lever forward. Achieve wide‑open throttle (WOT) by placing the throttle lever in its full forward position. Decrease RPM by
moving the throttle lever back. Achieve minimum RPM (idle) by placing the throttle lever in its full aft position.

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.

Trimming sterndrive unit up/out can:
•

•
Increase clearance over submerged objects or a shallow bottom
•
Cause boat to accelerate and plane off slower
•
In excess, cause boat porpoising (bouncing) or propeller ventilation
•
Cause engine overheating if trimmed up/out to a point where any cooling water intake holes are above the waterline

Trimming sterndrive unit down/in can:
•
Help the boat accelerate and plane off quicker
•
