Direct drive models
Before beginning operation, allow the engine
to warm up at idle speed for 3 minutes. Failure
to do this will shorten engine life. WARNING!
The propeller rotates whenever the engine
is running. Do not move the throttle con-
trol lever from the start position during
warm-up. The boat could unexpectedly
start to move, which could result in an ac-
cident.

The boat is not equipped with a separate
braking system. Water resistance stops it af-
ter the throttle lever is moved back to the fully
closed position. The stopping distance varies
depending on gross weight, water surface
conditions, and wind direction.
