EJU31385Yamaha 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 sys-
tem is selected. The engine can only be start-
ed 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.
EJU36107Yamaha 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 mul-
tifunction information center. (See page 33
for information on the multifunction informa-
tion 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 per-
form the initial operation, and then the set-
ting 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,

will not start. Also, the starter motor could
be damaged.
[ECJ01041]
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.)
EJU31212Throttle 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.
EJU31262Steering system
By turning the handlebars in the direction you
wish to travel, the angle of the jet thrust noz-
zle is changed, and the direction of the water-
craft 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,
except 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.
EJU35975Cooling water pilot outlet
When the engine is running, some of the
cooling water that is circulated in the engine
is discharged from the cooling water pilot
outlet.
There is a cooling water pilot outlet on the
port (left) side of the watercraft. To check for
proper operation of the cooling system, make
sure that water is being discharged from the
cooling water pilot outlet. If water is not being
discharged from the outlet, stop the engine
and check the jet intake for clogging. (See
page 85 for information on the jet intake.)
TIP:
It will take about 60 seconds for the water
to reach the outlet after the engine is start-
ed.
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.
EJU40323Water 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.

the maximum engine speed to approximately
90% of the maximum engine speed in the
normal mode.
The Low RPM Mode can only be activated
and deactivated by operating the remote
control transmitter that is included with this
watercraft. (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 in-
formation on the mult ifunction information
center.)
TIP:
If the remote control transmitter is operated
while the multifunction information center is
in the standby state, the center performs the
initial operation, and then the setting is se-
lected.
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”
indicator 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.
