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.
EJU42771Flushing 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 removable water-
tight storage compartment. (See page 49
for seat removal and installation proce-
dures and page 55 for information on the
removable watertight storage compart-
ment.)
(3) Open the stern storage compartment.
(See page 54 for information on the stern
storage compartment.)(4) Connect the garden hose adapter to a
garden hose.
(5) Loosen the flushing hose connector cap
and remove it. Insert the garden hose
adapter into the flushing hose connector
by pushing and twisting it until it is se-
curely connected.
(6) Connect the garden hose to a water tap.
(7) 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-

ter flows out continually from the jet
thrust nozzle.
(8) 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 7.
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]
(9) Turn the water supply off.
(10) Discharge the remaining water out of the
cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(11) Stop the engine.
(12) Remove the garden hose adapter, and
then securely install the flushing hose
connector cap by tightening it until it
stops.
(13) Securely close the stern storage com-
partment.
(14) Securely install the removable watertight
storage compartment and seats in their
original positions.
EJU33736Cleaning the watercraft
(1) Remove the seats. (See page 49 for seat
removal and installation procedures.)(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 60 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.
(9) Allow the engine compartment to air dry
completely before installing the seats.
(10) Securely install the seats in their original
positions.
EJU33688Battery 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.
Antidotes
External: Flush with water.
Internal: Drink large quantities of water or
milk. Follow with milk of magnesia, beaten

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 86 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 87 for in-
formation on cleaning the watercraft.)
Wax the hull with a non-abrasive wax.
EJU44741Lubrication
To keep moving parts sliding or rotating
smoothly, lubricate them with water-resistant
grease.
Steering cable (jet thrust nozzle end), elec-
tric trim rod (jet thrust nozzle end), and ball
joint
TIP:
Disconnect the electric trim rod from the ball
joint before lubricating.
Shift rod (reverse gate end) and ball joint
TIP:
Disconnect the shift rod from the ball joint be-
fore lubricating.
EJU40812Rustproofing
Spray metallic parts of the hull, deck, and en-
gine with a rust inhibitor.
Have a Yamaha dealer rustproof the internal
engine components.
