Throttle only button
‑
Allows engine throttle advancement without shifting the engine. This is done by disengaging the shift
mechanism from the control handle. The throttle only button can be depressed only when the remote control handle is in the
neutral position.
Control handles
‑
Operation of the shift and throttle are controlled by the movement of the control handle. Push the control
handle forward from neutral with a quick firm motion to the first detent for forward gear and continue pushing forward to
increase speed. Pull the control handle back from neutral with a quick firm motion to the first detent for reverse gear and
continue pushing back to increase speed.
Control handle tension adjustment screw (not visible)
‑
This screw is used to adjust the effort required to move the remote

detailed trailer switch operation.
Power Trim
Power trim allows the operator to adjust the sterndrive angle while underway, to provide the ideal boat angle for varying load
and water conditions. Also, the trailering feature allows the operator to raise and lower the sterndrive unit for trailering,
beaching, launching, low speed (below 1200 RPM engine speed), and shallow water operation.
!
WARNING
Excessive trim can cause serious injury or death at high speeds. Use caution when trimming the sterndrive, and never trim
out beyond the gimbal ring support flanges while the boat is underway or at engine speeds above 1200 RPM.
For best performance trim the sterndrive unit so that the boat bottom is at a 3–5° angle to the water.
