Jet Intakes

Before launching the Jet Boat, careful-

ly 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 lack of cooling water, and

damage could result. Engine cooling

water is fed to the engine by the jet

pumps (see pages 2-11).

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 stop switch lan-

yard from the stop switch.

Fuel System

Refer to page 4-11, "FUEL SYSTEM

INSPECTION," for correct procedure.

Fuel and Engine Oil Levels

1) Turn the main 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, remove the

center storage tray, then check oil

level in the tank. Add as necessary.

Battery

The Jet Boat uses one battery. Check

the battery condition and the battery

electrolyte level. Make sure connec-

tions are tight and that battery is prop-

erly secured.

The battery must always be fully

charged and in good condition. Loss

of battery power may leave you

stranded. Never operate the Jet Boat

if the battery does not have suffi-

cient 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
