Trimming outboard motor
WARNING
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
WARNING
EWM02472
Make sure that all people are clear of the
outboard motor when adjusting the trim
angle. Body parts can be crushed be-
tween the outboard motor and the
clamp bracket when the outboard motor
is trimmed or tilted.
Use caution when trying a trim angle for
the first time. Increase speed gradually
and watch for any signs of instability or
control problems. Improper trim angle
can cause loss of control.
If the outboard motor is 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 an-
gle 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), push the “
” (up)
side of the switch.
To lower the bow (trim-in), push the “
”
(down) side of the switch.
