Item Control Function
f THROTTLE ONLY
Allows the boat operator to increase engine RPM for warm‑up without shifting the transmission into
gear.
g Decreases brightness settings for the CAN pad, VesselView, and SmartCraft gauges.
h 1 LEVER Enables the throttle and shift functions of both engines to be controlled by the port lever.
i SYNC
Turns off or on the auto‑synchronization feature. Refer to Sync.
NOTE: Not all functions may be active.
Dock
Dock mode is available with joystick operation and remote control lever operation. Dock mode reduces throttle capacity to
approximately 70% of normal joystick throttle demand, allowing finer control of engine power in close quarter situations. If more
power is needed for vessel maneuvering when environmental conditions require more thrust, use the electronic remote control
levers.

Throttle Only
NOTE: On vessels equipped with a joystick, throttle only mode should be used to disable the joystick if the captain is not in
command at the helm. Placing the ERC in throttle only mode will avoid unintended gear engagement. The engines will turn
using the steering wheel or the joystick and the RPM of the engines can be increased while in the throttle only mode, but the
gear position will remain in neutral.

THROTTLE ONLY button
To engage throttle only mode:
1. Place both ERC levers in neutral.
2. Press the THROTTLE ONLY button. The button light will turn on and the neutral lights will blink.
3. Place either ERC lever into gear. The warning horn will beep each time the levers are moved in and out of gear while in
throttle only, but will remain in neutral.
4. The RPM of the engines can be increased.
5. Throttle only mode also affects the joystick. The engines will move and the RPM can be increased, but will remain in
neutral.
NOTE: Pressing the THROTTLE ONLY button while the ERC levers are not in the neutral position turns the button light off and
remains in throttle only mode. You must place the ERC levers into the neutral position to disengage throttle only mode.
To disengage throttle only mode:
1. Place both ERC levers into neutral. Throttle only will not disengage unless the ERC levers are in neutral.
2. Press the THROTTLE ONLY button. The button light will turn off.
