EJU40242After removing the watercraft from
the water
NOTICE
ECJ01311
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 overheat.
After operating and removing the watercraft
from the water, promptly discharge the re-
maining water from the cooling water pas-
sages.
To discharge water from the cooling water
passages:
(1) Make sure that the area around the wa-
tercraft is clear, and then start the en-
gine.
(2) Discharge the remaining water out of the
cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(3) Stop the engine.

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.
EJU43652Flushing the cooling water passages
NOTICE
ECJ01311
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 overheat.
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 43
for seat removal and installation proce-
dures and page 48 for information on the
removable watertight storage compart-
ment.)(3) Connect the garden hose adapter to a
garden hose.
(4) 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.
(5) Connect the garden hose to a water tap.
(6) 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.
(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 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.
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.

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.
EJU43663Lubrication
To keep moving parts sliding or rotating
smoothly, lubricate them with water-resistant
grease.
Steering cable (jet thrust nozzle end)
VX / VX Deluxe / VX Cruiser / VX Limited:
Shift rod (reverse gate end) and ball joint
TIP:
Disconnect the shift rod from the ball joint be-
fore lubricating.
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:
