TRIMMING OUTBOARD
MOTOR
The trim angle of the outboard motor
helps determine the position of the bow
of the boat in the water. The correct trim
angle will help improve performance and
fuel economy while reducing strain on the
engine. The correct trim angle depends
upon the combination of boat, engine,
and propeller. Correct trim is also affected
by variables such as the load in the boat,
sea conditions, and running speed.

steering the boat more difficult. This
increases the possibility of an accident. If
the boat begins to feel unstable or is hard
to steer, slow down and/or readjust the
trim angle.

ANGLE" for instructions on usage.
