EJU30870
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

Make sure that the rope is not looped
around anything.
After checking that the skier is ready and
that there is no traffic or other obstacles, ap-
ply enough throttle to raise the skier.

Make smooth, wide turns. The watercraft is
capable of very sharp turns, which could ex-
ceed the abilities of the skier. Keep the skier
at least 50 m (150 ft), about twice the dis-
tance of a standard ski rope, from any po-
tential hazard.

Be alert to the hazard of the ski rope handle
snapping back at the watercraft when the
skier falls or is unable to get up on the skis.

Towing heavy or bulky objects other than
skiers, such as another boat or watercraft,
can cause loss of steering control and cre-
ate a hazardous condition. If you must tow
another boat in an emergency situation, op-
erate slowly and cautiously.
EJU30970
Safe boating rules
Your Yamaha watercraft is legally considered
a powerboat. Operation of the watercraft must
be in accordance with the rules and regula-
tions governing the waterway on which it is
used.

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 youcan 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.
WARNING
EWJ00030

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.

Be sure to connect the breather hose to
the battery. Fire or explosion could re-
sult if the breather hose is damaged, ob-
structed, or not connected properly.
Make sure that the battery is securely held in
place.
EJU32540Fire extinguisher
Check that there is a full fire extinguisher on
board.
The fire extinguisher holder and cover are lo-
cated in the front storage compartment.
To store the fire extinguisher, unhook the
band and remove the cover. Place the fire ex-
tinguisher in the holder, and then place the
cover over the fire extinguisher. Fasten the
cover and the fire extinguisher with the band
securely.
NOTE:

To check the fire extinguisher, see the in-
structions supplied by the fire extinguisher
manufacturer. Always keep the fire extin-
guisher secured in the holder with its cover
in place.

Always carry a fire extinguisher on board. A
fire extinguisher is not standard equipment
with this watercraft. If you do not have one,
contact a Yamaha dealer or a fire extin-
guisher dealer to obtain one meeting the
proper specifications.
EJU32590Throttle lever
Check the throttle lever for proper operation.
Squeeze and release the throttle lever several
times to make sure that there is no hesitation
in its travel. It should be smooth over the com-
plete range and spring back to the idle posi-
tion when released.
WARNING
EWJ00490
Before starting the engine, always check
the operation of the throttle lever.

ride plate while pushing down on the gun-
wale with your right hand or foot.
NOTE:
If the port (left) side of the capsized watercraft
is tilting up, push down on the gunwale so that
the port (left) side is down before turning the
watercraft clockwise.
CAUTION:
ECJ00540
Do not turn the watercraft over counter-
clockwise, otherwise water can enter the
engine, which can result in severe dam-
age.
(3) Start the engine and operate the water-
craft to discharge any water remaining in
the engine compartment. (If the engine
does not start, see “Towing the water-
craft” on page 83 or “Submerged water-
craft” on page 83.)
CAUTION:
ECJ00550
Do not operate the engine at full throttle
for at least 1 minute after the engine has
been restarted. Excessive water in the
bilge can splash into the engine, which
can result in severe damage.
NOTE:
To efficiently discharge water from the engine
compartment, operate the watercraft as
straight as possible and above planing speed
for at least 2 minutes.
EJU33250Turning the watercraft
Steering control depends on the combination
of handlebar position and the amount of throt-
tle.
Water sucked in through the intake grate is
pressurized by the impeller in the jet pump. As
the pressurized water is expelled from the
pump through the jet thrust nozzle, it creates
thrust to move and steer the watercraft. The
higher the engine speed, the more thrust pro-
duced.
The amount of jet thrust, in addition to the po-
sition of the handlebars, determines how
sharply you turn.
A. More throttle produces higher thrust, so
the watercraft will turn more sharply.
UF1K73E0.book Page 58 Wednesday, July 11, 2007 9:15 AM

Operation
59
B. Less throttle produces lower thrust, so
the watercraft will turn more gradually.
C. 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. You may still have some
turning ability immediately after releasing
the throttle lever, but once the engine
slows down, the watercraft will no longer
respond to handlebar input until you ap-
ply throttle again or you reach trolling
speed.
At trolling speed, the watercraft can be
turned gradually by handlebar position
alone using just the amount of thrust
available at idle.D. If the engine is stopped while riding, there
is no thrust. The watercraft will go straight
even though the handlebars are turned.
You need throttle to steer.
WARNING
EWJ00770

Do not release the throttle lever when
trying to steer away from objects—you
need throttle to steer. A collision could
result in severe injury or death.

When operating at higher speeds, make
gradual turns or slow down before turn-
ing. Sharp high-speed turns may cause
the watercraft to slide sideways or spin,
throwing the operator and passengers
overboard, which could cause an injury.
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 (see condition C above).
The OTS system assists in turning by continu-
ing to supply some thrust while the watercraft
is decelerating, but you can turn more sharply
if you apply throttle while turning the handle-
bars. The OTS system does not function be-
low planing speeds or when the engine is off.
Once the engine slows down, the watercraft
will no longer turn in response to handlebar in-
