Watercraft control functionsEJU45091Yamaha Security System (VX DELUXE / VX CRUISER / VX
LIMITED)
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 using the
engine lock screen of the multifunction infor-
mation center. The engine cannot be started
if the lock mode of the security system is se-
lected. The engine can only be started if the
unlock mode is selected.
TIP:
The Yamaha Security System setting can
only be selected while the engine is stopped.
EJU45870Yamaha Security System setting
The Yamaha Security System setting can be
confirmed by the lock or unlock mode indica-
tor on the multifunction information center.
To select the lock or unlock mode of the
Yamaha Security System:
(1) Stop the engine.
TIP:
The multifunction information center is turned
on, even if the engine start/stop switch is also
pushed briefly. (2) Select the lock or unlock mode indicator
on the multifunction information center.
(3) Input each digit of the 4-digit PIN, and then push the “OK” button of the touch-
pad control.
TIP:
The default setting for the PIN is “1234”. The
PIN can also be changed. (See page 48 for in-
formation on changing the PIN.)
(4) To select the lock mode of the YamahaSecurity System, select “ON”. To select
the unlock mode, select “OFF”.
(5) The beeper sounds once when the lock mode of the Yamaha Security System is
selected, and two times when the unlock
mode is selected.

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 engine start/stop switch (red button)
starts the engine when the switch is pushed
while the engine is stopped, and stops the
engine when the switch is pushed while the
engine is running.
Release the engine start/stop switch as soon
as the engine starts to run. If the engine does
not start in 5 seconds, release the engine start/stop switch, wait 15 seconds, and then
try again.
The engine will not start under any of the fol-
lowing conditions:
VX DELUXE / VX CRUISER / VX LIMITED:
Lock mode of the Yamaha Security System
has been selected. (See page 25 for
Yamaha Security System setting proce- dures.)

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 pre-
vent accidental starting or unauthorized op-
eration by children or others.

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 startin 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
will not start. Also, the starter motor could
be damaged.

EJU43342RiDE lever (VX / VX DELUXE /
VX CRUISER / VX LIMITED)
When the RiDE lever is squeezed, the reverse
gate lowers and the watercraft starts moving
in reverse. If the watercraft is moving forward,
the watercraft gradually slows down until it
stops, and then the watercraft starts moving
in reverse.
When the RiDE lever is released, it automati-
cally returns to its fully closed (idle) position
and the reverse gate moves to the neutral po-
sition.
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 107 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 thewater 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.

Make sure that there are no obstacles or
people behind you before shifting into
reverse.
Do not touch the reverse gate while the
RiDE lever is being operated, otherwise
you could be pinched.
If the RiDE lever and throttle lever are
being operated at the same time, do not
release only the RiDE lever. Otherwise,
the watercraft could accelerate more
quickly than expected, which may lead
to an accident.
The RiDE lever and throttle lever can be oper-
ated to change the forward or rearward
movement of the watercraft only when the
engine is running. When the RiDE lever is
squeezed, the reverse gate lowers and de-
flects the water jet being discharged from the
jet thrust nozzle so that the watercraft moves
in reverse or is in neutral. When the throttle le-
ver is squeezed, the reverse gate rises and
the watercraft moves forward.
TIP:
This model is equipped with a function
which limits the engine speed in reverse.
When the engine is started, the reverse
gate automatically moves to the neutral po-
sition.
To shift into reverse:
(1) Release the throttle lever.
(2) Squeeze the RiDE lever. The reverse gate will lower, the engine speed will in-
crease, the watercraft will start moving in reverse, and the “R” (reverse) shift indi-
cator will be displayed.
