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. Open the hood and remove the front
storage compartment, to check the fuel
level. (See page 2-20 for front storage
compartment.)
2. Open the fuel tank filler cap, and slowly
add fuel to the fuel tank.
3. Stop filling when the fuel just reaches the
bottom of the filler tube on the fuel tank.
Do not fill into the filler tube, because
fuel could spill out.
Fuel tank capacity:
Total: 60 L (15.9 US gal, 13.2 Imp gal)

cedure can be completed in a short time. It is worth the time spent to assure safety and reli-
ability.

Engine compartment
Ventilate the engine compar tment before
each use.
To ventilate the engine compartment,
remove seat and front storage compart-
ment. (See page 2-5 for seat, and 2-20 for
front storage compartment.) Allow the
engine compartment to remain open for a
few minutes to allow any fuel vapors to
escape. Also, check for loose electrical con-
nections.
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 a loose electrical connection.

EJU20071
Fuel and oil systems
Check the fuel system for leakage, cracks
or malfunctions before each use. (See page
4-10 for check points and correct proce-
dures.)
1. Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.
2. Remove seat and front storage compart-
ment. (See page 2-5 for seat, and 2-20
for front storage compartment.)
3. Check the fuel and oil levels in the tanks
and replenish if necessary. (See pages
3-4 and 3-5 for filling instructions.)

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.
Place a drain pan under the water separator
to catch the draining water or use a dry cloth
to soak up any water that could spill into the
watercraft. If any water spills into the water-
craft, be sure to wipe it up with a dry cloth.
Be sure to install the drain screw after drain-
ing the water separator.
EJU20200
Bilge
Check for moisture and fuel residue in the
bilge.
This watercraft is equipped with a conven-
tional jet vacuum bilge draining system and
an electric bilge draining system. The elec-
tric bilge draining system is operated when
the engine is running. When excess water
reaches the water inlet of the electric bilge
pump, the water is discharged via the
exhaust passage from the jet thrust nozzle.
A small quantity of water will remain in the
bilge and should be removed manually. To
remove any residual water, perform the fol-
lowing procedure.
To remove water from the bilge:
1. Remove the stern drain plugs.
2. Raise the bow of the watercraft until the
water drains.
3. After the water has drained, wipe the
bilge with dry rags to make sure that the
bilge is thoroughly dry.
4. Install the drain plugs.

CAUTION:@
Make sure that the stern drain plugs
are tightened securely before launch-
ing the watercraft.

Clean any foreign materials, such as
dirt or sand, from the drain plug
threads before installing the drain
plugs.

Battery
Check the battery condition and the elec-
trolyte level.
Check that the battery leads are tightened
securely and there is no corrosion on the
battery terminals.
WARNING@
The battery must always be fully
charged and in good condition. Loss
of battery power may leave you
stranded. Never operate the watercraft
if the battery does not have sufficient
power to start the engine or if it shows
any other signs of decreased power.

Be sure to connect the breather hose
to the battery. Fire or explosion could
result if the breather hose is damaged,
obstructed, or not connected properly.
@
Make sure that the battery is securely
held in place.
