Stopping boat
WARNING
EWM01510
●
Do not use the reverse function to slow
down or stop the boat as it could cause
you to lose control, be ejected, or im-
pact the steering wheel or other parts of
the boat. This could increase the risk of
serious injury. It could also damage the
shift mechanism.
●
Do not shift into reverse while traveling
at planing speeds. Loss of control, boat
swamping, or damage to the boat could
occur.
The boat is not equipped with a separate
braking system. Water resistance stops it af-
ter the throttle lever is moved back to idle.
The stopping distance varies depending on
gross weight, water surface conditions, and
wind direction.

EMU27862
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.
