■EKS fob

Place and hold the EKS fob over the lock indicator in EKS All panel or EKS panel to lock and unlock the EKS.

TIP:

• Be sure to lock the EKS when leaving the boat, or when leaving the operator's seat if children are nearby. Also, check that the lock indicator is blinking.
• Rapid repeat operation of the EKS fob lock/unlock function may result in improper operation of the EKS. When locking or unlocking the EKS, remove the EKS fob from over the lock indicator and wait at least 1-second before initiating another lock/unlock command.
• When locking/unlocking with the EKS fob, do not place the key close to devices possessing a magnetic field, as this may prevent the lock/unlock operation.
• The EKS will register up to four EKS fobs. Have a Yamaha dealer register any additional EKS fobs.
• When operating or stopping the boat, be sure to carry the EKS fob with you and take care not to lose it.
• If any EKS fob is lost, be sure to have a Yamaha dealer delete the registration of the lost key number for security reasons.
• While operating the ignition switch or engine start switch, do not turn the steering wheel or perform any system operations at the same time, otherwise unexpected errors may occur.

- Interference from other electronic devices (radios) could affect locking and unlocking of the system. Confirm the system has locked before leaving the boat. Repeat the locking/unlocking procedure if necessary.

Lock

When the EKS fob is placed over the lock indicator, the beeper sounds once. This indicates the lock mode is selected and the ignition switch cannot be turned to "ON". When in lock mode, the EKS panel lock indicators blink. When the ignition switch is OFF, or the ignition switch is ON and the engines are not running, locking can be performed.

Unlock

When the EKS fob is placed over the lock indicator, the beeper sounds twice. This indicates the unlock mode is selected and the ignition switch can be turned to "ON".

EKS	Number of beeps	Engine can be started	Lock indicator
Lock 1 beep No Blink
Unlock 2 beeps Yes Off

Ignition switch

Pushing the ignition switch turns the power to each engine ON and OFF. When the power is ON, the active indicator will be illuminated.

■Start/stop switch

Pushing the start/stop switch starts and stops each engine. The active indicator will be illuminated when the engine is running.

■All ignition switch

Pushing the All ignition switch turns power to all engines ON and OFF. The active indicators will be illuminated when the power is ON.

■All start/stop switch

Pushing the All start/stop switch starts and stops all engines. The active indicators will be illuminated when the engines are running.

Engine shut-off switch

The clip must be attached to the engine shut-off switch for the engines to run. The cord should be attached to a secure place on the operator's clothing, or arm or leg. Should the operator fall overboard or leave the helm, the cord will pull out the clip, turning all engines OFF. This will prevent the boat from running away under power.

WARNING

Attach the engine shut-off cord to a secure place on your clothing, or your arm or leg while operating. Do not attach the cord to clothing that could tear loose. Do not route the cord where it could become entangled, preventing it from functioning. Avoid accidentally pulling the cord during normal operation. Loss of engine power means the loss of most steering control. Also, without engine power, the boat could slow rapidly. This could cause people and objects in the boat to be thrown forward.

Function and operation of components

■Remote control lever

Moving the remote control levers from the neutral (N) position to the forward (F) position (towards the bow of the boat) makes the boat move forwards, while moving it to the reverse (R) position (towards the stern of the boat) makes the boat move backwards. The boat will be moving with the engine at idle. Moving the lever farther opens the throttle, and the engine will begin to accelerate.

1. Shift
2. Fully closed
3. Throttle
4. Fully open

The twin lever provides control of gear shifting and throttle operation for all engines. The PORT and CENTER PORT engines are controlled by the PORT control lever. The STBD and CENTER STBD engines are controlled by the STBD control lever.

The CENTER PORT engine's operation is synchronized with the PORT engine operation.

The CENTER STBD engine's operation is synchronized with the STBD engine operation.

■Lever friction adjuster

The remote control can be adjusted to suit operator preference. Friction brakes adjust the effort to move the remote control levers. Shift position detents adjust the click felt when engaging the shift positions. Turn the adjusters clockwise to increase the friction or detent pressure. Turn counterclockwise to reduce the friction or detent pressure.

WARNING

• If the friction brakes or shift position detents are too loose, the remote control levers may move too quickly, causing accidents.
• Do not over-tighten the friction brakes and shift position detents. If the remote control levers movement is too heavy, it may hinder the handling of the boat, causing accidents.

When only center engine(s) is running by the START/STOP ignition switch(es), the CENTER PORT engine can be controlled by the PORT remote control lever and the CENTER STBD engine can be controlled by the STBD remote control lever without using the center engine switch.

■Speed control switch

The speed control switch "1" in conjunction with the engine RPM (center trim) switch "3" allow the operator to easily make small engine speed adjustments.

The remote control lever(s) must be in forward (F) position before activating speed control. The active indicator will be illuminated during operation. Each time the UP side of the engine RPM switch is pressed the engine speed will gradually increase and pressing the DN side of the switch will gradually decrease speed.

1. Active indicator
2. Trim assist switch

Trim assist mode does not operate in the free throttle mode and joystick mode. Pushing the trim assist switch exits from trim assist mode. The active indicator will go out.

When the trim assist function has been switched ON, it will remain active until cancelled by the operator even when turning the ignition switch OFF and back to ON.

■Power Trim and Tilt (PTT) switch

The PTT system adjusts the position of the engines in relation to the transom. PTT switch "1" controls all engines simultaneously. PTT switches "2", "3" and "4" control each engine individually. When the engines are in the fully down position, pressing UP will first move the engine(s) through the trim range then into tilt range. Pressing DN will lower the engine(s). When the switches are released, the engine(s) will stop in it's current position.

WARNING

• Be sure all people are clear of the outboard motor when adjusting the trim angle. Body parts can be crushed between the motor and the clamp bracket when the motor is trimmed or tilted.
• Use caution when trying a trim position for the first time. Increase speed gradually and watch for any signs of instability or control problems. Improper trim angle can cause loss of control.

NOTICE

The engines should not be operated when in the tilt range. If absolutely necessary due to shallow water conditions: make sure the cooling water inlets are submerged, do not run above idle speed and do not accelerate until the engines are lowered into the trim range.

TIP:

When speed control is active, the center PTT switch "3" acts as the engine RPM switch. Switches "2" and "4" will be inactive. Raise and lower all engines using PTT switch "1".

WARNING

• Set-Point automatically operates the engines as needed when the system is engaged to help keep the boat in the set location. Do not use the system when people are in the water or other vessels or obstacles are nearby because of the possibility they could be struck by the propellers or boat when the boat is correcting position. The operator also must be prepared to assume full control at the helm if Set-Point control disengages unexpectedly.
• 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 Set-Point is engaged, the propellers rotate and the boat moves to maintain the position of the boat. Stop the engines and disengage Set-Point immediately if anyone enters the water near the boat.

Transportation with boat (trailering)

WARNING

• Do not use the service/mooring tilt support levers to support the motors when trailering the boat.
• Ensure steering lock clips are removed BEFORE operating boat. Failure to remove steering lock clips may result in no steering control.

NOTICE

• To prevent unintentional steering movement, secure all motors in the straight ahead position using the steering lock clips.
- To prevent interference between the outboard motors, position all motors straight ahead while using the PTT to tilt only one motor, in and out.
- When trailering the outboard motors in the tilt position, make sure there is sufficient clearance between the outboard motors, including the steering cylinders, and any surfaces of the boat to prevent interference due to shock or vibration during transportation.

The outboard motors should be trailered in the straight ahead direction and normal running position secured with the steering lock clips. If there is insufficient road clearance in this position, tilt and support the outboard motors using Yamaha Trailer Supports or similar devices such as transom savers.

TIP:

If the steering lock clips are damaged or lost, place an order for replacement.
