3 minutes watching the engine condition.
If the engine stops while flushing, turn the
water supply off immediately and perform
the procedure again from step 6.
NOTICE: Do not supply water to the
cooling water passages when the en-
gine is not running. The water could
flow back through the muffler into the
engine, causing severe engine dam-
age.
[ECJ00122]
(8) Turn the water supply off.
(9) Discharge the remaining water out of the
cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(10) Stop the engine.
(11) Remove the garden hose adapter, and
then securely install the flushing hose
connector cap by tightening it until it
stops.
(12) Securely install the seat in its original po-
sition.
EJU41700Cleaning the watercraft
(1) Remove the seat. (See page 37 for seat
removal and installation procedures.)
(2) If the watercraft will be stored for a week
or more, rustproof the internal engine
components to help prevent corrosion.(See page 75 for information on rust-
proofing the internal engine compo-
nents.)
(3) Rinse the engine and engine compart-
ment with a small amount of water.
NOTICE: Do not use high-pressure
water when rinsing the engine or en-
gine compartment as severe engine
damage could result.

(4) Drain the water from the engine compart-
ment. (See page 46 for information on
draining the bilge water.)
(5) Wipe the engine and engine compart-
ment with a dry cloth.
(6) Wash down the hull, deck, and jet pump
with fresh water.
(7) Wipe the hull, deck, and jet pump with a
dry cloth.

such as the seat and engine compart-
ment seals, with a vinyl protectant.
(9) To minimize corrosion, spray metallic
parts of the hull, deck, and engine with a
rust inhibitor.
(10) Allow the engine compartment to air dry
completely before installing the seat.
(11) Securely install the seat in its original po-
sition.

To install the battery:
(1) Place the battery in the battery compart-
ment and hook the battery bands onto the
holders.
(2) Connect the positive (+) battery lead (red)
to the positive (+) battery terminal.
NOTICE: Reversal of the battery leads
will damage the electrical parts.
[ECJ00261]
(3) Connect the negative (–) battery lead
(black) to the negative (–) battery termi-
nal.

EJU41670Rustproofing
Rustproofing the hull, deck, and engine
Spray metallic parts of the hull, deck, and en-
gine with a rust inhibitor.
Rustproofing the internal engine compo-
nents
Rustproof the internal engine components
with a rust inhibitor.
To rustproof the internal engine components:
(1) Remove the seat. (See page 37 for seat
removal and installation procedures.)
(2) Loosen the clamp screw and disconnect
the air intake duct.
(3) Spray a rust inhibitor into the intake open-
ing for 3 seconds. WARNING! Do not
spray flammable rust inhibitor prod-
ucts on engine surfaces while the en-gine is hot. The sprayed substance or
propellants could catch fire.
[EWJ00261]
(4) Connect the air intake duct and securely
tighten the clamp screw.
(5) Make sure that the area around the wa-
tercraft is clear, and then start the engine
in a well-ventilated area and let it run at
idle for 15 seconds. (See page 26 for in-
formation on starting the engine.)
(6) Stop the engine.

(2) Loosen the cap on the electrical box and
remove it.
(3) Replace the blown fuse with the spare
fuse of the correct amperage by using the
fuse puller on the reverse side of the cap.
WARNING! Do not use fuses of a dif-
ferent amperage than recommended.
Substitution with a fuse that has an
improper rating can cause extensiveelectrical system damage and possi-
ble fire.

If the fuse immediately blows again, the elec-
trical system may be defective. If this occurs,
have a Yamaha dealer service the watercraft.
EJU34715Towing the watercraft
WARNING
EWJ00811

The operator of the towing boat must
keep speed to a minimum and avoid traf-
fic or obstacles which could be a hazard
to the operator on the watercraft.

The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down.
If the watercraft becomes inoperative in the
water, it can be towed to shore.
To tow the watercraft:
Use a towline that is three times the combined
length of the towing boat and the watercraft.
(1) Securely attach the towline to the bow
eye of the watercraft being towed.
(2) Sit astride the seat and hold on to the
handlebars in order to balance the water-
craft. NOTICE: The bow must be kept
up out of the water during towing, oth-
erwise water could flood the engine
compartment or water could flow back
into the engine, causing severe en-
gine damage.
[ECJ01330]
Tow the watercraft at 8 km/h (5 mph) or less.
NOTICE: Tow the watercraft at 8 km/h (5
mph) or less, otherwise water could flood
the engine compartment or water could
flow back into the engine, causing severe
engine damage.
[ECJ01321]
EJU36155
Submerged watercraft
If the watercraft is submerged or flooded with
water, drain the bilge water from the engine
compartment. Then, have a Yamaha dealer
service the watercraft as soon as possible.
If the watercraft was submerged:
(1) Remove the watercraft from the water
and drain the water from the storage
compartments. (See page 39 for informa-
tion on draining the storage compart-
ments.)
(2) Drain the bilge water from the engine
compartment. (See page 46 for informa-
tion on draining the bilge water.)
(3) Have the watercraft serviced by a
Yamaha dealer as soon as possible.
NOTICE: Be sure to have a Yamaha
dealer inspect the watercraft. Other-
wise, serious engine damage could re-
sult.
