ter flows out continually from the jet
thrust nozzle.
(7) Run the engine at idling speed for about
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.
[ECJ00123]
(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 watertight storage
compartment and seats in their original
positions.
EJU43840Cleaning the watercraft
(1) Remove the seats. (See page 44 for seat
removal and installation procedures.)
(2) If the watercraft will be stored for a week
or more, rustproof the internal enginecomponents to help prevent corrosion.
(See page 85 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.
[ECJ00572]
(4) Drain the water from the engine com-
partment. (See page 55 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.
(8) Wipe all vinyl and rubber components,
such as the seats 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 seats.
(11) Securely install the seats in their original
positions.
EJU33687Battery care
If the watercraft will not be used for more than
a month, remove the battery from the water-
craft, check it, and then store it in a cool, dry
place.
WARNING
EWJ00792
Battery electrolyte is poisonous and dan-
gerous, causing severe burns, etc. Elec-
trolyte contains sulfuric acid. Avoid
contact with skin, eyes, or clothing.

Long-term storage
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.
Storage for long periods of time, such as win-
ter storage, requires preventive maintenance
to ensure against deterioration. It is advisable
to have the watercraft serviced by a Yamaha
dealer prior to storage.
However, the following procedures can be
performed easily by the owner.
EJU40763Cleaning
(1) Flush the cooling water passages. (See
page 81 for information on flushing the
cooling water passages.)
TIP:
If you will be storing the watercraft for a pro-
longed period, such as winter storage, top off
the fuel tank with fresh gasoline and add fuel
stabilizer and conditioner to the fuel tank ac-
cording to the manufacturer’s instruction be-
fore starting the engine.
(2) Clean the watercraft. (See page 82 for in-
formation on cleaning the watercraft.)
Wax the hull with a non-abrasive wax.
EJU43660Lubrication
Use a suitable marine grease applicator and
spray a rust inhibitor between the inner and
outer cables to lubricate the cables and
purge out any dirt and moisture.
To keep moving parts sliding or rotating
smoothly, lubricate them with water-resistant
grease.
Steering cable (jet thrust nozzle end)
Shift rod (reverse gate end)
EJU43860Rustproofing
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 seats. (See page 44 for seat
removal and installation procedures.) Recommended water-resistant grease:

(2) Loosen the clamp screw and disconnect
the air intake duct.
(3) Spray a rust inhibitor into the intake
opening for 3 seconds. WARNING! Do
not spray flammable rust inhibitor
products on engine surfaces while the
engine is hot. The sprayed substance
or propellants could catch fire.
[EWJ00262]
(4) Connect the air intake duct and securely
tighten the clamp screw.
TIP:
Confirm that the air intake duct is inserted
until it touches the protrusion.
After tightening the clamp screw, confirm
that the hose holder is attached in its origi-
nal position.
(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 28 for in-
formation on starting the engine.)
(6) Stop the engine.
(7) Securely install the seats in their original
positions.

(1) Connect the positive (+) jumper cable to
the positive (+) battery terminals of both
batteries.
(2) Connect one end of the negative (–)
jumper cable to the negative (–) battery
terminal of the booster battery.
(3) Connect the other end of the negative (–)
jumper cable to an engine hanger.
(4) Start the engine, and then disconnect the
jumper cables by reversing the steps
above. (See page 28 for information on
starting the engine.)EJU43880Replacing the fuses
If a fuse is blown, replace it with the proper
fuse.
To replace a fuse:
(1) Remove the seats. (See page 44 for seat
removal and installation procedures.)

(2) While pushing both sides of the fuse box
cover inward, pull the cover toward the
port and remove it.
(3) When replacing the SCU fuse, remove
the screws, and then remove the fuse.
Install the spare fuse, and then tighten
the screws.
(4) When replacing a fuse other than the
SCU fuse, remove the fuse using the
fuse puller. Install a spare fuse of theproper amperage. WARNING! Do not
use fuses of a different amperage than
recommended. Substitution with a
fuse that has an improper rating can
cause extensive electrical system
damage and possible fire.
[EWJ00803]
(5) Securely install the fuse box cover in its
original position.
(6) Securely install the seats in their original
positions.
If the fuse immediately blows again, the elec-
trical system may be defective. If this occurs,
have a Yamaha dealer service the watercraft.
EJU34716Towing the watercraft
WARNING
EWJ00812
The operator of the towing boat must
keep speed to a minimum and avoid
traffic or obstacles which could be a
hazard to the operator on the water-
craft.
The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down.
