Safety information
12
As with any water sport, you should not op-
erate your watercraft without someone else
nearby. If you operate further than swim-
ming distance from shore, you should be
accompanied by another boat or water-
craft, but make sure you stay a safe dis-
tance away. It’s good, common sense.
Never operate in water that is less than 60
cm (2 ft) deep from the bottom of the wa-
tercraft, otherwise you increase your
chance of hitting a submerged object,
which could result in injury.
This watercraft is not equipped with light-
ing required for night operation. Do not op-
erate the watercraft after sunset or before
dawn, otherwise you increase the risk of
colliding with another boat, which could re-
sult in severe injury or death.
Follow navigation rules, and state/provin-
cial and local laws that apply to watercraft.
EJU43131
Operation requirements
All riders must wear a personal flotation de-
vice (PFD) that is approved by the appro-
priate authorities and is suitable for
personal watercraft use.
Wear protective clothing. Severe internal
injuries can occur if water is forced into
body cavities as a result of falling into the
water or being near the jet thrust nozzle.
You must wear shorts with neoprene (wet-
suit material) to keep water from being
forcefully injected into the rectum or vagina
during a fall backward. Riders not wearing
neoprene shorts have received severe rec-
tal, vaginal, and internal injuries resulting in
permanent damage. Normal swimwear
does not offer adequate protection.
Eye protection is recommended to keep
wind, water, and glare from the sun out of
your eyes while you operate your water-
craft. Restraining straps for eyewear are
made which are designed to float should
your eyewear fall in the water.
Footwear and gloves are recommended.
You must decide whether to wear a helmet
while you ride for recreation. You should
know that a helmet could help protect you

Watercraft glossary
Trolling speed
“Trolling” is the lowest maneuvering speed. You are applying little or no throttle. The water-
craft is down in the water, and there is no wake.
Sub-planing speed
“Sub-planing” is a medium speed. The bow of the watercraft is slightly up from the water sur-
face, but you are still traveling through the water. There is a wake.
Planing speed
“Planing” is a faster speed. The watercraft is more level and is skimming on top of the water.
There is a wake.
Bow
The front end of the watercraft.
Stern
The rear end of the watercraft.
Starboard
The right side of the watercraft when facing forward.
Port
The left side of the watercraft when facing forward.
Bilge water
Water that has collected in the engine compartment.
Yamaha Engine Management System (YEMS) YEMS is an integrated, computerized management system that controls and adjusts ignition
timing, fuel injection, engine diagnostics, and the off-throttle steering (OTS) system.
Reverse with Intuitive Deceleration Electronics (RiDE)
RiDE is an electronic system that controls the reverse, neutral, and deceleration operations of
the watercraft.

EJU45891Reverse assist
The reverse assist is a function for temporar-
ily increasing the engine speed when moving
in reverse, such as to enter the water
smoothly when launching the watercraft from
a trailer.
This function operates after the engine is
started and only if the watercraft is not shifted
into forward.
TIP:
Once the watercraft is shifted into forward af-
ter the engine is started, the reverse assist
cannot be operated.
Activating and deactivating the reverse
assist
The activation of the reverse assist can be
confirmed by the reverse assist indicator on
the multifunction information center.
To activate the reverse assist:
(1) Start the engine.
(2) Squeeze the RiDE lever to the fully open
position, and then push the upper side of
the “SPEED ADJUST” switch. Once the

JUST” switch when the reverse assist level
is set to +1.
Squeeze the throttle lever.EJU46280T.D.E. (thrust directional enhancer)
The T.D.E. is a function for slightly lifting or
lowering the reverse gate from the neutral po-
sition to operate the watercraft at very low speeds when the engine is running at idling
speed.
This function can be used only when the wa-
tercraft is in neutral.
Activating and deactivating the T.D.E.
The activation of the T.D.E. can be confirmed
by the T.D.E. indicator on the multifunction
information center.
To activate the T.D.E.:
(1) Shift into neutral.
(2) Push the upper side of the “T.D.E.”
switch to move forward at a very low
speed or push the lower side of the
“T.D.E.” switch to move in reverse at a
very low speed.

Multifunction information center (VX-C / VX)
The multifunction information center displays
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.
Multifunction information center standby
state
If the multifunction information center does
not receive any operation input within 30 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.
EJU35027Information display
The information display shows watercraft op-
erating conditions.
EJU46430Speedometer
The speedometer shows the watercraft
speed.
By switching the display units, the speed can
be shown in kilometers per hour “km/h” or
miles per hour “MPH”.
TIP:
“MPH” is selected as the display unit at the
Yamaha factory.

and have a Yamaha dealer service the water-
craft.
EJU37272Fuel level meter
The fuel level meter shows the amount of fuel
remaining in the fuel tank. The amount of re-
maining fuel is shown using four display seg-
ments, which disappear one at a time as the
fuel level decreases.
TIP:
The accuracy of the fuel level meter varies
depending on the operating conditions. Use
this function as a reference only.
EJU44711Fuel level warning
If the fuel remaining in the fuel tank drops to
about 18 L (4.8 US gal, 4.0 Imp.gal), the low-
est fuel level segment, the fuel level warning
indicator, and the “WARNING” indicator lightblink, and the buzzer sounds intermittently for
30 seconds.
If the fuel level warning is activated, refill the
fuel tank as soon as possible. (See page 62
for information on filling the fuel tank.)
After the fuel tank is refilled, the warning sig-
nals will be cleared when the engine is re-
started.
EJU43720Oil pressure warning
If the oil pressure drops significantly, the oil
pressure warning indicator, the check engine
warning indicator, and the “WARNING” indi-
cator light blink, and the buzzer sounds inter-
mittently for 30 seconds. At the same time,
the maximum engine speed is limited.
If the oil pressure warning is activated, imme-
diately reduce the engine speed, return to
shore, and then check the engine oil level.
(See page 64 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.

EJU43901Engine overheat warning
If the engine temperature rises significantly,
the engine overheat warning indicator, the
check engine warning indicator, and the
“WARNING” indicator light blink, and the
buzzer sounds intermittently. After 5 sec-
onds, the engine overheat warning indicator
and the “WARNING” indicator light stop
blinking and remain on, and the buzzer
sounds continuously. After 30 seconds, the
buzzer stops. While the engine overheat
warning is activated, the maximum engine
speed is limited.
If the engine overheat warning is activated,
immediately reduce the engine speed, return
to shore, and then make sure that water is
being discharged from the cooling water pilot
outlet while the engine is running. If there is
no discharge of water, stop the engine, and
then check the jet intake for clogging. (See
page 107 for information on the jet intake.)
NOTICE: If you cannot locate and correct
the cause of the overheating, consult a
Yamaha dealer. Continuing to operate at higher speeds could result in severe en-
gine damage. [ECJ00042]

Check engine warning
If a sensor malfunction or a short circuit is de-
tected, the check engine warning indicator
and the “WARNING” indicator light blink, and

onds.
If the engine is stopped after the check en-
gine warning is activated, the tachometer
portion of the information display will show
