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
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.
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.

WARNING

●
Be sure all people are clear of the out-
board motor when adjusting the tilt an-
gle, also be careful not to pinch any
body parts between the drive unit and
clamp bracket.
●
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.
●
Use the power tilt switch located on the
bottom engine cowling (if equipped)
only when the boat is at a complete
stop with the engine off.
