Trimming outboard motor
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 an-
gle depends upon the combination of boat,
engine, and propeller. Correct trim is also af-
fected by variables such as the load in the
boat, sea conditions, and running speed.
WARNING
EWM00740
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.
EMU27872
Adjusting trim angle for manual tilt
models
There are 4 or 5 holes provided in the clamp
bracket to adjust the outboard motor trim an-
gle.
1. Stop the engine.
2. Tilt the outboard motor up, and then re-
move the trim rod from the clamp bracket.
3. Reposition the rod in the desired hole.
To raise the bow (“trim-out”), move the rod
away from the transom.
To lower the bow (“trim-in”), move the rod to-
ward the transom.
Make test runs with the trim set to different an-
gles to find the position that works best for
your boat and operating conditions.
