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.
EJU30930
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.
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 ei-
ther “forward” or “reverse”, depending upon
the shift lever position (for VX Deluxe/VX
Cruiser).
For VX Deluxe/VX Cruiser:
Do not use the reverse function to slow
down or stop the watercraft as it could
cause you to lose control, be ejected, or im-
pact the handlebars.
This could increase the risk of back/spinal
injury (paralysis), facial injuries, and broken

To close the hood, push the hood down to
lock it in place.
NOTE:
Make sure that the hood is securely closed
before operating the watercraft.
EJU31090Fuel tank filler cap
To remove the fuel tank filler cap, turn it coun-
terclockwise.
NOTE:
Make sure that the fuel tank filler cap is se-
curely closed before operating the watercraft.
EJU31141Remote control transmitter (for VX
Deluxe/VX Cruiser)
The Yamaha Security System and low-RPM
mode settings are selected using the remote
control transmitter. (See “Yamaha Security
System and low-RPM mode” on page 32 forinformation on using the remote control trans-
mitter.)
CAUTION:
ECJ00020
The Yamaha Security System and low-
RPM mode settings can only be selected
using the remote control transmitter. Ob-
serve the following precautions to protect
your remote control transmitter:
Store the remote control transmitter
carefully so it will not be lost. When op-
erating the watercraft, use the transmit-
ter holder in the glove compartment. If
you accidentally lose your remote con-
trol transmitter, contact a Yamaha deal-
er.
While the remote control transmitter has
been designed for use in wet environ-
ments, it should not be operated under-
water or submerged for an extended
length of time. If it gets wet, dry it with a
soft, dry cloth.
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.
Use a soft, dry cloth to clean the trans-
mitter. Do not use detergent, alcohol, or
other chemicals.

Operation
52
(1) Launch the watercraft and start the en-
gine. (See page 52 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 32 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.
EJU32850Starting 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, acolorless, odorless gas that may cause
loss of consciousness and death within a
short time. Always operate the watercraft
in an open area.
(1) If the lock mode of the Yamaha Security
System is selected (for VX Deluxe/VX
Cruiser), use the remote control transmit-
ter to select the unlock mode. (See page
32 for Yamaha Security System and low-
RPM mode selection procedures.)
(2) Launch the watercraft in water free from
weeds and debris and at least 60 cm (2 ft)
deep.
WARNING
EWJ00570
Never operate in water that is less than 60
cm (2 ft) deep, otherwise you increase
your chance of hitting a submerged ob-
ject, which could result in injury.
CAUTION:
ECJ00470
Never operate in water that is less than 60
cm (2 ft) deep, otherwise pebbles or sand
could be sucked into the jet intake, caus-
ing impeller damage and engine overheat-
ing.

WARNING
EWJ00800
Do not use fuses of higher amperage than
recommended. Substitution with a fuse
that has an improper rating can cause ex-
tensive electrical system damage and pos-
sible fire.
EJU34710Towing the watercraft
If the watercraft becomes inoperative in the
water, it can be towed to shore.
If the watercraft must be towed in an emer-
gency using a towline, the operator should
ride the watercraft, holding onto the handle-
bars.
CAUTION:
ECJ00720
Tow the watercraft at 5 mph (8 km/h) or
less, otherwise water could enter the en-
gine through the exhaust passages or
through the air intake and flood the en-
gine compartment if it is towed too fast.
Tow the watercraft using the bow eye
only.
The bow must be kept up out of the wa-
ter during towing to prevent water from
entering the engine compartment.
WARNING
EWJ00810
The watercraft should only be towed in
an emergency.
The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down. A
good rule of thumb is a towline that is
three times the combined length of the
towing boat and the watercraft.
The operator of the towing boat must
keep speed to a minimum and avoid traf-
fic or obstacles which could be a hazard
to the rider on the watercraft.
EJU36150Submerged watercraft
If the watercraft is submerged or flooded with
water, follow the procedure below and consult
a Yamaha dealer as soon as possible. Failure
to do so could result in serious engine dam-
age!
In an emergency:
(1) Beach the watercraft and remove the
stern drain plugs to drain the water from
the engine compartment. (See page 46
for more information.) Remove the stor-
age compartment drain plugs to drain the
water from the storage compartments.
(2) Install the stern drain plugs and storage
compartment drain plugs.
(3) Disconnect the spark plug caps, and then
remove the spark plugs.
CAUTION:
ECJ00760
Do not connect the spark plugs to the
spark plug caps.
(4) Disconnect the fuel injector couplers.
CAUTION:
ECJ00770
Cover the disconnected fuel injector cou-
plers so that they do not get wet. If the cou-
