Controls

Tiller handle models:
Move the tiller handle fully to the left and
right to make sure operation is smooth.
Turn the throttle grip from the fully closed
to the fully open position. Make sure that it
turns smoothly and that it completely re-
turns to the fully closed position.
Look for loose or damaged connections of
the throttle and shift cables.
Remote control models:
Turn the steering wheel full-right and full-
left. Make sure operation is smooth and un-
restricted throughout the whole range with
no binding or excessive free play.
Operate the throttle levers several times to
make sure there is no hesitation in their
travel. Operation should be smooth over
the complete range of motion, and each le-
ver should return completely to the idle po-
sition.
Look for loose or damaged connections of
the throttle and shift cables.
