Fuel and oil
This watercraft is equipped with a 4-stroke en-
gine. Conventional 2-stroke engine oil cannot
be used.
The engine utilizes an electronic fuel injection
system to deliver the optimal air-fuel ratio re-
quired by the engine. By ensuring the optimal
combustion conditions, this system is able to
increase startability and improve fuel econo-
my.
EJU31840Gasoline
WARNING
EWJ00430
GASOLINE AND ITS VAPORS ARE HIGH-
LY FLAMMABLE AND EXPLOSIVE!
Do not smoke when refueling, and keep
away from sparks, flames, and other
sources of ignition.
Stop the engine before refueling.
Refuel in a well-ventilated area with the
watercraft in a horizontal position.
Do not stand or sit on the watercraft
while refueling in case of fire.
Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.
Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level reaches approxi-
mately 50 mm (2 in) from the top of the
fuel tank. Fuel expands as it warms up
and could overflow if the fuel tank has
been overfilled. If temporarily leaving
the watercraft with a full fuel tank, do not
leave it in direct sunlight. Leave it in a
well-ventilated area with the watercraft
in a horizontal position.
Tighten the fuel tank filler cap securely
after refueling.
If you should swallow some gasoline, in-
hale a lot of gasoline vapor, or get gaso-
line in your eyes, get immediate medical
attention.
If any gasoline spills on your skin or
clothing, immediately wash the affected
area with soap and water and change
your clothes.
CAUTION:
ECJ00310
Use only fresh gasoline that has been
stored in clean containers.
EJU31860Gasohol
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.
Gasohol containing methanol is not recom-
mended by Yamaha because it can cause
fuel system damage and engine performance
problems.Recommended gasoline:
Regular unleaded gasoline with a mini-
mum octane rating of
86 (Pump octane number) = (R +
M)/2
90 (Research octane number)

steer away from a boat or other obstacle
that comes into your path.
For VX Deluxe/VX Cruiser:
Do not use the reverse function to slow
down or stop the watercraft as it could
cause you to lose control, be ejected, or
impact the handlebars.
EJU35960Beaching the watercraft
(1) Make sure that there are no boats, swim-
mers, or obstacles near the beach. Re-
lease the throttle lever about 100 m (330
ft) before you reach the intended beach-
ing area.
(2) Approach the beach slowly and stop the
engine before reaching land.
Remember, you need throttle to steer.
(3) Get off the watercraft and pull it up on the
beach.
CAUTION:
ECJ00490
Small pebbles, sand, seaweed, and other
debris can be sucked into the jet intake
and impair or damage the impeller. Always
stop the engine and get off the watercraft
before beaching it.
EJU36060Docking the watercraft
(1) Make sure that there are no boats, swim-
mers, or obstacles near the watercraft.
Reduce speed about 100 m (330 ft) away
from the dock.
(2) Slowly approach the dock and stop the
engine just before coming alongside it.
EJU33320Reverse on waterways (for VX Deluxe/
VX Cruiser)
Reverse can be used for slow-speed maneu-
vering when it is necessary to back up out of
tight spots where you cannot turn around. Re-
verse can be used to slow down or stop onlyduring slow-speed maneuvering, such as
when docking.
Once the engine is idling, shift into reverse
and gradually increase engine speed. Make
sure that there are no obstacles or people be-
hind you before shifting into reverse.
EJU33350Rough water operation
The force of landing after jumping can cause
a strong impact on both the watercraft and the
operator and passengers. It is possible for the
operator to hit his or her chest or jaw on the
watercraft or handlebars and be injured. The
passengers could also impact the watercraft
and be injured.
Do not operate the watercraft with your chin
right above the handlebars. In addition, the
operator and passengers should keep their
feet on the floor of the footwell.
Operating in rough water or jumping waves
can also crack the watercraft hull and deck,
and damage internal parts. Avoid operating in
rough water or bad weather conditions.

Post-operation care
To keep your watercraft in top shape, always
take it out of the water after using it and per-
form the following procedures. Leaving the
watercraft in the water for extended periods
will accelerate the rate of normal deterioration
of the jet unit components and hull finish. Ma-
rine organisms and corrosion are some of the
conditions that can adversely affect the life of
many watercraft components.
(1) Remove the watercraft from the water.
(2) Wash down the hull, handlebars, and jet
unit with fresh water.
(3) Remove the seat and check the engine
compartment for water. To drain excess
water, remove the stern drain plugs, and
then raise the bow of the watercraft
enough to allow the water in the bilge to
drain out.
NOTE:
This watercraft is equipped with an automatic
bilge draining system that removes water
from the engine compartment while you are
underway. However, some residual water will
remain.
(4) Place the watercraft in a horizontal posi-
tion.
(5) Flush the cooling system to prevent it
from clogging with salt, sand, or dirt. (See
page 66 for flushing procedures.)(6) Drain residual water from the exhaust
system by alternately squeezing and re-
leasing the throttle lever for 10 to 15 sec-
onds while the engine is running.
CAUTION:
ECJ00560
Do not run the engine for more than 15
seconds, otherwise the engine could over-
heat.
(7) If the watercraft will be stored for a week
or more, lubricate internal engine compo-
nents to help prevent corrosion. (See
page 67 for lubrication procedures.)
(8) Rinse the engine and engine compart-
ment with a small amount of water.
CAUTION:
ECJ00570
Do not use high-pressure water when rins-
ing the engine or engine compartment as
severe engine damage could result.
(9) Wipe the engine and engine compart-
ment dry with a clean cloth (repeat step 3,
if necessary).
(10) Wipe the hull, handlebars, and jet unit dry
with a clean cloth.
(11) Spray a rust inhibitor on metallic parts to
minimize corrosion.
(12) Allow the engine compartment to air dry
completely before installing the seat.

(4) Wax the hull with a non-abrasive wax.
(5) Wipe all vinyl and rubber components,
such as the seat and engine compart-
ment seals, with a vinyl protectant.
EJU33761
Maintenance and adjustments
Periodic inspection, adjustment, and lubrica-
tion will keep your watercraft in the safest and
most efficient condition possible. Safety is an
obligation of the watercraft owner. Proper
maintenance must be carried out to keep the
exhaust emission and sound levels within the
regulated limits. The most important points of
watercraft inspection, adjustment, and lubri-
cation are explained on the following pages.
See a Yamaha dealer for genuine Yamaha re-
placement parts and optional accessories de-
signed for your watercraft.
Remember, failures that are the result of the
installation of parts or accessories which are
not qualitatively equivalent to genuine
Yamaha parts are not covered by the limited
warranty.
Maintenance, replacement, or repair of the
emission control devices and system may
be performed by any marine SI engine re-
pair establishment or individual. Warranty
repair, however, must be performed at an
authorized Yamaha marine dealership.
WARNING
EWJ00310
Be sure to shut the engine off when you
perform maintenance unless otherwise
specified, otherwise an accident or inju-
ry could result from unexpected opera-
tion, moving parts, or electric shock. If
the owner is not familiar with watercraft
servicing, this work should be done by a
Yamaha dealer. Improperly serviced
components could fail or stop operating
correctly, which could result in an acci-
dent.
Modifications to this watercraft not ap-
proved by Yamaha may cause loss of
performance or excessive noise and ex-
haust emissions, or render it unsafe for
