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)

Pre-operation check list
Before operating this watercraft, perform the checks in the following check list. See the
accompanying text in this chapter for details on how to perform the checks.
WARNING@ If any item in the pre-operation check list is not working properly, have it inspected
and repaired before operating the watercraft, otherwise an accident could occur.
@
POC-***
NOTE:@ Pre-operation checks should be made thoroughly each time the watercraft is used. This pro-
cedure can be completed in a short time. It is worth the time spent to assure safety and reli-
ability.

Pre-operation check points
EJU10500
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.

EJU19690
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.

Throttle
Squeeze and release the throttle lever
several times to make sure that there is no
hesitation in its travel. It should be smooth
over the complete range, and spring back to
the idle position when released.
WARNING@ Before starting the engine, always check
the operation of the throttle lever.
@
EJU10570
Steering system
Check for looseness in the handlebars.
Turn them as far as possible to the right
and left to make sure that operation is
smooth and unrestricted throughout the
whole range. Make sure that the jet thrust
nozzle also changes directions as the han-
dlebars are turned, and that there is no free
play between the handlebars and the jet
thrust nozzle.

Jet unit
Carefully check the jet intake 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 the jet pump.
In some cases, the engine may overheat
because of lack of cooling water, and dam-
age to the engine could result. Engine cool-
ing water is fed to the engine by the jet
pump. (See page 5-4 for jet intake cleaning
procedures.)
WARNING@ Keep away from intake grate while
engine is on. Items such as long hair,
loose clothing, or PFD straps can
become entangled in moving parts
resulting in severe injury or drowning.
Stop the engine and remove the clip
from the engine shut-off switch before
removing any debris or weeds, which
may have collected around the jet
intake.

Engine shut-off cord (lanyard)
Check that the engine shut-off cord is not
frayed or broken. If the cord is damaged,
replace it; never try to repair it or tie it
together.

Switches
Check the start switch 1, the engine stop
switch 2, and the engine shut-off switch 3
for proper operation.
To check these switches, place the water-
craft in the water to provide adequate cool-
ing. Start the engine, and then pull the
engine shut-off cord 5 to remove the clip 4
from the engine shut-off switch. Verify that
the engine stops immediately. (See pages
2-7 to 2-8 for information on proper opera-
tion of the start switch, the engine stop
switch and the engine shut-off switch.)
EJU10610
Cooling water pilot outlet
Check that water comes out from the out-
lets while the engine is running and the
watercraft is in the water.
EJU10620
Multifunction information center
Check the operation of the multifunction
information center. (See pages 2-15 to 2-19
for multifunction information center.)

2. Attach the clip 1 to the engine shut-off
switch 2. Also, attach the engine shut-
off cord 3 to your left wrist.
WARNING@ Check that the engine shut-off cord is not
frayed or broken, and keep it free from
the handlebars so the engine stops if the
operator falls off. The engine shut-off
cord may not pull free if wrapped around
the handlebars when the operator falls
off, allowing the watercraft to continue to
run and cause an accident.
@
NOTE:@ It is not possible to start the engine with the
clip removed from the engine shut-off
switch.
@
3. Push the start switch (green button).
NOTE:@ The engine will not start if the throttle lever is
squeezed.
@
4. Release the start switch as soon as the
engine starts to run.
CAUTION:@ Never push the start switch while the
engine is running.
Do not operate the start switch for
more than 5 seconds, otherwise the
battery will be discharged and the
engine will not start. Also, the starter
motor may be damaged. If the engine
does not start in 5 seconds, release
the start switch, wait 15 seconds, and
then try again.
