Trimming

Maneuvering/Control Hazard

Ensure continuous visibility of other boats, swimmers,
and obstacles during bow-up transition to planning.

Adjust engine to an intermediate trim as soon as boat is
on plane to avoid possible ejection due to boat spinout.
Do not attempt to turn boat when engine is trimmed
extremely down/under/in.

Most stern drive and outboard engines have a power
trim, which enables you to change the angle of your
drive unit by pressing a button. See your engine
operator's manual for a complete discussion of
characteristics resulting from different trim settings.

Power trim is designed to give quick acceleration with
minimum time in the bow-up transition to planing. This
is most easily accomplished by trimming the engine
fully down/under/in and setting the throttle at moderate
to maximum.

Once on plane, trim the engine up/out slightly to avoid a
bow-down condition called "plowing". Plowing can
cause inefficient and unpredictable "bow steering" or
"oversteering". In this condition, attempting to turn or
encountering a moderate wave may result in an abrupt
turn or spinout.

Trimming the engine too far up/out can cause a bow-up
condition leading to "porpoising" (bouncing) or
propeller ventilation. If you notice a sudden increase in
propeller speed, reduce engine RPM and trim the drive
unit down/under/in until propeller ventilation stops.
