TIP:
It will take about 60 seconds for the water
to reach the outlets after the engine is start-
ed.
Water discharge may not be constant
when the engine is running at idling speed.
If this occurs, apply a little throttle to make
sure that water discharges properly.
EJU40323Water separator
The water separator prevents water from en-
tering the fuel tank by collecting any water
that has entered the fuel tank breather hose if
the watercraft was capsized.
If water has collected in the water separator,
drain it by loosening the drain screw.
To drain water from the water separator:
(1) Place a drain pan or dry cloth under thewater separator. (2) Gradually loosen the drain screw to drain
the water. Catch the draining water in the
drain pan or soak it up with the dry cloth
so that it does not spill into the engine
compartment. If any water spills into the
watercraft, be sure to wipe it up with a
dry cloth.
(3) Securely tighten the drain screw until it stops.

(4) Push the hood latch, and then lift up therear of the hood.
(5) Loosen the fuel filler cap and remove it.
(6) Slowly add fuel to the fuel tank.
(7) Stop filling when the fuel level reaches approximately 50 mm (2 in) from the top of the fuel tank. Do not overfill the fuel
tank. Because fuel expands when it
heats up, heat from the engine or the sun
can cause fuel to spill out of the fuel tank.
Do not leave the watercraft with a full
tank in direct sunlight.
(8) Wipe up any spilled fuel immediately with a dry cloth.
(9) Securely install the fuel filler cap by tight- ening it until it clicks.
(10) Push the rear of the hood down to se- curely lock it in place. Make sure that the
fuel filler cap and the hood are securely
closed before using the watercraft.
(11) Securely install the seats in their original positions.

Pre-operation checks
56
EJU32282
Pre-operation check pointsEJU41312Pre-launch checks
Perform the pre-launch checks in the pre-op-
eration checklist while the watercraft is on
land.
To perform the pre-launch checks:
(1) Remove the seats and watertight stor-age compartment. (See page 40 for seat
removal and installation procedures and
page 45 for information on the watertight
storage compartment.)
(2) Perform the checks and make sure that there are no malfunctioning items or oth-
er problems.
(3) After completing these checks, securely install the watertight storage compart-
ment and seats in their original positions.
EJU32334Engine compartment check
WARNING
EWJ00462
Failure to ventilate the engine compart-
ment could result in a fire or explosion. Do
not start the engine if there is a fuel leak.
Ventilate the engine compartment. Leave the
engine compartment open for a few minutes
to allow any fuel vapors to escape.
Make sure that there is no damage inside the
engine compartment.
EJU34215Fuel system checks
WARNING
EWJ00382
Leaking fuel can result in fire or explosion.
Check for fuel leakage regularly.
If any fuel leakage is found, the fuel sys-
tem must be repaired by a qualified me-
chanic. Improper repairs can make the
watercraft unsafe to operate.
Make sure that there is no damage, leakage,
or other problem in the fuel system.
Check:
Fuel filler cap and seal for damage
Fuel tank for damage and leakage
Fuel hoses and joints for damage and leak-
age
Fuel tank breather hose for damage and
leakage
EJU36875Fuel level check
Check the fuel level in the fuel tank.
Add fuel if necessary. (See page 47 for infor-
mation on filling the fuel tank.)
EJU32424Water separator check
Make sure that no water has collected in the
water separator. If water has collected in the
water separator, drain it. (See page 30 for in-
formation on draining the water separator.)

EJU37146
Post-operation care
WARNING
EWJ00331
Always place the watercraft upright in a
horizontal position when storing it, other-
wise fuel could leak out into the engine or
engine compartment, which could create
a fire hazard.
After using the watercraft, always take it out
of the water, clean it, and store it. Leaving the
watercraft in the water for extended periods
will accelerate the rate of normal deteriora-
tion of the jet pump and hull. Marine organ-
isms and corrosion are some of the
conditions that can shorten the life of many
watercraft components.
EJU37564Flushing the cooling water passages
NOTICE
ECJ01880
Do not run the engine over 4000 r/min on
land. Also, do not run the engine for
more than 15 seconds without supplying
water, otherwise the engine could over-
heat.
Flush the cooling water passages to
prevent them from clogging with salt,
sand, or dirt.
(1) Place the watercraft in a horizontal posi-tion.
(2) Remove the seats and watertight stor- age compartment. (See page 40 for seat
removal and installation procedures and
page 45 for information on the watertight
storage compartment.) (3) Connect the garden hose adapter to a
garden hose.
(4) Loosen the flushing hose connector cap and remove it. Insert the garden hose
adapter into the flushing hose connector
and turn it until it is securely connected.
(5) Connect the garden hose to a water tap.
(6) Make sure that the area around the wa- tercraft is clear, and then start the en-
gine. Immediately after the engine starts,
fully turn the water supply on so that wa-
