To prevent accidental starting of the en-
gine or unauthorized use by children or
others, always remove the clip from the
engine shut-off switch when the engine
is not running.
EJU31190Start switch
Push the start switch (green button) to start
the engine.
NOTE:
The engine will not start when the lock mode
of the Yamaha Security System has been se-
lected (for VX Deluxe/VX Cruiser), the clip is
removed from the engine shut-off switch, or
the throttle lever is squeezed. (See page 32
for Yamaha Security System and low-RPM
mode selection procedures.)
EJU31210Throttle lever
Squeeze the throttle lever to increase engine
speed.
Release the throttle lever to decrease engine
speed or to return it to the idle position.
EJU35971Cooling water pilot outlet
This watercraft is equipped with a cooling wa-
ter pilot outlet.
When the engine is running, cooling water is
circulated in the engine, and then it is dis-
charged from the pilot outlet.
To check for proper operation of the cooling
system, check that water is being discharged
from the pilot outlet. If water is not being dis-
charged from the outlet, cooling water may
not be circulating in the engine. When this oc-
curs, stop the engine and check for the cause.
(See pages 36 and 82 for more information.)

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.

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.

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.
To shift into forward:
(1) Release the throttle lever and let the en-
gine speed return to idle.
(2) Push the shift lever away from you.
EJU31360Handgrip
The handgrip provides a handhold for board-
ing the watercraft and for a spotter when fac-
ing rearward.
WARNING
EWJ00020
Do not use the handgrip to lift the water-
craft. The watercraft could fall, which
could result in severe injury.
EJU34870Bow eye
The bow eye is located at the bow of the wa-
tercraft.
The bow eye is used to attach a rope to the
watercraft when transporting, mooring, or
towing it in an emergency.
EJU34880Stern eyes
The stern eyes are located at the stern of the
watercraft.
The stern eyes are used to attach a rope to
the watercraft when transporting or mooring it.

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)

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)

transmitter is pressed, the beeper soundsonce. This indicates the lock mode is selected
and the engine cannot be started.
The “SECURITY” indicator light comes on
when the security system is in the unlock
mode and goes off when the security system
is in the lock mode.
When the unlock button on the remote control
transmitter is pressed for a short time, the
beeper sounds two times for the normal mode
