WARNING
EWJ00283
Gasoline and gasoline vapors are ex-
tremely flammable. To avoid fires and
explosions and to reduce the risk of in-
jury when refueling, follow these in-
structions.
Gasoline is poisonous and can cause in-
jury or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline, inhale a
lot of gasoline vapor, or get some gaso-
line in your eyes, see your doctor imme-
diately. If gasoline spills on your skin,
wash with soap and water. If gasoline
spills on your clothing, change your
clothes.
NOTICE
ECJ01870
Do not use leaded gasoline. Leaded
gasoline can seriously damage the en-
gine.
Avoid getting water and contaminants in
the fuel tank. Contaminated fuel can
cause poor performance and engine
damage. Use only fresh gasoline that
has been stored in clean containers.
Use only gasoline with a minimum pump
octane number of 91 or a minimum re-
search octane number of 95. Low-oc-
tane gasoline can seriously damage the
engine.
Your Yamaha engine has been designed to
use premium unleaded gasoline with a pump
octane number [(R+M)/2] of 91 or higher, or a
research octane number of 95 or higher. Ifknocking (or pinging) occurs, use a gasoline
of a different brand.
TIP:
This mark identifies the recommended fuel
for this watercraft as specified by European
regulation (EN228).
Check that gasoline nozzle has the same
identifier when fueling.
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and that containing methanol.
Gasohol containing ethanol can be used if
ethanol content does not exceed 10% and
the fuel meets the minimum octane ratings.
E-85 is a fuel blend containing 85% ethanol
and therefore must not be used in this water-
craft. All ethanol blends containing more than
10% ethanol can cause fuel system damage
or engine performance problems.
Yamaha does not recommend gasohol con-
taining methanol because it can cause fuel
system damage and engine performance
problems.Recommended fuel:
Premium unleaded gasoline with a
minimum octane rating of
91
(Pump octane number) = (R + M)/2
95 (Research octane number)

To fill the fuel tank:
(1) Before refueling, stop the engine. Do not
stand 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 49 for seat removal
and installation procedures.)
(4) Pull the hood latch rearward, and then lift
up the rear of the hood.
(5) Loosen the fuel filler cap and remove it.
(6) Slowly add fuel to the fuel tank.(7) 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.
(8) Wipe up any spilled fuel immediately with
a dry cloth.
(9) Securely install the fuel filler cap by tight-
ening it until it clicks.
(10) Push the rear of the hood down to se-
curely lock it in place. Make sure that thefuel filler cap and the hood are securely
closed before using the watercraft.
(11) Securely install the seats in their original
positions.

Pre-operation check pointsEJU42383Pre-launch checks
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 removable water-
tight storage compartment. (See page 49
for seat removal and installation proce-
dures and page 56 for information on the
removable watertight storage compart-
ment.)
(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 removable watertight storage
compartment and seats in their original
positions.
EJU32334Engine compartment check
WARNING
EWJ00462
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 checks
WARNING
EWJ00382
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 59 for infor-
mation on filling the fuel tank.)

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 56 for information on the
removable watertight storage compart-
ment.)
(3) Open the stern storage compartment.
(See page 55 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-

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 89 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 90 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.
