Enjoy your watercraft
responsibly
You share the areas you enjoy when riding
your watercraft with others and with nature.
So your enjoyment includes a responsibility to
treat these other people, and the lands, wa-
ters, and wildlife with respect and courtesy.
Whenever and wherever you ride, think of
yourself as the guest of those around you. Re-
member, for example, that the sound of your
watercraft may be music to you, but it could be
just noise to others. And the exciting splash of
your wake can make waves others won’t en-
joy.
Avoid riding close to shoreline homes and wa-
terfowl nesting areas or other wildlife areas,
and keep a respectful distance from fisher-
men, other boats, swimmers, and populated
beaches. When travel in areas like these is
unavoidable, ride slowly and obey all laws.
Proper maintenance is necessary to ensure
that the exhaust emission and sound levels of
your watercraft will continue to be within regu-
lated limits. You have the responsibility to
make sure that the recommended mainte-
nance in this owner’s/operator’s manual is
carried out.
Remember, pollution can be harmful to the
environment. Do not refuel or add oil where a
spill could cause damage to nature. Remove
your watercraft from the water and move it
away from the shoreline before refueling. And
keep your surroundings pleasant for the peo-
ple and wildlife that share the waterways:
don’t litter!
When you ride responsibly, with respect and
courtesy for others, you help ensure that our
waterways stay open for the enjoyment of a
variety of recreational opportunities.

EJU31141Remote control transmitter (for VX
Deluxe/VX Cruiser)
The Yamaha Security System and low-RPM
mode settings are selected using the remote
control transmitter. (See “Yamaha Security
System and low-RPM mode” on page 32 forinformation on using the remote control trans-
mitter.)
CAUTION:
ECJ00020
The Yamaha Security System and low-
RPM mode settings can only be selected
using the remote control transmitter. Ob-
serve the following precautions to protect
your remote control transmitter:

Store the remote control transmitter
carefully so it will not be lost. When op-
erating the watercraft, use the transmit-
ter holder in the glove compartment. If
you accidentally lose your remote con-
trol transmitter, contact a Yamaha deal-
er.

While the remote control transmitter has
been designed for use in wet environ-
ments, it should not be operated under-
water or submerged for an extended
length of time. If it gets wet, dry it with a
soft, dry cloth.

Keep the remote control transmitter
away from high temperatures and do not
place it in direct sunlight.

Do not drop the remote control transmit-
ter, subject it to strong shocks, or place
any heavy items on it.

Use a soft, dry cloth to clean the trans-
mitter. Do not use detergent, alcohol, or
other chemicals.

ing (OTS) system.
EJU31380Yamaha Security System and low-
RPM mode (for VX Deluxe/VX Cruiser)
This watercraft is equipped with a remote con-
trol transmitter that is used to select the secu-
rity system and low-RPM mode settings.
Since the watercraft is programmed to recog-
nize the internal code from this transmitter

help and convenience in operating the water-
craft.
CAUTION:
ECJ00071
Do not run the engine for more than 15
seconds without supplying water or over
4000 r/min on land when checking the op-
eration of the meter, otherwise the engine
could overheat.
NOTE:

When the engine is started, all displays light
up for 2 seconds, and then the meter starts
to operate normally.

The current display will continue to operate
for 25 seconds after the engine stops.

The engine speed (r/min) is displayed by seg-
ments. Each segment indicates a 250 r/min
increment.
EJU31500Speedometer

The fuel level meter has eight segments
which show the amount of fuel remaining in
the fuel tank.
NOTE:
The fuel level is most accurate when the wa-
tercraft is sitting level on a trailer or in the wa-
ter.
EJU31550Hour meter/voltmeter
NOTE:
To switch the display between the hour meter
and the voltmeter, push the select button for
at least 1 second after the meter is displayed
for more than 10 seconds.
Hour meter
The hour meter is provided to make it easy to
follow the maintenance schedule.The meter shows the hours of engine opera-
tion that have elapsed since the watercraft
was new.
Voltmeter
The voltmeter is provided to display the volt-
age of the battery.
When the battery voltage is normal, the volt-
meter displays approximately 12 volts.
If the battery voltage is less than 8.0 volts,
“LO” is displayed on the voltmeter and if the
voltage is above 18.1 volts, “HI” is displayed
on the voltmeter. If “HI” or “LO” is displayed,
return to shore and, if necessary, have a
Yamaha dealer check the charging system
and the battery.
EJU31560Fuel level warning indicator
If the fuel remaining in the fuel tank drops to
about 13 L (3.4 US gal, 2.9 Imp gal), the low-
est two fuel level segments, the fuel level
warning indicator, and the “WARNING” light
begin to blink. The buzzer also starts sound-
ing intermittently.
If this occurs, refill the fuel tank as soon as
possible.
The warning signals will be cleared when the
engine is restarted after the fuel tank is re-
filled.

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)
