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.
Do not place magnets or objects with a
strong magnetic force near the throttle le-
ver or RiDE lever. The electronic throttle
mechanism of the levers can be adversely
affected, which could cause loss of control.
In addition, do not place objects suscepti-
ble to magnetic forces (i.e., credit cards,
watches, etc.) close to the throttle lever or
RiDE lever.
EJU42414
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 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 sharp-
ly if you apply throttle while turning the han-
dlebars.
The OTS system does not function below
planing speeds or when the engine is off.
Once the engine slows down, the water-
craft will no longer turn in response to han-
dlebar input until you apply throttle again or
you reach trolling speed.
Practice turning in an open area without
obstacles until you have a good feel for this
maneuver.
This watercraft is water-jet propelled. The
jet pump is directly connected to the en-
gine. This means that jet thrust will produce
some movement whenever the engine is
running and the “F” (forward) or “R” (re-
verse) shift indicator is displayed in the
multifunction display. When the “N” (neu-
tral) shift indicator is displayed, the forward
and reverse thrust are balanced to help
keep the watercraft from moving in either

Enjoy your watercraft
responsibly
You share the areas you enjoy when riding
your watercraft with others and with nature.
So your enjoyment includes a responsibility
to treat these other people, and the lands,
waters, and wildlife with respect and courte-
sy.
Whenever and wherever you ride, think of
yourself as the guest of those around you.
Remember, for example, that the sound of
your watercraft may be music to you, but it
could be just noise to others. And the exciting
splash of your wake can make waves others
won’t enjoy.
Avoid riding close to shoreline homes and
waterfowl nesting areas or other wildlife ar-
eas, and keep a respectful distance from fish-
ermen, other boats, swimmers, and
populated beaches. When travel in areas like
these is unavoidable, ride slowly and obey all
laws.
Proper maintenance is necessary to ensure
that the exhaust emission and sound levels of
your watercraft will continue to be within reg-
ulated limits. You have the responsibility to
make sure that the recommended mainte-
nance in this owner’s/operator’s manual is
carried out.
Remember, pollution can be harmful to the
environment. Do not refuel or add oil where a
spill could cause damage to nature. Remove
your watercraft from the water and move it
away from the shoreline before refueling. Dis-
pose of water and any fuel and oil residue in
the engine compartment according to local
regulations. And keep your surroundings
pleasant for the people and wildlife that share
the waterways: don’t litter.When you ride responsibly, with respect and
courtesy for others, you help ensure that our
waterways stay open for the enjoyment of a
variety of recreational opportunities.

Multifunction information
center
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.
If only the multifunction information center is
activated, the “WARNING” indicator light
blinks once.
TIP:
VX Deluxe / VX Cruiser: The “UNLOCK” indi-
cator light also comes on as part of the initial
operation.
The “UNLOCK” indicator light will go off
when the engine is started.
Multifunction information center standby
state
If the multifunction information center does
not receive any operation input within 25 sec-
onds after the engine stops, the center willturn 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.
EJU35026Information display
The information display shows watercraft op-
erating conditions.
EJU43830Speedometer
The speedometer shows the watercraft
speed against water.
By switching the display units, the speed can
be shown in kilometers per hour “km/h” or
miles per hour “MPH”.

If the fuel level warning is activated, refill the
fuel tank as soon as possible. (See page 51
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 53 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 overheatwarning 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 95 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.

EJU43731
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
the buzzer sounds intermittently for 30 sec-
onds.

Checking the engine oil level
WARNING
EWJ00341
Engine oil is extremely hot immediately af-
ter the engine is turned off. Coming in con-
tact with or getting any engine oil on your
clothes could result in burns.
NOTICE
ECJ00392
Do not run the engine with too much or
not enough oil in the oil tank, otherwise
the engine could be damaged.
Make sure that debris and water do not
enter the oil tank filler hole. Debris and
water in the engine oil can cause serious
engine damage.
TIP:
When checking the engine oil level on land,
the engine must be running while water is
being supplied to the cooling water pas-
sages. (See “Flushing the cooling water
passages” on page 81 for information on
supplying water.)
When checking the engine oil level on wa-
ter, moor the watercraft so that it will not
drift away.
