To fill the fuel tank:
(1) Before refueling, stop the engine. Do notstand or sit on the watercraft. Never refu-
el while smoking, or while in the vicinity
of sparks, open flames, or other sources
of ignition.
(2) Place the watercraft in a well-ventilated area and in a horizontal position.
(3) Remove the seats, and then check the fuel level. (See page 54 for seat removal
and installation procedures.)
(4) Loosen the fuel filler cap and remove it.
(5) Slowly add fuel to the fuel tank.
(6) Stop filling when the fuel level reaches approximately 50 mm (2 in) from the top
of the fuel tank. Do not overfill the fuel
tank. Because fuel expands when it heats up, heat from the engine or the sun
can cause fuel to spill out of the fuel tank.
Do not leave the watercraft with a full
tank in direct sunlight.
(7) Wipe up any spilled fuel immediately with a dry cloth.
(8) Securely install the fuel filler cap by tight- ening it until it clicks.
(9) Securely install the seats in their original positions.

Engine oil requirementsEJU43951Engine oilECJ00282
Use only 4-stroke engine oil. Usage of 2-
stroke engine oil could result in severe en-
gine damage.
Why Yamalube
YAMALUBE oil is a Genuine YAMAHA Part
born of the engineers’ passion and belief that
engine oil is an important liquid engine com-
ponent. We form teams of specialists in the
fields of mechanical engineering, chemistry,
electronics and track testing, and have them
develop the engine together with the oil it will
use. Yamalube oils take full advantage of the
base oil’s qualities and blend in the ideal bal-
ance of additives to make sure the final oil
clears our performance standards. Thus,
Yamalube mineral, semisynthetic and syn- thetic oils have their own distinct characters
and value. Yamaha’s experience gained over
many years of research and development
into oil since the 1960’s helps make
Yamalube the best choice for your Yamaha engine. Checking the engine oil level
EWJ00341
Engine oil is extremely hot immediately af-
ter the engine is turned off. Coming in con-
tact with or getting any engine oil on your
clothes could result in burns.
ECJ00392
Do not run the engine with too much or
not enough oil in the oil tank, otherwise
the engine could be damaged.
Make sure that debris and water do not
enter the oil tank filler hole. Debris and
water in the engine oil can cause serious
engine damage.
TIP:
When checking the engine oil level on land,
the engine must be running while water is
being supplied to the cooling water pas-
sages. (See “Flushing the cooling water
passages” on page 92 for information on
supplying water.)
When checking the engine oil level on wa-
ter, moor the watercraft so that it will not
drift away.
To check the engine oil level:
(1) With the engine stopped, place the wa- tercraft in a precisely level position on
land or launch the watercraft.
(2) Look in all directions, and then start the engine. (See page 79 for information on
starting the engine.)
(3) Run the engine at idling speed for 6 min- utes or more. Run the engine an addi-
tional 5 minutes if the ambient
temperature is 20 °C (68 °F) or less.
(4) Stop the engine.
(5) Remove the seats. (See page 54 for seat removal and installation procedures.)
Recommended engine oil:
YAMALUBE 4W or 4-stroke motor oil
Recommended engine oil type: SAE 10W-30, 10W-40, 20W-40,

(6) Loosen the oil tank filler cap and removeit, and then wipe the attached dipstick
clean.
(7) Screw the oil tank filler cap into the filler hole until it stops. Remove the oil tank
filler cap again and make sure that the
engine oil level is between the minimum
and maximum level marks.
(8) If the engine oil level is significantly above the maximum level mark, consult
a Yamaha dealer. If the engine oil level is
below the minimum level mark, slowly
add engine oil.
(9) Repeat steps 6–8 until the engine oil is at the proper level.
(10) Securely install the oil tank filler cap and turn it until it stops. (11) Securely install the seats in their original
positions.

Perform the pre-launch checks in the pre-op-
eration checklist while the watercraft is on
land.
To perform the pre-launch checks:
(1) Remove the seats and seat storagecompartment. (See page 54 for seat re-
moval and installation procedures and
page 59 for information on the seat stor-
age compartment.)
(2) Perform the checks and make sure that there are no malfunctioning items or oth-
er problems.
(3) After completing these checks, securely install the seat storage compartment and
seats in their original positions.
EJU32334Engine compartment checkEWJ00462
Failure to ventilate the engine compart-
ment could result in a fire or explosion. Do
not start the engine if there is a fuel leak.
Ventilate the engine compartment. Leave the
engine compartment open for a few minutes
to allow any fuel vapors to escape.
Make sure that there is no damage inside the
engine compartment.
EJU34215Fuel system checksEWJ00382
Leaking fuel can result in fire or explosion.
Check for fuel leakage regularly.
If any fuel leakage is found, the fuel sys-
tem must be repaired by a qualified me-
chanic. Improper repairs can make the
watercraft unsafe to operate.
Make sure that there is no damage, leakage,
or other problem in the fuel system.
Check:
Fuel filler cap and seal for damage
Fuel tank for damage and leakage
Fuel hoses and joints for damage and leak-
age
Fuel tank breather hose for damage and
leakage
EJU36875Fuel level check
Check the fuel level in the fuel tank.
Add fuel if necessary. (See page 62 for infor-
mation on filling the fuel tank.)
EJU32424Water separator check

Post-operation careEWJ00331
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.
EJU46370Flushing the cooling water passagesECJ01311
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. (See page 54 for seat removal and installation procedures.) (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 seats in their original po- sitions.
EJU43840Cleaning the watercraft
(1) Remove the seats. (See page 54 for seatremoval and installation procedures.)
(2) If the watercraft will be stored for a week or more, rustproof the internal engine
components to help prevent corrosion. (See page 96 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 66 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.
EJU3368BBattery 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.
