Before launching the boat, carefully
check the jet intakes under the boat for
weeds, debris, or anything else that
might restrict the intake of water. If the
intakes are clogged, cavitation could
occur, reducing jet thrust, and possibly
damaging jet pump parts. In some
cases, the engine may overheat
because of a lack of cooling water, and
damage could result. Engine cooling
water is fed to the engine by the jet
pumps (see page 3-10).
Refer to Jet Pump Clean-Out proce-
dures on page 5-5 before attempting to
remove weeds or debris from the jet
intake or impeller areas.
WARNING
Rotating parts could cause severe
injury or death. Before attempting to
remove weeds or debris from the jet
intake or impeller areas; shut off the
engines, remove ignition key, then
remove the engine shut-off switch
cord from the shut-off switch.

INSPECTION," for correct procedure.
Fuel and Engine Oil Levels
1) Turn the right switch key to ON. Wait
for the fuel gauge needle to stop
moving, then note the fuel level. Add
fuel if necessary.
NOTE: The fuel level is most accurate
when the boat is sitting level on the
trailer or in the water.
2) Open the engine hatch, then check
oil level in the engines. Add as nec-
essary (see page 3-3).
Battery
Check the battery condition and the
battery electrolyte level. Make sure
connections are tight and that battery
is properly secured.
WARNING
The battery must always be fully
charged and in good condition.
Loss of battery power may leave you
stranded. Never operate the boat if
the battery does not have sufficient
power to start the engine or if it
shows any other signs of decreased
power.
