Operation - Yamaha EXCITER SE Owner's Manual

Jet Intake
Before launching the Jet Boat, careful-
ly check the jet intake under the boat
for weeds, debris, or anything else that
might restrict the intake of water. If the
intake is 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
pump (see pages 2-11).
Refer to Jet Pump Clean-Out proce-
dures on page 5-4 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
engine, remove ignition key, then
remove the engine stop switch lan-
yard from the stop switch.
O
Fuel System
Refer to page 4-10, "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, then check
oil level in the tank. Add as neces-
sary.
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.
WARNING
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
sufficient power to start the engine
or if it shows any other signs of
decreased power.
