Stopping boat
WARNING
EWM02321
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 load or other parts of the boat. This
could increase the risk of serious injury. It
could also damage the shift mechanism.
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...

Tilting up and down
If the engine will be stopped for some time or
if the boat is moored in shallows, the outboard
motor should be tilted up to protect the propel-
ler and lower case from damage due to colli-
sions with obstructions, and also to reduce
salt corrosion.
WARNING
EWM00222
Make sure that no one is near the outboard
motor when tilting the outboard motor up
or down. Otherwise, body parts could be
crushed between the outboard motor and
the clamp bracket.
