Section 1 - Getting to Know the Joystick Piloting System

Features and Controls

Vessel Personality

Mercury Marine and your boatbuilder developed a vessel propulsion personality to ensure optimal performance of the joystick, steering, and autopilot under ideal conditions. As wind and current conditions change, user input will be required to compensate.

Changing engine performance, gear ratios, or propellers may affect the performance of the joystick as well as the top speed of the vessel. Changing any parameter from the original factory equipment and settings can have a negative effect on performance, and changes must not be made without first consulting the boat manufacturer and a Mercury product integration engineer.

The vessel propulsion personality is the property of the boat manufacturer. Changes or upgrades to the personality must be approved and distributed by the boat manufacturer. Mercury Marine will assist with software personality changes only at the request of the boat manufacturer.

Instrumentation

VesselView

There are several VesselView products available. VesselView will display all engine information, fault codes, vessel information, basic navigation data, and system information. When an operating system error or failure occurs, VesselView displays an alarm message.

VesselView may also be connected to other vessel systems such as GPS, generators, and chartplotters. This vessel integration allows the operator to monitor and control a wide range of vessel systems from a single display.

Refer to the VesselView operator's manual for more information.

VesselView 7

SmartCraft Digital Instruments

The SmartCraft instrument package augments the VesselView display. The instrument package may include:

• Tachometer

• Speedometer

• Engine coolant temperature

• Engine oil pressure

• Battery voltage

• Fuel consumption

Page 2 90-8M0099745 eng

MAY 2015

• Engine operating hours

The SmartCraft instrument package also aids in identifying fault codes associated with the engine audio warning system. The

SmartCraft instrument package displays critical engine alarm data and other potential problems on its LCD display.

For basic operation information on the SmartCraft instrument package and for details on the warning functions monitored by the system, refer to the manual provided with your gauge package.

System Link Digital Instruments

Some instrumentation packages include system link gauges that augment the information provided by VesselView or a

SmartCraft system tachometer and speedometer. The owner and operator should be familiar with all the instruments and their functions on the boat. Have your boat dealer explain the gauges and normal readings that appear on your boat.

The following digital instruments may be included with your power package.

Electronic Helm Steering

The electronic helm steering operates through electronic signals. We recommend that you drive carefully until you have a chance to explore the joystick piloting system's handling characteristics and boat's response in an open area clear of obstructions or other boat traffic. The electronic helm steering can provide a faster steering response than expected.

To confirm your steering range from lock‑to‑lock, ensure that the starboard engine key is on. The engines do not have to be running for this test. Steer to starboard until the wheel stops. This stop is electric and is driven by the electric motor attached to the steering wheel. Begin turning the wheel to port and count the number of turns until the wheel stops at the port lock. This is the number of turns the drives will move from full starboard (26°) to full port (–26°), with the center straight ahead position at zero (0) degrees.

You may experience times during which the electronic end stops of the wheel are not felt. This will happen when the starboard key is off, the starboard engine battery voltage is low, the 20‑amp circuit breaker (typically labeled Helm Main Power or similar) is tripped, or a steering wheel motor fault occurs. This loss of feedback will not result in loss of steering, however. The drives will still stop turning when the wheel reaches the hard‑over position at each lock.

The vessel personality developed by the boat manufacturer in partnership with Mercury Marine, determines the number of turns lock‑to‑lock. Typically, this is about 2‑1/2 turns of the wheel from lock‑to‑lock, resulting in full starboard to full port steering angle.

Section 1 - Getting to Know the Joystick Piloting System

Joystick—Basic Operation

The joystick offers intuitive control of your boat during low speed operation and docking maneuvers. Engine speed is limited to approximately 1700–2500 RPM in this mode, depending on vessel and propulsion application, to prevent excessive propeller wash or unacceptable boat dynamics during maneuvers. DOCK mode reduces this limited engine speed by approximately 30% and will be discussed more in the DOCK mode section. This RPM reduction may vary between engine models and horsepower.

Environmental conditions such as strong wind and current may require more thrust than what is listed previously. If more power is needed for vessel maneuvering, use the electronic remote control levers.

55918

Typical joystick location

Though joystick operation is easy and intuitive, you should avoid using it until you have the opportunity to become familiar with the vessel's handling characteristics while operating the vessel with the joystick in open water. Thereafter, you should occasionally practice operating without the joystick in case the joystick becomes inoperable.

Both engines must be running and both ERC levers must be in neutral for the joystick to operate.

Engine Guardian Strategy

IMPORTANT: Boat speed could be reduced to idle and may not respond to your throttle demands.

Engine Guardian Strategy is designed to help reduce the potential for engine damage by reducing engine power when a potential problem is detected by the PCM or SmartCraft system.

When the Guardian system detects a failure in the shift system or other abnormal condition, it will leave the shift actuator in the last known position. Therefore, if the drive is in gear and there is a fault, the drive remains in gear. Pulling the lanyard, activating the E‑stop switch, or turning the key to the off position and restarting the engine will result in the gear position returning to neutral. This allows you to continue to maneuver the vessel in forward gear and return to port.

Engine Guardian monitors:

• Engine oil pressure

• Coolant temperature

• Seawater pressure

• Engine overspeed

• Shift system

Should Engine Guardian engage on your vessel, your SmartCraft instrumentation will indicate this and advise you to reduce throttle if necessary. Engine Guardian may also reduce throttle for you if the situation requires it.

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

Premier Features (If Equipped)

Chartplotter Requirements

Many of the Premier features use information from the chartplotter to function. However, not every chartplotter has the quality of information needed to allow these features to work properly. The chartplotter on your boat has been selected from an approved list created and maintained by Mercury MerCruiser. These chartplotters use specific software to meet the stringent demands to function with the Premier system.

• All chartplotters on the vessel must be calibrated the same.

• All chartplotters on the vessel must have the arrival radius alarm set to no less than 0.05 nautical mile (0.06 mile).

• All chartplotters on the vessel must be capable of sharing waypoint data.

• Some chartplotter models require the turn transition distance to be set greater than the arrival alarm radius. For more information on the turn transition distance, refer to the appropriate chartplotter operation manual.

Page 4 90-8M0099745 eng

MAY 2015

Section 1 - Getting to Know the Joystick Piloting System

Poor quality or inaccurate information generated by unapproved chartplotters or software can cause the features to behave erratically, unexpectedly, or not function at all. Updating software to an unapproved version can also cause the system to not function correctly. See your dealer or call Mercury Customer Service for approved plotters, plotter settings, and compatible software in the event your chartplotter needs service.

VesselView Autopilot Screen

The VesselView autopilot screen displays:

• Steering angle of the drives when in standby mode

• A digital compass value of the current heading

• Three icons to indicate the currently selected response level

• Engine RPM

a Heading b Steering angle reference c Engine RPM d Response level

a c d

Trackpad Buttons with the Power Icon

The power icon located on the buttons for Skyhook, auto heading mode, and track waypoint mode indicate that the buttons can engage or disengage the autopilot function they perform.

If you press a button that has the power icon when that button light is on, the light turns off for that button and the standby light illuminates.

If you press a button that has the power icon when that button light is off, the light turns on for that button, a single beep sounds, and the active light illuminates, unless another mode is currently active. If another mode is currently active, press the button on the active mode to disengage it, then press the button for the new mode.

If you press a button with the power icon when that button light is off, the light turns on for that button, a single beep sounds, and the active light illuminates.

Autopilot Trackpad Lights

The autopilot trackpad includes lights to indicate when an autopilot mode is active (engaged) or in standby (disengaged). If the standby light is illuminated, then the autopilot is disengaged (off). If the active light is illuminated, then the autopilot is engaged

(on).

Pressing the button for auto heading, track waypoint, or Skyhook will engage that mode, turning on both its respective light and the active light.

Autopilot Modes

WARNING

Avoid serious injury or death. Inattentive boat operation can result in a collision with other watercraft, obstacles, swimmers, or underwater terrain. The autopilot navigates a preset course, and does not automatically respond to hazards in the vicinity of the boat. The operator must stay at the helm, ready to evade hazards and warn passengers of course changes.

The autopilot includes several modes that can steer your vessel to a specific compass heading or to destinations generated from a chartplotter and GPS unit. If using a device to generate course information, you must be familiar with the operation of that chartplotter and GPS unit before attempting to use the autopilot to steer your vessel. The autopilot does not control speed, only direction, and it cannot sense hazards to navigation. These automatic modes do not relieve the operator of the responsibility to stay at the helm and keep a vigilant lookout for other vessels, persons in the water, or hazards to navigation.

When using the autopilot with a chartplotter and a GPS unit to navigate along a series of waypoints (a route), be aware that the boat will not travel to the precise location of the waypoint before initiating a turn to the next waypoint. Your chartplotter establishes a zone called an arrival circle around the point, and the autopilot will announce arrival at the waypoint when the boat enters that zone.

Section 2 - On the Water

Getting Started

Starting the Engine

1. Place the remote control handle in neutral.

WARNING

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

2. Turn the ignition key to the RUN position.

NOTE: This power package is equipped with SmartStart and may have a push button for starting. Rather than holding the start button or key switch to start the engine and then releasing it when the engine starts, SmartStart completely controls the starting process. When the start button is pushed, the PCM signals the engine to start. If the engine does not start, the starting process times out after a few seconds or when the engine reaches 400 RPM. Attempting to start the engine with the engine already running will turn the engine off.

3. Turn the ignition key switch to the START position then release, or press the start/stop button and release. If the engine is cold, allow the engine to operate at idle for 6–10 minutes or until the engine temperature reaches 71° C (160° F) for closed cooling and 60° C (140° F) for standard cooling.

4. If the engine does not start after three attempts: a. Push the throttle only button and position the remote control handle or throttle lever to the 1/4 throttle position.

b. Turn the ignition key to START position then release, or press the start/stop button and release. Be prepared to quickly move the control handle to the idle position. Allow the engine idle RPM to stabilize before shifting.

NOTICE

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

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

6. Move the control handle with a firm, quick motion forward to shift to forward gear, or backward to shift to reverse. After shifting, advance the throttle to the desired setting.

Traditional Maneuvering with Steering and Thrust

You can maneuver your joystick piloting‑equipped vessel much like a traditional sterndrive boat. However, the joystick piloting 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 through independently articulating drives to produce more responsive turning of the vessel. The joystick piloting drive system features counterrotating propellers that do not produce any propsteer when accelerating or slowing down.

To Maneuver the Boat in Forward or Reverse

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

To Steer the Boat in Tight Turns at Low Speeds

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

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

To Spin the Boat at Low Speeds

• Turn the drives to straight forward.

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

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

• To increase the rate of turn, simultaneously adjust each ERC lever for more throttle. More reverse throttle will be needed to compensate for the forward drive.

Synchronizing Engines

Sync mode is an automatic engine‑synchronization feature that engages automatically at key‑up. Sync mode monitors the position of both ERC levers. If both the levers are within 10% of one another, all engines synchronize to the starboard engine's

RPM. The SmartCraft system will automatically disengage sync at the last 10% of the lever range to allow each engine the ability to reach the maximum available RPM. Sync mode cannot engage until its minimum RPM is met.

The indicator light on the sync button will be on when all engines are on. The light is yellow at idle and 95% of throttle and when the engines are not synchronized. The light turns red when the engines are synchronized.

51857

Sync button and light

VesselView shows an orange icon if the engines exceed an RPM difference of 10% of one another. The icon turns red when they synchronize. The icon turns off when sync mode is off.

To disengage sync mode:

1. Place the ERC levers into any detent.

2. Press SYNC. The sync light turns off.

To engage sync mode, press the sync button at any time.

Single Engine Operation

If an engine or steering system stops functioning during use, the remaining drive is electronically limited while turning inboard.

This prevents the drives from making contact with each other, since the active drive is unable to determine the position of the disabled drive. The boat is still operational, but maneuverability is decreased when turning toward the side that is not working.

Refer to the inboard drive angle limit in the following table. The drive is still capable of turning through its full range when turning away from the disabled drive. Use extra caution when one of the drives is disabled.

The limit may be greater than specified in the previous table depending on the propulsion personality and distance between the drives. Single engine operation should be intentionally experienced in order to become familiar with the limits of the vessel maneuverability.

IMPORTANT: Intentionally experiencing single engine operation for the first time should be conducted in an open area that is not congested with obstacles or other vessel traffic.

To experience single engine operation, proceed with the following:

1. Ensure the vessel is in an open area with a calm sea.

2. Turn off the engines.

3. Start the starboard engine only.

4. Shift the starboard engine into forward gear.

5. At idle, attempt to steer the vessel, noting how it maneuvers.

6. Advance the throttle slowly while attempting to steer the vessel. Note how it maneuvers.

7. After experiencing single engine operation at various different engine RPMs, shift the starboard engine into neutral.

8. Start the port engine to continue with normal vessel operations.

IMPORTANT: There are two possible conditions that can be encountered when experiencing single engine operation with the port engine running. 1) With the port engine running and the starboard engine key in the OFF position, you will not feel the steering wheel end stop feedback. 2) Turning the starboard engine key to the ON position will provide steering wheel end stop feedback.

Maneuvering with the Joystick

WARNING

A spinning propeller, a moving boat, or any solid device attached to the boat can cause serious injury or death to swimmers.

Stop the engine immediately whenever anyone in the water is near your boat.

NOTICE

The vessel personality that determines how a boat responds to joystick commands was created for typical boat loading and operation in ideal boating conditions. Variations in wind, current, and boat loading will have a substantial effect on the performance of joystick operations. For example, a boat that is loaded heavily to the bow will behave differently than a boat that is loaded heavily to the stern. The vessel personality cannot anticipate nor compensate for these variables. It is the operator's responsibility to make the necessary corrections by changing the loading of the boat or by performing additional maneuvers to track the desired path.

The joystick provides a single lever interface to maneuver the vessel. Operating the vessel with the joystick is well suited for close quarter and docking operations in most situations. You can move and rotate the joystick at the same time, allowing intricate movements in close quarters.

The computer control system automatically calculates the steering angle of each engine, the throttle level, and the proper gear to push or rotate the boat in a direction corresponding to a joystick movement or twist. For example, if you move the joystick sideways, the computer control system commands the engines to apply sideways thrust to the boat. Rotating the joystick prompts the computer to command forces that rotate the boat about its center.

The joystick is proportional, which means the greater distance from the center that the joystick is moved, the more thrust that is applied to move the boat in that direction. The available demand on the engine is limited while using the joystick.

For joystick control of the boat:

1. Both engines must be running for joystick to function.

2. For best control, trim all engines to the full‑down position and allow the auto trim function to adjust the engines to the optimal trim angle.

• If the engines are already trimmed down, the operator need not change the trim. The computer controlled system will automatically trim the engines up to the vessel propulsion personality predetermined angle when the joystick is engaged.

90-8M0099745 eng

MAY 2015 Page 13

Section 2 - On the Water

• If the engines are trimmed up, the operator should manually adjust the trim to full down, provided doing so does not create a hazard. The system will not automatically trim the engines down when the joystick is engaged.

•

For more details, refer to Auto Trim.

IMPORTANT: After joystick operation and before attempting to put the vessel on plane, the trim position must be set to an angle that allows for normal operation. The computer controlled system will not return the drives to the position they were at before the joystick was engaged.

3. Move all of the electronic remote control levers to neutral. For Zero Effort controls, shift into neutral and place the throttle levers at idle.

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

The following picture gives a limited example of the basic responses to inputs from the joystick, and should be used for reference only. The pictures show an approximate correlation between joystick inputs and the corresponding movement of the vessel. Exact maneuvers will require multiple joystick inputs and additional user corrections to maintain the maneuver.

NOTE: The joystick does not have detents. It can be positioned at any of the indicated arrows or anywhere in‑between.

Centering the Drives after Joystick Operation

Upon releasing the joystick, the drives will remain in their last commanded position, unless the last command was yaw (twisting the joystick). To center the drives, move the steering wheel or twist the joystick.

Moving the ERC Handles while in Joystick Mode

If the ERC handles are moved while the joystick is in operation, a noncritical fault will be set in the system. A six‑second intermittent beep will sound, an ERC override fault will be displayed on the VesselView, and the ERC will take command of the vessel from the joystick. Once the ERC handles are returned to neutral, the joystick can again assume control of the vessel.

Auto Trim

The Joystick Piloting system includes an auto trim feature that works with Skyhook station keeping and joystick operations. This feature will automatically trim the drives up or down to a position preset by the boat manufacturer.

Enabling Auto Trim

Auto trim is enabled whenever the ERC levers are moved into a gear and then back into neutral, or when the engines are started.

Auto Trim Up

When the operator assumes control of the vessel with the joystick, auto trim will raise any drive that is trimmed below the preset position to that preset position, provided that auto trim has been enabled as described above. Auto trim will similarly raise the drives when Skyhook is engaged. Once the drives have been trimmed up to the preset point, auto trim is disabled and can only be reenabled as described previously.

Page 14 90-8M0099745 eng

MAY 2015

Section 2 - On the Water

Auto Trim Down

When the operator assumes control of the vessel with the joystick and one or more drives is trimmed above the preset position, a pop‑up notice will appear on the VesselView display. Similarly, if Skyhook is engaged with one or more drives trimmed above the preset, the pop‑up will appear. This notice will disappear after 10 seconds, but the operator is provided a full 15 seconds during which to initiate the auto trim down function.

To initiate auto trim down, briefly press the trim all down button on the ERC or trim pad. Any drive trimmed above the preset position will be automatically trimmed down to the preset position. To halt the auto trim down of a particular drive, push either trim button (up or down) for that drive. To halt the auto trim down of all drives, push either trim all button.

IMPORTANT: The preset position for auto trim is accurate to ± 3°, meaning that auto trim in either direction can overshoot by as much as 3°. If one drive is auto trimmed up and the other drive is auto trimmed down, the drives may be trimmed differently by as much as 6°. This is not a malfunction.

To bring the drives to the same auto trim position:

1. With the engines off, but the key switches on, trim the drives to their full down position. Hold the trim button for an additional three seconds.

2. Start the engines.

3. Enable auto trim.

4. Engage the joystick or Skyhook. The drives will all auto trim up to the same position.

Skyhook Station Keeping

Your vessel is equipped with the Skyhook station keeping feature. This system uses global positioning system (GPS) technology and an electronic compass to automatically control shifting, throttling, and steering to maintain heading and approximate position. This feature can be helpful when waiting for space near a fuel dock, waiting for bridges to open, or when the water is too deep for an anchor.

Skyhook does not maintain an exact fixed position, but rather will hold the vessel in a fixed compass heading within an approximate area. The size of this area is affected by the accuracy of the global positioning satellite system, the satellite signal quality, the physical position of the satellites relative to the receiver, solar flares, and the proximity of the receiver on the vessel to large structures (for example, bridges or buildings) and trees. Under some of these conditions Skyhook may be affected enough that the system will disengage. The operator must remain at the helm whenever Skyhook is engaged and be vigilant for changing conditions such as the presence of other vessels or swimmers or the disengagement of Skyhook.

90-8M0099745 eng

MAY 2015 Page 15

Section 2 - On the Water

Under typical operating conditions, Skyhook is capable of holding the vessel within a radius of 10 m (30 ft). However, this distance may sometimes increase to a radius of 30 m (100 ft). Because Skyhook holds the boat in an approximate position, not a precise one, it can cause your boat to collide with other objects close to your boat and cause damage. Do not use Skyhook when your boat is close to a dock, piling, bridge, another vessel, or swimmer.

WARNING

Skyhook is an automatic system. Use of this system does not relieve the operator of the responsibility to remain at the helm and keep watch for changing conditions. The presence of swimmers or other vessels, or if Skyhook becomes disengaged, will require the operator to assume manual control of the vessel.

Important Safety Considerations

Activities in the water near the vessel while Skyhook is engaged may result in injury or death. The operator should read and observe the warning labels on the boat, and instruct passengers how Skyhook operates before using the feature.

Label near the autopilot trackpad

52820

52821

Label in the vicinity of the transom boarding area

IMPORTANT: If either of these labels cannot be located or are not legible, they must be replaced before engaging Skyhook.

For replacement labels, contact the manufacturer of your boat or a Mercury Marine authorized repair facility.

Before engaging (activating) Skyhook, the operator must:

1. Inform passengers how Skyhook operates, to stay out of the water and off the swim platform and boarding ladder, and to be alert for any sudden shifts in the boat position.

2. Inform passengers of any audible or visual warning systems that may be installed on the boat, and when they can expect them to be active.

3. Check to see that no one is near the back of the boat or anywhere in the water near the boat.

After engaging (activating) Skyhook, the operator must:

1. Remain at the helm and maintain a vigilant watch.

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

WARNING

A rotating propeller, a moving boat, or a device attached to a moving boat can cause serious injury or death 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.

Engaging Skyhook

Skyhook will not engage unless the joystick and control levers are in neutral.

Page 16 90-8M0099745 eng

MAY 2015

Section 2 - On the Water

1. Maneuver the boat to the desired position.

2. Ensure that the ERC levers are in neutral.

3. Confirm that the area around the boat is clear of swimmers and obstacles.

4. Press the Skyhook button.

NOTE: A double horn beep sounds if the Skyhook mode does not engage.

When the Skyhook button is pressed on the autopilot trackpad, VesselView will display the Skyhook warning pop‑up.

51861

After the warning pop‑up has been acknowledged, VesselView will display a Skyhook warning in the contextual area and show the gear positions in orange.

Disengaging Skyhook

Skyhook can be disengaged several different ways:

• Move the steering wheel.

• Press the Skyhook button on the autopilot trackpad.

• Move the joystick and return to the original neutral position.

• Move the ERC levers.

• Turn off one or more engines.

Skyhook does not automatically resume when the steering wheel, levers, or joystick are returned to their original position. The

Skyhook button must be pressed again to reengage the feature.

Using Skyhook

Skyhook system response will change with wind and current conditions. Familiarize yourself with how best to position your vessel regarding the speed and direction of wind and current. Practice with Skyhook to determine what works best for your vessel in various situations.

90-8M0099745 eng

MAY 2015 Page 17

Section 2 - On the Water

In extreme weather and sea conditions, Skyhook may not be able to maintain a vessel's heading and position. This is especially true if the vessel's heading is perpendicular to the wind or current. If the wind or current forces the vessel away from the position where Skyhook was set, Skyhook will start to turn the bow of the vessel back to the original set point. As the vessel is pushed further away, Skyhook will continue to rotate the bow to the set point until the bow eventually points directly at the set point.

• If at any time in this process Skyhook is able to overcome the conditions enough to hold a position, it will cease turning the bow.

• If the conditions lessen and Skyhook is able to maneuver the vessel back toward the original set point, Skyhook will rotate the bow back to the original heading as it maneuvers the vessel toward that set point.

• If the vessel is forced far enough away from the set point, Skyhook will notify the operator that it is not able to maintain position. Skyhook will continue to attempt to return to the set point, unless the operator assumes control of the vessel.

To minimize the effects of extreme conditions on the operation of Skyhook, Mercury Marine recommends adjusting the vessel's heading so that its bow (or for some vessels, its stern) faces into the wind or the current.

Skyhook can unexpectedly disengage due to a loss of engine power or GPS signal. If this happens Skyhook will sound an alarm, the engines will return to neutral, and the vessel will drift with the wind and current. You must be ready to take control of the helm at all times.

Response Settings

How aggressively the vessel reacts to programmed changes when in autopilot modes can be changed in VesselView by the operator. By default, the response is set at level 3. Press the response button once to identify the current setting. The response light will blink to indicate the current setting. Pressing the button within five seconds changes the response setting to the next sequential level.

Autopilot Modes

WARNING

NOTE: Moving the steering wheel will always override the autopilot, and the operator will assume control of the vessel. A slight resistance in the wheel gives the operator feedback that he is taking control from the autopilot. Shifting the electronic remote control (ERC) lever will also disable the autopilot mode.

When using the autopilot with a chartplotter and a GPS unit to navigate along a series of waypoints (a route), be aware that the boat will not travel to the precise location of the waypoint before initiating a turn to the next waypoint. Your chartplotter establishes a zone called an arrival circle around the waypoint, and the autopilot will announce arrival at the waypoint when the boat enters that zone.

Auto Heading

Auto heading allows the boat to automatically maintain a compass heading while the boat is underway.

Engaging Auto Heading

1. Ensure that both engines are running and in gear.

NOTE: Auto heading does not function with the ERC levers in neutral or reverse.

2. Steer the boat to the desired compass heading.

IMPORTANT: The previous heading can only be resumed within four minutes of the auto heading being disengaged by turning the wheel past the detent or if the vessel has been turned no more than 90°.

Press the resume button to resume the previous heading, if you turned the steering wheel and disengaged auto heading.

Disengaging Auto Heading

1. Disengage the auto heading mode with any of the following actions:

• Place the ERC handles for all engines in neutral. The auto heading light turns off and the standby light comes on.

• Turn the steering wheel beyond the electronic detent. The auto heading light turns off and the resume light comes on.

• Press the auto heading button on the autopilot trackpad. The auto heading light turns off and the standby light comes on.

4. If the standby light is on and the resume light is not, you cannot resume your course by pressing the resume button. Refer to To Resume a Heading. Press the auto heading button to fully exit the auto heading mode.

Track Waypoint

WARNING

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. Both engines must be running and in gear to operate in autopilot modes

The following illustration is an example of a waypoint route.

• Waypoints are shown in numbered squares within the arrival circle (a dashed‑line circle around the numbered square).

• A hazard is present between waypoints 1 and 2. If these waypoints are used for the route, the autopilot will attempt to navigate through the hazard. It is the captain's responsibility to select waypoints that avoid all hazards.

• Waypoint 4 is too close to 3 to be used in the same route. Waypoints must be far enough apart that the arrival circles do not intersect.

90-8M0099745 eng

MAY 2015 Page 21

Section 2 - On the Water

• A route, including waypoints 1, 2, and 3, is represented by the straight dashed‑line. The autopilot system will attempt to navigate this route. It is the responsibility of the captain to ensure that the route does not contain any hazards, and to keep watch while underway.

45127

Example route

When the track waypoint feature is activated and the boat is put into operation:

• The operator must remain at the helm at all times. The feature is not designed to allow unattended operation of the vessel.

• Do not use track waypoint as the sole source of navigation.

IMPORTANT: Track waypoint can be used only with chartplotters approved by Mercury Marine.

Waypoint data needs to be provided to Mercury autopilot by a third‑party chartplotter. The arrival radius must be no less than

0.05 nautical mile (0.06 mile). Refer to the chartplotter'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.

Waypoint data—distance settings

Between waypoints

Arrival radius alarms

Greater than 1.0 nautical mile (1.15 mile)

No less than 0.05 nautical mile (0.06 mile)

Engaging Track Waypoint Mode

To engage the track waypoint mode:

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

2. Place at least one ERC lever in forward gear. Track waypoint does not function if both levers are in neutral or reverse.

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

IMPORTANT: The vessel must maintain a speed no less than 4.8 km/h (3 mph.) for track waypoint to function.

CAUTION

Avoid injury from unexpected turns at high speeds. Engaging the Track Waypoint or Waypoint Sequence feature while on plane can cause the boat to turn sharply. Confirm the direction of the next waypoint before engaging these autopilot features.

When underway in Waypoint Sequence mode, be prepared to take appropriate action when reaching a waypoint.

4. Press TRACK WAYPOINT on the autopilot trackpad.

• The track waypoint light turns on and a single beep sounds, indicating track waypoint mode is engaged.

NOTE: Two horn beeps sound if track waypoint mode does not engage.

Auto Heading Button in Track Waypoint Mode

While in track waypoint mode, pressing AUTO HEADING changes autopilot to auto heading mode.

Acknowledging a Turn During a Waypoint Arrival

IMPORTANT: Unlike waypoint sequence mode, track waypoint mode will not automatically turn the boat upon arrival at a plotted waypoint.

1. When the boat enters a waypoint arrival zone as indicated by the chartplotter:

90-8M0099745 eng

MAY 2015 Page 23

Section 2 - On the Water

• There will be one long and two short beeps.

• The waypoint sequencing light will start blinking to inform the operator of the arrival.

• VesselView will change its displayed information.

56108

2. If it is safe to change course to the next waypoint, the operator should press WAYPOINT SEQUENCE to acknowledge the waypoint. The autopilot will automatically turn the boat and maneuver to the new course.

3. If it is not safe to change course to the next waypoint, the operator should assume control of the vessel.

IMPORTANT: If the waypoint is not acknowledged or the operator does not assume control of the boat, the autopilot will revert to auto heading and remain on its current course. The autopilot will continue on the course until the operator takes control. If adequate lookout is not maintained, the boat may strike another boat, strike an object in the water, or run aground.

4. If the waypoint is not acknowledged, the autopilot exits track waypoint mode and continues on its current heading in autopilot mode.

5. At the end of the route, input a new waypoint or waypoint route, or take control of the boat. Otherwise, the autopilot reverts to auto heading mode and continues to pilot the boat on its last heading.

56109

Waypoint Sequence

IMPORTANT: Unlike track waypoint mode, waypoint sequence mode will automatically turn the boat upon arrival at a plotted waypoint.

1. Turn on the chartplotter and select a waypoint route to be tracked.

2. Place both ERC levers into forward. Waypoint sequence mode will not engage if either levers are in neutral or reverse.

3. If the track waypoint light is not on, press TRACK WAYPOINT.

4. Press WAYPOINT SEQUENCE to engage the waypoint sequence mode.

Page 24 90-8M0099745 eng

5. VesselView will sound a beep, indicate that the system is in autopilot waypoint sequence, display the compass direction, and indicate that autopilot is locked bearing to waypoint (BTW).

56112

6. If you are in a waypoint arrival zone set by the chartplotter, waypoint sequence mode only informs the autopilot it is okay to proceed to the next waypoint. The waypoint sequence mode acts as a waypoint acknowledge function, and the autopilot sounds a beep when in the zone.

7. If you are not in a previously set waypoint arrival zone, waypoint sequence mode starts auto sequencing to the waypoints in the route. Acknowledge that you understand the information presented in the VesselView pop‑up warning, and press the waypoint sequence button.

56115

8. Stay alert. The boat turns automatically in this mode. You must know if it is safe to turn when the vessel is entering a waypoint arrival zone. Inform passengers that the boat automatically turns so that they can be prepared.

9. To disable the auto sequence mode, press the waypoint sequence button when the boat is not in a waypoint arrival zone.

10. Press the track waypoint button a second time to put the system in standby mode. All lights other than standby turn off.

Cruise Control

The VesselView system features integrated throttle cruise control (cruise), which allows the operator to limit the peak RPM of choice below Wide Open Throttle (WOT). This feature requires VesselView. Refer to the owner's manual provided with your

VesselView for operation instructions.

These additional notes are exclusive to your package:

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

• Cruise resets when the key is turned off.

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

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

Section 2 - On the Water

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.

WARNING

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.

NOTICE

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. All of the ignition keys must be in the ON positions.

2. All of the vessel's ERC levers must be in the neutral position.

3. At the helm you are requesting be made active, press the transfer button once. After the transfer button is pressed, the transfer light turns on and one beep will sound confirming the impending transfer.

51858

Transfer button and light

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 will stop flashing.

4. With the transfer light and neutral light on, press the transfer button a second time to complete the helm transfer.

5. When the helm transfer is complete, another beep sounds and the transfer light turns stays on at the active helm location.

Helm Transfer and Autopilot

Transferring control from an active helm to an inactive helm (from one station to another station) affects the functionality of autopilot modes. Some of the effects are listed.

Page 26 90-8M0099745 eng

MAY 2015

Section 2 - On the Water

• Auto heading mode will disengage when the ERC levers are moved to the neutral position. You must engage auto heading at the selected active helm.

• Requesting a helm transfer places the autopilot into standby mode. Any required inputs will need to be entered at the selected active helm.

• Skyhook will disengage when the transfer button is pressed the second time. Skyhook must be engaged at the selected active helm.

• If auto heading is activated, the helm transfer functionality is disabled. Turn this feature off and resume the transfer. At the selected active helm, engage auto heading.

• If track waypoint is activated, the helm transfer functionality is disabled. Turn this feature off and resume the transfer. At the selected active helm, engage track waypoint.

• Track waypoint control of the route and display of route data on your chartplotter does not automatically transfer to the chartplotter at the active helm. You must turn on the chartplotter at the selected active helm, input the waypoint or waypoint route to be tracked, and engage track waypoint mode.

IMPORTANT: If faults are encountered while attempting to complete a helm transfer, all controlling modules for the engine and the joystick piloting system must be turned off. To turn these controlling modules off, turn both engines off and place both engine ERC handles in reverse full throttle for three seconds.

Battery Information

Long Term Battery Storage & Maintenance Recommendations

When a boat is not going to be used for a long period of time (longer than 3 weeks), steps should be taken to ensure that the batteries are properly maintained to mitigate low voltage issues in the future.

• A battery "maintainer" (smart charger) should be in use anytime the boat is not operational. This is usually done through shore power, but a dedicated battery maintainer can be used directly on a battery if warranted (i.e. boat not equipped with shore power, shore power unavailable, etc). Be sure the battery maintainer is matched to the battery technology in use

(sealed lead acid, absorbed glass mat, etc) and is only used on the appropriate number of batteries.

• Adequate ventilation is always required when batteries are being charged due to the production of O2 and H2 (oxygen and hydrogen), even with sealed batteries. Ensure there is sufficient ventilation where a battery is being charged, regardless of where the batteries are located.

• If the boat is on a trailer, or is being hauled out and placed in dry storage, i.e. on a boat rack or blocks, one should consider physically disconnecting the batteries from the boat and placing them on a maintainer. The batteries could be left in the boat but electrically disconnected from the boat if the batteries are easily accessible for maintanence, the ventilation is sufficient, and temperatures do not drop below freezing (0°C/ 32°F).

• If the boat is being placed onto a boat rack where accessibility is not possible or the battery compartment temperatures are expected to drop well below freezing, i.e., less than ‑10°F, the batteries should be removed from the boat and placed in suitable dry storage area, with maintainers connected and adequate ventilation provided. Even though fully charged batteries can withstand hard freezing temperatures, battery life can be increased by minimizing unnecessary stresses like this.

• In all cases, the battery voltage, specific gravity, and battery level should be monitored periodically during storage.

Recommissioning

• Sometimes a battery may get left off a maintainer. It is paramount to give it a full charge before attempting to embark on a voyage. Most batteries that have sat for a time will take 48‑96 hours to fully charge depending on chemistry, technology, depth of discharge, capacity of maintainer, and general health of the battery.

• When preparing to restore batteries back to operation within the boat, it is paramount to test the batteries to ensure they are fully functional. There are two primary aspects to consider – State of Charge (SOC) and State of Health (SOH). A good test device will determine if a "surface charge" is giving a false indication of a good charge state. State of Health is not as common as SOC, but does indicate remaining useful life of the battery. A SOH test device measures the internal resistance over a frequency range to give you a reading. While it would be prudent to replace a battery if SOH is <50%, do not put a battery into service that has less than a 30% State of Health. A battery load tester is a general indicator of a battery’s ability to provide a cranking current but it is not as accurate as actual SOC and SOH readings.

• Another item of consideration is the quality of the connections being made to the batteries. Inspect for corrosion and poor terminal connections (crimp, corrosion, strand breakage, etc) prior to restoring batteries to full operation. As required, ensure battery cells have adequate electrolyte fluid levels (use only distilled water and no metal funnels!) and use a silicone grease on the battery post terminals.

Transporting a Joystick Piloting Boat

The drives on a joystick piloting‑equipped boat can be moved independently by gravity and the vibrations of traveling, making it possible for the drives to contact each other.

Avoid the possibility of the drives making contact during road transport:

90-8M0099745 eng

MAY 2015 Page 27

Section 2 - On the Water

1. Remove the propellers (optional on short moves).

2. Put the drives in the full‑up, trailer position.

3. Push each drive toward the outside of the boat.

4. Secure the drives with tie‑down straps to prevent the drives from moving.

IMPORTANT: Before launching the boat, remove the tie‑down straps securing the drives.

Section 3 - Troubleshooting

Single Engine Operation

If an engine or steering system stops functioning during use, the remaining drive is electronically limited while turning inboard.

NOTE: Joystick is not available when only one engine is operating.

Drive Limits of Engine with Module Failure

Model

4.5L Axius Joystick Piloting for Sterndrive models

6.2L Axius Joystick Piloting for Sterndrive models

Maximum Inboard Drive Angle Limit

3.0°

IMPORTANT: Intentionally experiencing single engine operation for the first time should be conducted in an open area that is not congested with obstacles or other vessel traffic.

To experience single engine operation, proceed with the following:

1. Ensure the vessel is in an open area with a calm sea.

2. Turn off the engines.

3. Start the starboard engine only.

4. Shift the starboard engine into forward gear.

5. At idle, attempt to steer the vessel, noting how it maneuvers.

6. Advance the throttle slowly while attempting to steer the vessel. Note how it maneuvers.

7. After experiencing single engine operation at various different engine RPMs, shift the starboard engine into neutral.

8. Start the port engine to continue with normal vessel operations.

Port Engine–Only Operation

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

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

Note that joystick is not available in single‑engine operation. However, Axius features redundant trackpad systems, so Auto

Heading mode is still available during single‑engine operation.

Shift Override—Emergency Procedure

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

CAUTION

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

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

To disengage the shift actuator:

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

Page 30 90-8M0099745 eng

MAY 2015

Section 3 - Troubleshooting

WARNING

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

2. Unplug the shift actuator wiring harness connector.

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

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

5. Reset the lanyard.

WARNING

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.

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

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

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

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

Check VesselView First

Your VesselView display is the primary information source for the various functions of your boat. Consult the VesselView display if you suspect something is wrong. VesselView displays faults and other information that can be helpful in determining the current status of various systems that could be causing your concern and the solution to the problem.

Diagnosing DTS Problems

Your authorized Mercury MerCruiser dealer has the proper service tools for diagnosing problems on digital throttle and shift

(DTS) systems. The engine control module (ECM)/propulsion control module (PCM) on these engines has the ability to detect some problems with the system when they occur, and store a Trouble Code in the ECM/PCMs memory. This code can then be read later by a service technician using a special diagnostic tool.

Engine Guardian System

The Engine Guardian System monitors the critical sensors on the engine for any early indications of problems. The system will respond to a problem by emitting a continuous beep and/or reducing engine power in order to provide engine protection.

If Guardian System has been activated, reduce throttle speed. The horn will turn off when throttle speed is within the allowable limit. Consult an authorized Mercury MerCruiser dealer for assistance.

This information is maintained in a database at Mercury Marine to aid authorities and dealers in recovery of stolen power packages.

Attention Required After Submersion

1. Before recovery, contact an authorized Mercury MerCruiser dealer.

2. After recovery, immediate service by an authorized Mercury MerCruiser dealer is required to reduce the possibility of serious engine damage.

Replacement Service Parts

WARNING

Avoid fire or explosion hazard. Electrical, ignition, and fuel system components on Mercury Marine products comply with federal and international standards to minimize risk of fire or explosion. Do not use replacement electrical or fuel system components that do not comply with these standards. When servicing the electrical and fuel systems, properly install and tighten all components.

Marine engines are expected to operate at or near full throttle for most of their life. They are also expected to operate in both fresh and saltwater environments. These conditions require numerous special parts. Exercise care when replacing marine engine parts because specifications are different from those of the standard automotive engine. For example, one of the most important special replacement parts is the cylinder head gasket. Marine engines cannot use steel‑type automotive head gaskets because saltwater is highly corrosive. A marine engine head gasket uses special materials to resist corrosion.

Because marine engines must be capable of running at or near maximum RPM much of the time, they also have special valve springs, valve lifters, pistons, bearings, camshafts, and other heavy‑duty moving parts.

Mercury MerCruiser marine engines have other special modifications to provide long life and dependable performance.

Parts and Accessories Inquiries

Direct any inquiries concerning Quicksilver replacement parts and accessories to your local authorized dealer. The dealer has the necessary information to order parts and accessories for you. Only authorized dealers can purchase genuine Quicksilver parts and accessories from the factory. Mercury Marine does not sell to unauthorized dealers or retail customers. When inquiring about parts and accessories, the dealer requires the engine model and serial numbers to order the correct parts.

Frequently asked questions

The Joystick Piloting system provides intuitive and precise control of your boat, particularly during low-speed maneuvers and docking. It enables you to move the boat in any direction with simple joystick movements.

The system uses independently articulating drives to direct thrust, allowing you to maneuver the boat with greater precision and control. The counterrotating propellers minimize propsteer, ensuring smoother acceleration and deceleration.

Dock Mode reduces the engine RPM throughout the throttle lever range by 50%, giving you finer control of the boat's power in close quarters.

Throttle-Only Mode allows you to increase engine RPM without engaging the gear. This is useful for situations where you want to maintain control of the boat's speed without changing the gear position.

The Autopilot feature allows you to set a specific compass heading or destination (using a chartplotter and GPS unit) and have the boat automatically steer itself to that point. It does not control the boat's speed, only its direction.

WARNING

Traditional Maneuvering with Steering and Thrust

Digital Throttle and Shift (DTS) Features

NOTE: The troll feature is not available on some ERC‑mounted trackpads, only dash‑mounted. For vessels equipped with ERC‑mounted trackpads that do not have a troll button, the troll feature can be accessed from VesselView.

NOTE: On dash‑mounted DTS trackpads, these buttons increase or decrease the trolling speed.

NOTE: When the joystick is enabled while in dock mode, dock mode reduces available power to 70% of the already reduced power with the joystick.

NOTE: Engine RPM and available power will be proportionately reduced throughout the throttle lever range.

NOTE: Dock mode disengages only when the levers are moved into a detent.

NOTE: Throttle‑only mode also affects the joystick. The drives will move and the RPM can be increased, but the gear position will remain in neutral.

NOTE: Pressing

while the ERC levers are in gear will only turn off the throttle‑only light. The engines will remain in throttle‑only mode until the operator returns the levers to the neutral position.

Single Engine Operation

NOTE: Joystick is not available when only one engine is operating.

WARNING

Auto Heading

NOTE: Auto heading does not function with the ERC levers in neutral or reverse.

NOTE: If you must turn the steering wheel for any reason, you will need to apply sufficient force to overcome the electronic detent.

NOTE: VesselView indicates the current heading of the vessel.

NOTE: The joystick must move 100% of its travel for the movement to be recognized as input. A beep will sound.

Track Waypoint

WARNING

CAUTION

NOTE: Two horn beeps sound if track waypoint mode does not engage.

NOTE: The autopilot trackpad turn buttons will not initiate turns while the track waypoint mode is engaged. Turn features are only available in auto heading mode.

Cruise Control

Helm Transfer

WARNING

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.

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.

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 will stop flashing.

NOTE: If the helm transfer is not completed in 10 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.
