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 removable watertight
storage compartment and seats in their
original positions.
EJU43840Cleaning the watercraft
(1) Remove the seats. (See page 43 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 84 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 54 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.

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 80 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 81 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)
EJU44140Rustproofing
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 43 for seat
removal and installation procedures.)
(2) Release the hooks on the port side of the
air filter case, and then lift up the air filter
case cover. NOTICE: Do not lift up the
air filter case cover forcefully. Other- Recommended water-resistant grease:

wise, the fuel hose that is secured to
the air filter case cover could be dam-
aged.
[ECJ02620]
(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) Place the air filter case cover in its origi-
nal position, and then fit the hooks onto
the cover.
TIP:
Make sure that the air filter case cover is se-
curely installed.
(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 atidle for 15 seconds. (See page 27 for in-
formation on starting the engine.)
(6) Stop the engine.
(7) Securely install the seats in their original
positions.
