Trimming outboard motor
WARNING
EWM00740
Excessive trim for the operating condi-
tions (either trim up or trim down) can
cause boat instability and can make
steering the boat more difficult. This in-
creases 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 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 brack-
et.
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
angles to find the position that works best for
your boat and operating conditions.
WARNING
EWM00400
● Stop the engine before adjusting the
trim angle.
●
Use care to avoid being pinched when
removing or installing the rod.
●
Use caution when trying a trim position
for the first time. Increase speed gradu-
ally and watch for any signs of instabil-
ity or control problems. Improper trim
angle can cause loss of control.
