WARNING
EWJ00282

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
ECJ00321

Do not use leaded gasoline. Leaded gas-
oline can seriously damage the engine.

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.
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 thefuel meets the minimum octane ratings. E-85
is a fuel blend containing 85% ethanol and
therefore must not be used in this watercraft.
All ethanol blends containing more than 10%
ethanol can cause fuel system damage or en-
gine performance problems.
Yamaha does not recommend gasohol con-
taining methanol because it can cause fuel
system damage and engine performance
problems.
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 seat, and then check the fuel
level. (See page 37 for seat removal and
installation procedures.)
(4) Loosen the fuel filler cap and remove it.
(5) Slowly add fuel to the fuel tank. Recommended fuel:
Regular unleaded gasoline with a
minimum octane rating of
86
(Pump octane number) = (R + M)/2
90 (Research octane number)

(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 seat in its original po-
sition.

Engine oil requirements EJU41542Engine oil
NOTICE
ECJ00281
Use only 4-stroke engine oil. Usage of 2-
stroke engine oil could result in severe en-
gine damage.
Checking the engine oil level
WARNING
EWJ00340
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.
NOTICE
ECJ00391

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 passag-
es. (See “Flushing the cooling water pas-
seges” on page 70 for information on
supplying water.)

When checking the engine oil level on wa-
ter, moor the watercraft so that it will not drift
away. Fuel tank capacity:
60 L (15.9 US gal, 13.2 Imp.gal)

To check the engine oil level:
(1) With the engine stopped, place the water-
craft in a precisely level position on land
or launch the watercraft.
(2) Look in all directions, and then start the
engine. (See page 59 for information on
starting the engine.)
(3) Run the engine at idling speed for 6 min-
utes or more. Run the engine an addition-
al 5 minutes if the ambient temperature is
20 °C (68 °F) or less.
(4) Stop the engine.
(5) Remove the seat. (See page 37 for seat
removal and installation procedures.)
(6) Loosen the oil tank filler cap and remove
it, 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 fill-
er cap again and make sure that the en-gine 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 seat in its original po-
sition.

Draining the bilge water
NOTICE
ECJ01301
Do not run the engine at full throttle when
bilge water remains in the engine compart-
ment. The bilge water can splash into the
engine, which can result in severe dam-
age.
EJU40033Draining the bilge water on land
To drain the bilge water on land:
(1) Loosen the stern drain plugs and remove
them.
(2) Raise the bow of the watercraft, such as
by placing the watercraft on a slope, to
drain the bilge water from the engine
compartment.
(3) After the bilge water has drained from the
stern drain plug holes, wipe up any re-maining moisture in the engine compart-
ment with a dry cloth.
(4) Securely install the stern drain plugs by
tightening them until they stop. NOTICE:
Before installing the stern drain plugs,
clean the drain plug threads to remove
any foreign materials, such as dirt or
sand. Otherwise, the stern drain plugs
could be damaged, allowing water to
enter the engine compartment. Make
sure that the stern drain plugs are
tightened securely before launching
the watercraft. Otherwise, water may
flood the engine compartment and
cause the watercraft to submerge.
[ECJ00361]
EJU40534
Draining the bilge water on water
A small quantity of bilge water will remain in
the engine compartment even after the bilge
water is drained on water. To completely drain
the bilge water, remove the watercraft from
the water and drain the bilge water on land.
Jet vacuum bilge draining system
While the watercraft is operating, bilge water
in the engine compartment is drawn in by the
vacuum that is generated in the jet pump and
discharged from the watercraft through the jet
thrust nozzle.
To drain the bilge water on water:
Operate the watercraft as straight as possible
and above planing speed for at least 2 min-
utes. NOTICE: Do not run the engine at full
throttle for at least 1 minute after the en-
gine has been restarted. Bilge water in the
engine compartment can splash into the

age.
[ECJ00553]EJU33464Transporting on a trailer
When transporting the watercraft on a trailer,
secure the tie downs to the trailer through the
bow eye and stern eyes. NOTICE: Do not at-
tach ropes or tie downs to any part of the
watercraft other than the bow eye and
stern eyes to secure the watercraft to the
trailer. Otherwise, the watercraft may be
damaged. Wrap the ropes or tie downs
with towels or rags where they touch the
body of the watercraft to avoid scratches
or damage. VX Deluxe / VX Cruiser: Do not
transport the watercraft with the shift lever
in the reverse position. Otherwise, the re-
verse gate may hit an obstacle, which
could cause damage.

Engine break-in
NOTICE
ECJ00431
Failure to perform the engine break-in
could result in reduced engine life or even
severe engine damage.
The engine break-in is essential to allow the
various components of the engine to wear
and polish themselves to the correct operat-
ing clearances. This ensures proper perfor-
mance and promotes longer component life.
To perform the engine break-in:
(1) Check the engine oil level. (See page 44
for information on checking the engine oil
level.)
(2) Launch the watercraft and start the en-
gine. (See page 59 for information on
starting the engine.)
(3) For the first 5 minutes, operate with the
engine at idling speed.
(4) For the next 30 minutes, operate with the
engine speed below 5000 r/min.
(5) For the next 1 hour, operate with the en-
gine speed below 6500 r/min.
After the engine break-in is complete, the wa-
tercraft can be operated normally.
