Watercraft control functions EJU41390Remote control transmitter
(VX Deluxe / VX Cruiser)
The Yamaha Security System and Low RPM
Mode settings can be selected by operating
the remote control transmitter. (See page 26
for Yamaha Security System setting proce-
dures and page 31 for Low RPM Mode activa-
tion procedures.)
Since the watercraft is programmed to recog-
nize the internal code from this transmitter
only, the settings can only be selected with
this transmitter.
If you accidentally lose your remote control
transmitter or if it is not operating properly,
contact a Yamaha dealer.
When operating the watercraft, always keep
the transmitter with you, such as by storing itin the transmitter holder in the beverage hold-
er, so that it is not lost.
NOTICE
ECJ00752

The remote control transmitter is not
completely waterproof. Do not sub-
merge the transmitter or operate it un-
derwater. If the transmitter is
submerged, dry it with a soft, dry cloth,
and then check that it is operating prop-
erly. If the transmitter is not operating
properly, contact a Yamaha dealer.

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.

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.

will not start. Also, the starter motor could
be damaged.
[ECJ01040]
The engine will not start under any of the fol-
lowing conditions:

Clip is removed from the engine shut-off
switch.

Throttle lever is squeezed.

VX Deluxe / VX Cruiser: Lock mode of the
Yamaha Security System has been select-
ed. (See page 26 for Yamaha Security Sys-
tem setting procedures.)
EJU31211Throttle lever
The throttle lever increases the engine speed
when the lever is squeezed.
The throttle lever returns automatically to its
fully closed (idle) position when released.
EJU31261Steering system
By turning the handlebars in the direction you
wish to travel, the angle of the jet thrust nozzle
is changed, and the direction 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 sys-
tem 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.
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.

EJU31417Low RPM Mode (VX Deluxe /
VX Cruiser)
The Low RPM Mode is a function that limits
the maximum engine speed to approximately
90% of the maximum engine speed in the nor-
mal mode.
The Low RPM Mode can only be activated
and deactivated by operating the remote con-
trol transmitter that is included with this water-
craft. (See page 25 for information on the
remote control transmitter.)
TIP:
The Low RPM Mode can only be activated
when the engine is stopped in the unlock
mode of the Yamaha Security System.
Activating and deactivating the Low RPM
Mode
Activation of the Low RPM Mode will be con-
firmed by the number of beeps when the re-
mote control transmitter is operated, and by
the “L-MODE” indicator light of the multifunc-
tion information center. (See page 33 for infor-
mation on the multifunction information
center.)
TIP:
If the remote control transmitter is operated
while the multifunction information center is in
the standby state, the center performs the ini-
tial operation, and then the setting is selected.
To activate the Low RPM Mode:
Push the “L-Mode” (unlock) button on the re-
mote control transmitter for more than 4 sec-
onds. Once the beeper sounds three times
and the “SECURITY” indicator light blinks
three times, then comes on, the “L-MODE” in-
dicator light comes on and the Low RPM
Mode is activated.
TIP:
If the Low RPM Mode is activated immediate-
ly after the information display turns off, the
“L-MODE” indicator light will not come on. The

various watercraft information.
Multifunction information center initial op-
eration
When the multifunction information center is
activated, all of the display segments come
on. After 2 seconds, the warning indicators in
the information display go off, and then the
center starts to operate normally.
If only the multifunction information center is
activated, the “WARNING” indicator light
blinks once.
TIP:
VX Deluxe / VX Cruiser: The “SECURITY” in-
dicator light also comes on as part of the initial
operation.
The “SECURITY” indicator light will go off
when the engine is started.
Multifunction information center standby
state
If the multifunction information center does
not receive any operation input within 25 sec-onds after the engine stops, the center will
turn off and enter a standby state. When the
engine is started again, the displays return to
their state before the center turned off, and
then the center starts to operate normally.
