(7) Run the engine at idling speed for about3 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 seat storage com- partment and seats in their original posi-
tions.
EJU33736Cleaning the watercraft

(2) 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]
(3) Drain the water from the engine com-
partment. (See page 58 for information
on draining the bilge water.)
(4) Wipe the engine and engine compart- ment with a dry cloth.
(5) Wash down the hull, deck, and jet pump with fresh water.
(6) Wipe the hull, deck, and jet pump with a dry cloth.
(7) Wipe all vinyl and rubber components, such as the seats and engine compart-
ment seals, with a vinyl protectant.
(8) To minimize corrosion, spray metallic parts of the hull, deck, and engine with a
rust inhibitor.

Long-term storageEWJ00332
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. (Seepage 82 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 83 for in-formation on cleaning the watercraft.)
Wax the hull with a non-abrasive wax.
EJU43663Lubrication
To keep moving parts sliding or rotating
smoothly, lubricate them with water-resistant
grease.
