Gasoline
WARNING@ GASOLINE AND ITS VAPORS ARE
HIGHLY FLAMMABLE AND EXPLOSIVE!

Do not smoke when refueling, and
keep away from sparks, flames, or
other sources of ignition.

Stop engine before refueling.

Refuel in a well-ventilated area. Do not
stand or sit on the watercraft while
refueling in case of fire.

Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.

Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level just reaches the
bottom of the filler tube. Do not fill up
the filler tube because fuel expands as
it warms up and could overflow.

Tighten the filler cap securely after
refueling.

If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.

If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.
@
CAUTION:@ Use only fresh gasoline that has been
stored in clean containers.
@
Recommended gasoline:
Regular unleaded gasoline with a
minimum octane rating of
86 (Pump octane number) = (R+M)/2
90 (Research octane number)

Filling the fuel tank
CAUTION:@ Be careful when refueling. Avoid getting
water or other contaminants in the fuel
tank. Contaminated fuel can cause poor
running or engine damage.
@
1. Lift the steering pole and support it with
the lock pin.
2. Remove the hood.
3. Open the fuel tank filler cap, and slowly
add the premixed fuel to the fuel tank.
4. Stop filling when the fuel level just
reaches the bottom of the filler tube.
NOTE:@
The hood must be removed in order to
watch the fuel level in the fuel tank while
adding fuel.

Be careful not to spill fuel or overfill the
tank.

Do not fill into the filler tube because fuel
could overflow.
@
Fuel tank capacity:
Total: 18 L (4.8 US gal, 4.0 Imp gal)
Reserve: 5.5 L
(1.45 US gal, 1.21 Imp gal)

Engine compartment
Ventilate the engine compartment, before
each use. To ventilate the engine compart-
ment, lift the steering pole and support it
with the stopper pin, then remove the hood.
Put the hood aside for a few minutes to allow
any fuel vapors to escape. Also, check for
loose electrical connections.
WARNING@ Failure to ventilate the engine compart-
ment could result in fire or explosion. Do
not start the engine if there is a fuel leak
or loose electrical connection.
@
EJU01279
Fuel system
Check the fuel system for leakage, cracks
or malfunctions before each use. (See
page 4-10 for check points and correct pro-
cedures.)
1. Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.
2. Remove the hood, and then check the
fuel level in the tank. Replenish if neces-
sary. (See page 3-4 for filling instruc-
tions.)
3. Close the fuel tank filler cap securely.

Water separator
Check the water separator 1 for water.
Normally the water separator is empty. The
water separator retains any water entering
through the fuel tank breather hose if the
watercraft is capsized.
If water remains in the water separator,
drain it by removing the drain screw 2.
Install the drain screw again after draining
the water separator.
EJU01280
Bilge
Check for moisture and fuel residue in the
bilge.
Excessive water in the bilge can splash
into the carburetor and engine which could
cause engine damage.

Starting the engine
WARNING@ Never start the engine or let it run for any
length of time in an enclosed area.
Exhaust fumes contain carbon monox-
ide, a colorless, odorless gas that may
cause loss of consciousness and death
within a short time. Always operate the
watercraft in an open area.
@
1. Launch the watercraft in water free from
weeds and debris and at least 60 cm
(2 ft) deep.
WARNING@ Never operate in water that is less than
60 cm (2 ft) deep, otherwise you increase
your chance of hitting a submerged
object, which could result in injury.
@
CAUTION:@ Never operate in water that is less than
60 cm (2 ft) deep, otherwise pebbles or
sand could be sucked into the jet intake,
causing impeller damage or engine over-
heating.
@
2. Turn the fuel cock knob to the “ON” posi-
tion.
NOTE:@ Before starting the watercraft, after it has
been sitting, remove the fuel tank filler cap
to release any built-up pressure in the tank
due to fuel expansion.
