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 impact
the steering wheel or other parts of the
boat. This could increase the risk of se-
rious 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 di-
rection.

EMU27821

Stopping engine

Before stopping the engine, first let it cool off
for a few minutes at idle or low speed. Stop-
ping the engine immediately after operating at
high speed is not recommended.

EMU27833

Procedure

1.

Push and hold the engine stop button un-
til the engine comes to a complete stop.

2.

After stopping the engine, tighten the air
vent screw on the fuel tank cap and set
the fuel cock lever or knob to the closed
position, if equipped.

3.

Disconnect the fuel line if you are using
an external fuel tank.

TIP:

If the outboard motor is equipped with an en-
gine shut-off cord, the engine can also be
stopped by pulling the cord and removing the
clip from the engine shut-off switch.

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 steer-
ing the boat more difficult. This increases
