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.
EJU30934
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.

VX Sport: 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 en-
gine is running. There is no “neutral” posi-
tion.

VX Deluxe / VX Cruiser: 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 either “for-
ward” or “reverse”, depending upon the
shift lever position.

VX Deluxe / VX Cruiser: Do not use the re-
verse function to slow down or stop the wa-

EJU31384Yamaha Security System (VX Deluxe /
VX Cruiser)
The Yamaha Security System functions to
help prevent unauthorized use or theft of the
watercraft. The lock and unlock modes of the
security system can be selected by operating
the remote control transmitter that is included
with this watercraft. The engine cannot be
started if the lock mode of the security system
is selected. The engine can only be started if
the unlock mode is selected. (See page 25 for
information on the remote control transmitter.)
TIP:
The Yamaha Security System settings can
only be selected while the engine is stopped.
EJU36106Yamaha Security System settings
The Yamaha Security System settings will be
confirmed by the number of beeps when the
remote control transmitter is operated, and by
the “SECURITY” indicator light of the multi-
function information center. (See page 33 for
information on the multifunction information
center.)
TIP:

The beeper sounds two times for the nor-
mal operation mode or three times for the
Low RPM Mode. (See page 31 for Low
RPM Mode activation procedures.)

If the remote control transmitter is operated
while the multifunction information center is
in the standby state, the center will performthe initial operation, and then the setting is
selected.
To select the lock mode:
Push the lock button on the remote control
transmitter briefly. The beeper sounds once
and the “SECURITY” indicator light blinks
once, then goes off. This indicates the lock
mode is selected.
To select the unlock mode:
Push the “L-Mode” (unlock) button on the re-
mote control transmitter briefly. The beeper
sounds two or three times and the “SECURI-
TY” indicator light blinks two or three times,
then comes on. This indicates the unlock
mode is selected.

EJU31152Engine stop switch“”
The engine stop switch (red button) stops the
engine when the switch is pushed.
EJU31163Engine shut-off switch“”
The engine shut-off switch automatically
stops the engine when the clip, on the end of
the engine shut-off cord (lanyard), is removed
from the switch, such as if the operator falls off
the watercraft.
Insert the clip under the engine shut-off switch
before starting the engine.
When the engine is not running, remove the
clip from the engine shut-off switch to preventaccidental starting or unauthorized operation
by children or others.
EJU41650Start switch“”
NOTICE
ECJ01310
Do not run the engine over 4000 r/min on
land. Also, do not run the engine for more
than 15 seconds without supplying water,
otherwise the engine could overheat.
The start switch (green button) starts the en-
gine when the switch is pushed.
Release the start switch as soon as the en-
gine starts to run. If the engine does not start
in 5 seconds, release the start switch, wait 15
seconds, and then try again. NOTICE: Never
push the start switch while the engine is
running. Do not operate the start switch
for more than 5 seconds, otherwise the
battery will be discharged and the engine

in response to handlebar input until you apply
throttle again or you reach trolling speed.
EJU35974Cooling water pilot outlet
When the engine is running, some of the cool-
ing water that is circulated in the engine is dis-
charged from the cooling water pilot outlet.
There is a cooling water pilot outlet on the port
(left) side of the watercraft. To check for prop-
er operation of the cooling system, make sure
that water is being discharged from the cool-
ing water pilot outlet. If water is not being dis-
charged from the outlet, stop the engine and
check the jet intake for clogging. (See page
84 for information on the jet intake.)
TIP:

It will take about 60 seconds for the water to
reach the outlet after the engine is started.

Water discharge may not be constant when
the engine is running at idling speed. If this
occurs, apply a little throttle to make sure
that water discharges properly.
EJU40322Water separator
The water separator prevents water from en-
tering the fuel tank by collecting any water that
has entered the fuel tank breather hose if the
watercraft was capsized.If water has collected in the water separator,
drain it by loosening the drain screw.
To drain water from the water separator:
(1) Place a drain pan or dry cloth under the
water separator.
(2) Gradually loosen the drain screw to drain
the water. Catch the draining water in the
drain pan or soak it up with the dry cloth
so that it does not spill into the engine
compartment. If any water spills into the
watercraft, be sure to wipe it up with a dry
cloth.
(3) Securely tighten the drain screw until it
stops.

EJU40520Reverse system (VX Deluxe /
VX Cruiser)
WARNING
EWJ01230

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.

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.
When the shift lever is moved to the reverse
position, the reverse gate lowers and deflects
the water jet being discharged from the jet
thrust nozzle. This allows the watercraft to
move in reverse.
To shift into reverse:
(1) Release the throttle lever and let the en-
gine speed return to idle.
(2) Pull the shift lever rearward until it stops
in the reverse position. The reverse gatewill lower and the watercraft will start
moving in reverse at trolling speed.
To shift into forward:
(1) Release the throttle lever and let the en-
gine speed return to idle.
(2) Push the shift lever forward until it stops
in the forward position. The reverse gate
will rise and the watercraft will start mov-
ing forward at trolling speed.
