EJU31191Start 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 29
for Yamaha Security System lock and unlock
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 33 and 80 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.

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)
The Yamaha Security System functions to
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)
The lock and unlock modes of this system can
only be selected while the engine is stopped.
When the lock button on the remote control
transmitter is pressed, the beeper sounds
once. 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 unlockmode 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
or three times for the low-RPM mode. The
“SECURITY” indicator light will come on and
the engine can be started. (See the items in
“Selecting the normal mode/low-RPM mode”
for operation mode information.)

EJU31412Selecting the normal mode/low-RPM
mode (for VX Deluxe/VX Cruiser)
The normal mode and low-RPM mode can
only be selected when the engine is stopped
in the unlock mode. Press the unlock button
on the remote control transmitter for more
than 4 seconds to switch between the normal
mode and the low-RPM mode.
Normal mode
If the beeper sounds twice, the normal mode
is activated.
The watercraft can be ridden normally.
Low-RPM mode
If the beeper sounds three times, the low-
RPM mode is activated and the “L-MODE” in-
dicator light comes on.
Maximum engine speed (r/min) in the low-
RPM mode is limited to approximately 90% of
the maximum engine speed in the normal
mode.
NOTE:

If neither the start switch nor the remote
control transmitter is operated within 25
seconds after the unlock button is pressed
to select the unlock mode, the multifunction
information center display and the “L-
MODE” indicator light will go off. If this oc-
curs, press the lock button on the transmit-
ter briefly to select the lock mode, press the
unlock button briefly to select the unlockmode, and then press the unlock button
again for more than 4 seconds to select the
normal mode or low-RPM mode.

While the engine is running, input from the
remote control transmitter is not received.
CAUTION:
ECJ00080
If the remote control transmitter does not
operate when its buttons are pressed, the
battery may be low. Have a Yamaha dealer
replace the battery.

Operation
WARNING
EWJ00510
Before operating your watercraft, become
familiar with all of the controls. Consult a
Yamaha dealer about any control or func-
tion that you do not fully understand. Fail-
ure to understand how the controls work
could cause an accident or prevent you
from avoiding an accident.
CAUTION:
ECJ00460
Make sure that the stern drain plugs are
tightened securely before launching the
watercraft.
EJU32781Engine break-in
The engine break-in period is essential to al-
low the various components of the engine to
wear and polish themselves to the correct op-
erating clearances. This ensures proper per-
formance and promotes longer component
life.
CAUTION:
ECJ00440
Be sure to check the engine oil level be-
fore operating the watercraft for the first
time. (See page 42 for engine oil checking
procedures.)
(1) Launch the watercraft and start the en-
gine. (See page 49 for engine starting
procedures.)
(2) For the first 5 minutes, run the engine at
trolling speed only. For the 30 minutes of
operation after that, keep the engine
speed below 5000 r/min. For the 1 hour of
operation after that, keep the engine
speed below 6500 r/min.
(3) Proceed with normal operation.
CAUTION:
ECJ00430
Failure to follow the engine break-in pro-
cedure could result in reduced engine life
or even severe engine damage.
EJU32811Launching the watercraft
When launching the watercraft, make sure
that there are no obstacles around you.
If there are waves, someone should make
sure that the watercraft is not pushed into the
trailer after launching the watercraft.

For VX Deluxe/VX Cruiser:
Use the remote control transmitter to select
the unlock mode. (See page 29 for Yamaha
Security System and low-RPM mode selec-
tion procedures.)
After the watercraft is in the water, start the
engine. Shift into reverse and move the wa-
tercraft back slowly.

For VX:
After the watercraft is in the water, turn it
around so that the bow faces the direction
you wish to go. Start the engine, and then
slowly move away from the launching area.
EJU32851Starting the engine
WARNING
EWJ00560
Never start the engine or let it run for any
length of time in an enclosed area. Ex-
haust fumes contain carbon monoxide, a

(4) Push the start switch (green button), and
then release it as soon as the engine
starts to run.
NOTE:
The engine will not start if the throttle lever is
squeezed.
CAUTION:
ECJ00480

Never push the start switch while the en-
gine 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. If the engine does not start
in 5 seconds, release the start switch,
wait 15 seconds, and then try again.
EJU32860Stopping the engine
To stop the engine, release the throttle lever,
and then push the engine stop switch (red
button).
WARNING
EWJ00600
You need throttle to steer. Shutting the en-
gine off can cause you to hit an obstacle
you are attempting to avoid. A collision
could result in severe injury or death.
EJU32890Leaving the watercraft
If leaving the watercraft, select the lock
mode of the Yamaha Security System (for
VX Deluxe/VX Cruiser) and remove the en-
gine shut-off cord to reduce the chance of
accidental starting or unauthorized use by
children or others. (See page 29 for
Yamaha Security System and low-RPM
mode selection procedures.)
