Trim / Propeller Selection

A. Trim
Boat trim while underway greatly affects boat performance and efficiency. For best results, the boat should be
on plane and trimmed to reduce the wetted surface. With less boat in the water, both speed and fuel mileage
increases.
•
Trim the engine in. As you speed up, your boat will increase its angle of trim, causing the bow to rise. You
can limit this effect by adjusting the angle of the engine. The propeller needs to be trimmed in to force the
bow down and force the stern up at the start of a run.
Always keep one hand on the steering wheel and
other on the throttle. If the boat begins to operate in
an unsafe way pull back on the throttle and trim the

•
Once on plane, the engine should be trimmed out a little to avoid a bow down condition called "plowing."
Plowing can cause "bow-steering" or "oversteering" and inefficiently consume horsepower. In this
condition, if attempting a turn or encountering diagonal moderate wake, a more abrupt turn than intended
may result.
