Trimming outboard motor
EWM00741
Excessive trim for the operating condi-
tions (either trim up or trim down) can cau-
se boat instability and can make steering
the boat more difficult. This increases the
possibility of an accident. If the boat be-
gins to feel unstable or is hard to steer,
slow down and/or readjust the trim angle.
The trim angle of the outboard motor helps
determine the position of the bow of the boat
in the water. Correct trim angle will help im-
prove performance and fuel economy while
reducing strain on the engine. 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.
