Trimming outboard motor
EWM00741
Excessive trim for the operating condi-
tions (either trim up or trim down) can
cause boat instability and can make steer-
ing 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.
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.

Adjusting trim angle (Power trim and
tilt)
EWM00754
Be sure all people are clear of the out-
board motor when adjusting the trim an-
gle. Body parts can be crushed between
the motor and the clamp bracket when
the motor is trimmed or tilted.
Use caution when trying a trim position
for the first time. Increase speed gradu-
ally and watch for any signs of instability
or control problems. Improper trim an-
gle can cause loss of control.
If equipped with a power trim and tilt
switch located on the bottom cowling,
use the switch only when the boat is at a
complete stop with the engine off. Do
not adjust the trim angle with this switch
while the boat is moving.
Adjust the outboard motor trim angle using
the power trim and tilt switch.
To raise the bow (trim-out), press the switch
“” (up).
To lower the bow (trim-in), press the switch
“” (down).
