Jet Intakes
Jet Thrust Intakes
Intake Grates
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.
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.

Fuel System
Refer to page 4-10, “FUEL SYSTEM
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 con-
nections are tight and that battery is
properly secured.
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.
Drainage System
Self-Bailing Deck—
Most water which enters the deck area
bails automatically out the stern through
the large drain hole in the deck. A one-
way check valve in the drain prevents
