TRIM SWITCH AND KEY PAD FEATURES
1. Trim switch (if equipped) - Operates the trim for all engines.
An accessory trim switch panel is required for trimming
engines individually.
2. Neutral lights - The neutral lights illuminate when the engine
is in neutral gear position. The lights will flash when the engine
is in throttle only mode.
NOTE: Gear position is determined by the position of the shift
actuator on the engine, not the position of the control handle.
3. Troll button - Pressing the "TROLL" button activates troll
control. The troll control feature allows the boat operator to set
the engine speed for slow speed cruising or maneuvering. To
activate, move the control handles into forward detent and
press the button. Use the - or + buttons to decrease or
increase speed, up to the maximum calibrated set point. If troll
control is set at a desired speed and then shut off, the system
remembers the set speed and will return to that speed when
re-engaged. To turn off the troll control press the "TROLL"
button, move the throttle to a different speed, or shift the
engine into neutral.
4. Transfer button - Pressing the "TRANSFER" button allows
engine operation to be transferred to a different helm. Refer
to Helm Transfer.
