Hazard information
Never start the engine or let it run for any
length of time in an enclosed area. Exhaust
fumes contain carbon monoxide, a color-
less, odorless gas that may cause loss of
consciousness and death within a short
time. Always operate the watercraft in an
open area.
Do not touch the hot oil tank, muffler, or en-
gine during or immediately after engine op-
eration; they can cause serious burns.
Do not place magnets or objects with a
strong magnetic force near the throttle le-
ver or RiDE lever (VX / VX DELUXE /
VX CRUISER / VX LIMITED). The electronic
throttle mechanism of the levers can be ad-
versely affected, which could cause loss of
control. In addition, do not place objects
susceptible to magnetic forces (i.e., credit
cards, watches, etc.) close to the throttle
lever or RiDE lever.

Watercraft characteristics
Jet thrust turns the watercraft. Releasing
the throttle lever completely produces only
minimum thrust. If you are traveling at
speeds above trolling, you will have rapidly
decreasing ability to steer without throttle.
This model is equipped with the Yamaha
Engine Management System (YEMS) that
includes an off-throttle steering (OTS) sys-
tem. It will activate at planing speeds
should you attempt to steer the watercraft
after releasing the throttle lever. The OTS
system assists in turning by continuing to
supply some thrust while the watercraft is
decelerating, but you can turn more sharp-
ly if you apply throttle while turning the han-
dlebars.
The OTS system does not function below
planing speeds or when the engine is off.
Once the engine slows down, the water-
craft will no longer turn in response to han-
dlebar input until you apply throttle again or
you reach trolling speed.
Practice turning in an open area without
obstacles until you have a good feel for this
maneuver.
VX-C: This watercraft is water-jet pro-
pelled. The jet pump is directly connected
to the engine. This means that jet thrust will
produce some movement whenever the
engine is running. There is no “neutral” po-
sition.
VX / VX DELUXE / VX CRUISER / VX
LIMITED: This watercra ft is water-jet pro-
pelled. The jet pump is directly connected
to the engine. This means that jet thrust will
produce some movement whenever the
engine is running and the “F” (forward) or
“R” (reverse) shift indicator is displayed.
When the “N” (neutral) shift indicator is dis-
played, the forward and reverse thrust are

Fuel requirementsEJU45311FuelEWJ00283
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.
ECJ00322
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.
TIP
This mark identifies the recommended fuel
for this watercraft as specified by European
regulation (EN228).
Check that the gasoline nozzle has the
same identifier when fueling.
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and gasohol containing meth-
anol.
Gasohol containing ethanol can be used if
the ethanol content does not exceed 10%
and the fuel meets the minimum octane rat-
ings. E-85 is a fuel blend containing 85% eth-
anol and therefore must not be used in this
watercraft. All ethanol blends containing
more than 10% ethanol can cause fuel sys-
tem damage or engine performance prob-
lems.
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.
Recommended fuel:
Regular unleaded gasoline with a mi-
nimum octane rating of86
(Pump octane number) = (R + M)/2
90 (Research octane number)
