Before launching the boat, carefully
11 12 13 14 15 16 17 18 19 20
check the jet intakes under the boat

for weeds, debris, or anything else

31 32 33 34 35 36 37 38 39 40 that might restrict the intake of water.

could occur, reducing jet thrust, and
41 42 43 44 45 46 47 48 49 50 possibly damaging jet pump parts. In
51 52 53 54 55 56 57 58 59 60
some cases, the engine may overheat
51 52 53 54 55 56 57 58 59 60
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.

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.
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.

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-
