Fuel level

Be sure you have plenty of fuel for your trip. A
good rule is to use 1/3 of your fuel to get to
the destination, 1/3 to return, and to keep 1/3
as an emergency reserve. With the boat level
on a trailer or in the water, check the fuel lev-
el. For fuel filling instructions, see page 35.

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.
