keypad 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.
Page 54 90-866938081 MAY 2009
Skyhook performance is largely dictated by the performance of the onboard Zeus GPS
33798
8M0034159

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, allowing for more accurate positioning of your GPS. When WAAS is not available, the performance of the system maintains the boat within 20 meters (60 feet) of the desired position.
ENGAGING (ACTIVATING) SKYHOOK
IMPORTANT: Activities in the water near the vessel while Skyhook is engaged may result in injury. The Captain (or operator) and passengers should read and observe the warning labels on the boat before Skyhook is engaged.
Section 3 - On the Water
Label adjacent to the Precision Pilot trackpad
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. For replacement labels, contact the manufacturer of your boat, your Cummins distributor, or an Authorized Cummins MerCruiser Diesel Repair Facility.
1. Move the ERC levers to neutral and bring the boat to a stop. Skyhook will not engage
until the boat is in neutral and at a speed slow enough for safe engagement.
2. 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.
3. Check to see no one is on the swim platform, or in the water anywhere near the boat.

In Skyhook mode VesselView displays a special Skyhook screen. The elements of the Skyhook screen are:
RPM of the engines.
The rotation angle of the boat icon shows the yaw of the boat relative to its position
when Skyhook was first engaged.
The horizontal and vertical displacement of the vessel from the cross hairs is
proportional to the position error reported by the GPS.
Each gradation of color in the circular target on the VesselView screen is equivalent to
5 meters of error. If the boat exceeds 20 meters of error, then the boat is located at the edge of the circle. The boat continues to try to correct until Skyhook is disengaged.

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.
Track Waypoint allows the boat to automatically navigate to a specific waypoint or sequence of waypoints, called a waypoint route. This feature is intended for use in open waters, free from obstructions above and below the waterline.
When the Track Waypoint feature is activated and the boat is in operation:
The helm must never be unattended. The feature is not designed to allow unattended operation of the vessel.
The operator must remain at the helm at all times.
Page 62 90-866938081 MAY 2009
It must not be used as the sole source of navigation. IMPORTANT: Track Waypoint can only be used with chart plotters approved by CMD. Waypoint data needs to be provided to VesselView by a third party chart plotter. Refer to
your chart plotter's user manual for details. The accuracy of the feature can be affected by environmental conditions and incorrect
use. Observe the following information when using the Track Waypoint and Waypoint Sequencing feature.

Contingent Operations

Steering—Emergency Alternative Method

If the electronic steering wheel ceases to operate, the engine throttle handles (ERC handles), trim tabs, and the vessel joystick should still operate. Engine throttles and trim tabs can be used as an emergency alternative for steering in open water where there are no objects or other vessels in close vicinity.
Page 68 90-866938081 MAY 2009
To maintain steering and course heading, closely observe the amount of engine speed used with each throttle handle. Trim tabs can be adjusted to assist in steering the vessel. An operator should regularly practice steering the vessel in this manner to be familiar with using their vessel's throttles and trim tabs for steering.
The joystick can be used as an alternative method of steering when operating the vessel in close vicinity of objects, docks, and other vessels. Engine RPM is limited with joystick operation.

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 steering wheel will be monitored by the port control system.
However, if only the port side is operational, or only the port key switch is in the on position, the steering wheel will not have end stops provided by the force feedback system. In this case, the drive will always turn in the direction that the steering wheel is being rotated until the mechanical limits of the drive are reached. If there is damage to the port electrical system, the steering wheel will operate normally with complete force feedback and end stops.
The boat can operate as a single‑engine vessel. Note that joystick and station keeping are not available in this condition. However, Zeus features redundant AutoPilot systems, so Auto Heading and Track Waypoint mode are still available during single‑engine operation.
Section 3 - On the Water

Gear Engagement—Emergency Procedure

If a transmission or electrical system is damaged or has experienced a condition resulting in a fault such that a transmission does not respond to the helm controls, it is possible to manually engage a gear. In an emergency you can manually place a transmission into gear by using a suitable wrench to actuate the appropriate gear shifting solenoid.
Note the following:
It is better to use one drive that works properly than locking and operating the drive that
is not functioning properly. This procedure is for when both drives are not responding to helm control.
Auto Heading and Track Waypoint will work when emergency gear engagement is in
use.
Moving the ERC handle into reverse stops the engine.
Locking the transmission in gear using the emergency procedure renders the helm’s shifting control inoperable. Drive carefully with the gear lock engaged. To shift out of gear, turn the key switch to "OFF."
1. Determine the transmission that is not engaging a gear.
2. Stop the engines and remove the key from the key switch.
CAUTION
!
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.
3. Remove the drive cover of the affected transmission. Refer to Section 5—The Drive

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.
7. Ensure that the area around the propellers is clear before starting the engine since the propeller will be turning whenever the engine is operating.
IMPORTANT: The engine does not start with the ERC lever in gear, even though the drive is manually engaged in a gear.
8. When you are ready to start the engine, position the ERC lever in neutral gear before turning the key switch to the start position.
NOTE: Due to the extra load of turning the drive gears and propeller, the starter may turn slower when starting the engine connected to the drive in the emergency setting.
9. Use extra care and caution when operating your boat in this emergency mode. On the drive with the manually engaged gear, you must turn that engine off to stop the propeller from turning or providing thrust.
NOTE: Putting the drive with the gear manually engaged into reverse stops the engine.
10. Immediately take your boat to an Authorized Cummins MerCruiser Diesel Repair Facility and inform them that the drive gear has been manually engaged.

Steering and Trim—Manual Override

The steering and trim system operate using a hydraulic manifold fitted with control valves. If a malfunction occurs in the manifold for the steering and trim system, VesselView should display a fault code. The steering actuator, trim cylinder, or both may not respond to helm control resulting in the loss of normal steering or trim control.

Product Responsibilities

Owner and 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 a Cummins MerCruiser Diesel Authorized Repair Facility for a periodic checkup.
Normal maintenance service and replacement parts are the responsibility of the owner or 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 Cummins MerCruiser Diesel Authorized Repair Facility for service aids.

Dealer Responsibilities

In general, a dealer's responsibilities to the customer include predelivery inspection and preparation such as:
Make certain that the power package and other equipment are in proper operating condition before delivery.
Make all necessary adjustments for maximum efficiency.
Explain and demonstrate the operation of the power package and boat.
Provide you with a copy of a Predelivery Inspection Checklist.
Fill out the Warranty Registration Card completely and mail it to the factory immediately upon sale of the new product. All power packages must be registered for warranty purposes.
Do‑It‑Yourself Maintenance Suggestions
Present‑day marine equipment, such as your Cummins MerCruiser Diesel power package, are highly technical pieces of machinery. 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 do not 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 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 local Cummins MerCruiser Diesel Authorized Repair Facility is there to service your power package. They have qualified factory‑trained mechanics.

Section 5 - Maintenance
It is recommended you have the Cummins MerCruiser Diesel Authorized Repair Facility 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.
Inspect your power package at regular intervals to help maintain top operating performance and avoid potential problems before they occur. Check the entire power package carefully, including all accessible engine and drive parts. For engine inspection information, refer to the appropriate Cummins Marine Engine Operation and Maintenance Manual .
1. Check for loose, damaged, or missing parts, hoses, and clamps. Tighten or replace as
necessary.
2. Check electrical connections and leads for damage.
3. Remove and inspect the propellers. If nicked, bent, or cracked, contact your Cummins
MerCruiser Diesel Authorized Repair Facility.
4. Repair nicks and corrosion damage on the power package exterior finish. Contact your
Cummins MerCruiser Diesel Authorized Repair Facility.
While inspecting the power package and drive, certain components can be damaged by the weight of an individual and must not be used as a step. Decals on top of the drive components indicate where no step is allowed. Do not step on components with a decal.
Decal placed where no step is allowed
The Zeus drive cover, if equipped, protects and separates some components after the drive is installed. The drive cover provides added protection against damage to the hoses and other components as a result of mechanical hose abrasion during operation or damage to the hoses, such as being stepped on during service or maintenance. If equipped, keep the drive cover installed except when removed for service.

Drive Gear Lube

Drive Gear Lubrication

Discharge of oil, coolant, or other engine/drive fluids into the environment is restricted by law. Use caution not to spill oil, coolant, or other fluids into the environment when using or servicing your boat. Be aware of the local restrictions governing the disposal or recycling of waste, and contain and dispose of fluids as required.

NOTICE
The drive gear lubrication system includes a translucent white monitor the level of the drive gear lubricant (lube). The monitor includes a switch that can detect a low level of gear lubricant and set an audio or visual alarm.
The Checking and Filling procedures as provided are for situations where the gear lubricant level in the monitor is low but lubricant is visible. Filling the monitor to the specified level whenever lubricant is still visible in the monitor is correct.
In some events, such as a seal leaking, the gear lubricant level may have dropped low enough that no lubricant is visible in the monitor. In these situations the operator should have received an audible or visual alarm of a low gear lubricant level. If there has been an audible or visual alarm for low gear lubricant level and the monitor is found empty, filling the system through the gear lube monitor (when no lubricant is visible in the monitor) is not correct and requires additional steps as outlined in the Event Summary table.
IMPORTANT: If the gear lube monitor is empty, air may be trapped in the drive lubrication system by attempting to fill the monitor through the opening in the monitor. Trapped air may cause the lubricant level to appear correct in the monitor but still be low or insufficient in the system.
The steps for correct maintenance of the drive gear lubrication level can be summarized by the following table:

Event Task
Remove the drive side cover. Pressure fill the drive unit through the steering actuator Monitor empty and with an alarm
until the gear lube appears in the gear lube monitor at the "COLD FILL LEVEL" line.
Refer to the appropriate steps in Changing—With the Boat in the Water and fill the
drive through the steering actuator.
IMPORTANT: The gear lube level in the gear lube monitor rises and falls during drive operation; always check the gear lube level when the drive is cool and the engine is shut down.
NOTE: It is normal to add a small amount of gear lube between change intervals.
IMPORTANT: If the gear lube level is below the "COLD FILL LEVEL" line when checked (especially after the first couple of times the boat is operated for a long period) or if gear lube must be added frequently, there could be a lubricant loss, such as a seal leak. Leaks could result in a lack of lubrication that will damage the drive. Inspect the drive if lubricant loss occurs. Contact your Cummins MerCruiser Diesel Authorized Repair Facility.
1. On models equipped with a drive cover: a. Inspect the gear lube level in the monitor.
a - Port side cover b - Gear lube monitor c - Access cover
b. If necessary, remove the access cover from the drive cover.
a - Access cover b - Molded clip c - Indented‑edge
c. Remove the cap from the gear lube monitor.
2. To check the drive gear lube with the optional drive cover removed, refer to Removing the Drive Cover.

between the "COLD FILL LEVEL" (cold full line) and the "MAX OPERATING LEVEL" (hot full line).
"COLD FILL LEVEL" (cold full line)
"MAX OPERATING LEVEL" (hot full line)
IMPORTANT: If any water is visible at the bottom of the gear lube monitor or if the gear lube appears discolored, contact your Cummins MerCruiser Diesel Authorized Repair Facility immediately. These conditions may indicate a water leak in the drive.
4. If the level is lower than the "COLD FILL LEVEL" (cold full line), refer to Filling.
NOTE: The Premium Gear Lubricant used during the break‑in period is brown in color. The color of High Performance Gear Lube, used after break‑in, is blue. Do not mix the gear lubricants.
5. If the cap was removed, ensure that the gasket for the gear lube monitor cap is properly positioned and install the cap. Do not overtighten.
