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.
EJU30930
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 re-
leasing the throttle lever. The OTS system
assists in turning by continuing to supply
some thrust while the watercraft is deceler-
ating, but you can turn more sharply if you
apply throttle while turning the handlebars.
The OTS system does not function below
planing speeds or when the engine is off.
Once the engine slows down, the watercraft
will no longer turn in response to handlebar
input until you apply throttle again or you
reach trolling speed.
Practice turning in an open area without ob-
stacles until you have a good feel for this
maneuver.

This watercraft is water-jet propelled. 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” position. You are in ei-
ther “forward” or “reverse”, depending upon
the shift lever position (for VX Deluxe/VX
Cruiser).

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 im-
pact the handlebars.
This could increase the risk of back/spinal
injury (paralysis), facial injuries, and broken

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.

NOTE:

If the cooling water passages are dry, it will
take about 60 seconds for the water to
reach the outlet after the engine is started.

Water discharge may not be constant at
idle, therefore, open the throttle a little to
check that water discharges properly.
EJU31260Steering system
Your watercraft can be steered by turning the
handlebars in the direction you wish to travel.
When the handlebars are turned, the angle of
the jet thrust nozzle is changed, and the direc-
tion of the watercraft is changed accordingly.
Since the strength of the jet thrust determines
the speed and degree of a turn, throttle must
always be applied when attempting a turn, ex-
cept at trolling speed.This model is equipped with the Yamaha En-
gine Management System (YEMS) that in-
cludes an off-throttle steering (OTS) system.
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 sharply if you apply throttle
while turning the handlebars.
The OTS system does not function below
planing speeds or when the engine is off.
Once the engine slows down, the watercraft
will no longer turn in response to handlebar in-
put until you apply throttle again or you reach
trolling speed.
EJU31300Shift lever (for VX Deluxe/VX Cruiser)
The shift lever is located on the starboard
(right) side of the watercraft and is used to
control the reverse gate, which allows the wa-
tercraft to move in reverse or forward.
When the shift lever is in the reverse position,
the watercraft can be launched from a trailer,
or backed up out of tight spots where you can-
not turn around easily.
To shift into reverse:
(1) Release the throttle lever and let the en-
gine speed return to idle.
(2) Pull the shift lever toward you.

EJU31370Yamaha Engine Management System
(YEMS)
This model is equipped with an integrated,
computerized management system that con-
trols and adjusts ignition timing, fuel injection,
engine diagnostics, and the off-throttle steer-
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
only, the security system setting can only be
changed with this transmitter. If you lose the
remote control transmitter or it does not oper-
ate properly, contact a Yamaha dealer.
EJU31390Yamaha Security System (for VX Deluxe/
VX Cruiser)
The Yamaha Security System functions to
help prevent unauthorized use or theft of the
watercraft. The engine cannot be started if the
security system is in the lock mode. The en-
gine can only be started in the unlock mode.
EJU36102Yamaha Security System lock and unlock
modes (for VX Deluxe/VX Cruiser)

EJU32630Shift lever and reverse gate (for VX Deluxe/
VX Cruiser)
Check the shift lever and reverse gate for
proper operation.
Make sure that the reverse gate goes down
completely when the shift lever is pulled up.
Also, make sure that the reverse gate goes up
completely when the shift lever is pushed
down.
WARNING
EWJ00480

Make sure that the throttle lever is com-
pletely released and that the engine is at
idle before shifting into reverse.

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.

Use reverse for slow-speed maneuver-
ing only.

Make sure that there are no obstacles or
people behind you before shifting into
reverse.

Do not touch the reverse gate while the
shift lever is being operated, otherwise
you could be pinched.
EJU32650Jet intake
Carefully check the jet intake for weeds, de-
bris, or anything else that might restrict the in-
take of water. If the jet intake is clogged,
cavitation could occur, reducing jet thrust, and
possibly damaging the jet pump.
In some cases, the engine may overheat be-
cause of lack of cooling water, and damage to
the engine could result. Cooling water is fed to
the engine by the jet pump. (See page 82 for
jet intake cleaning procedures.)
WARNING
EWJ00470

Keep away from the intake grate while
the engine is on. Items such as long hair,
loose clothing, or PFD straps can be-
come entangled in moving parts, result-
ing in severe injury or drowning.

Stop the engine and remove the clip
from the engine shut-off switch before
removing any debris or weeds, which
