Cruising limitations
Scan constantly for people, objects, and
other watercraft. Be alert for conditions
that limit your visibility or block your vision
of others.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft.
Do not follow directly behind watercraft or
other boats.
Do not go near others to spray or splash
them with water.
Avoid sharp turns or other maneuvers that
make it hard for others to avoid you or un-
derstand where you are going.
Avoid areas with submerged objects or
shallow water.
Take early action to avoid collisions. Re-
member, watercraft and other boats do not
have brakes.
Do not release the throttle lever when trying
to steer away from objects—you need
throttle to steer. Always check throttle and
steering controls before starting the water-
craft.
Ride within your limits and avoid aggres-
sive maneuvers to reduce the risk of loss of
control, ejection, and collision.
This is a high performance boat—not a toy.
Sharp turns or jumping wakes or waves
can increase the risk of back/spinal injury(paralysis), facial injuries, and broken legs,
ankles, and other bones. Do not jump
wakes or waves.
Do not operate the watercraft in rough wa-
ter, bad weather, or when visibility is poor;
this may lead to an accident causing injury
or death. Be alert to the possibility of ad-
verse weather. Take note of weather fore-
casts and the prevailing weather
conditions before setting out on your wa-
tercraft.
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
60 cm (2 ft)

Voltmeter
The voltmeter shows the battery voltage.
When the battery voltage is normal, the volt-
meter displays approximately 12 volts.
If the battery voltage has dropped significant-
ly, “LO” is displayed on the voltmeter. If the
battery voltage has risen significantly, “HI” is
displayed. If “LO” or “HI” is displayed, imme-
diately return to shore and have a Yamaha
dealer service the watercraft.
To switch to the voltmeter from the hour me-
ter:
Push the select button for at least 1 second
after the multifunction information center is
activated for more than 10 seconds. The dis-
play switches to the voltmeter from the hour
meter.
EJU31515Fuel 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 eight display
segments, which disappear two 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.
EJU41973Fuel level warning
If the fuel remaining in the fuel tank drops to
about 11 L (2.9 US gal, 2.4 Imp.gal), the low-
est two fuel level segments, the fuel level
warning indicator, and the “WARNING” indi-
cator light blink, and the buzzer sounds inter-
mittently.
If the fuel level warning is activated, refill the
fuel tank as soon as possible. (See page 40
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.

gine overheat warning indicator and the
“WARNING” indicator light stop blinking and
remain on, and the buzzer sounds continu-ously. At the same time, 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 82 for information on the jet intake.)

Operation and handling requirements
41
(6) Stop filling when the fuel level reaches
approximately 50 mm (2 in) from the top
of the fuel tank. Do not overfill the fuel
tank. Because fuel expands when it
heats up, heat from the engine or the sun
can cause fuel to spill out of the fuel tank.Do not leave the watercraft with a full
tank in direct sunlight.
(7) Wipe up any spilled fuel immediately with
a dry cloth.
(8) Securely install the fuel filler cap by tight-
ening it until it clicks.
(9) Securely install the seat in its original po-
sition. Fuel tank capacity:
70 L (18.5 US gal, 15.4 Imp.gal)

Operating your watercraft
WARNING
EWJ00511
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.
EJU32965Getting to know your watercraft
Operating your watercraft requires skills ac-
quired through practice over a period of time.
Take the time to learn the basic techniques
well before attempting more difficult maneu-
vers.
Operating your new watercraft can be a very
enjoyable activity, providing you with hours of
pleasure. However, it is essential to familiar-
ize yourself with the operation of the water-
craft to achieve the skill level necessary to
enjoy riding safely.
Before operating this watercraft, read this
owner’s/operator’s manual, the Riding Prac-
tice Guide, the Riding Instruction card, and all
labels on the watercraft. Pay particular atten-
tion to the safety information beginning on
page 10. These materials should give you an
understanding of the watercraft and its oper-
ation.
Remember: This watercraft is designed to
carry the operator and up to 2 passengers.
Never exceed the maximum load limit or al-
low more than 3 persons (or 2 persons if a
wakeboarder or water-skier is being pulled)
to ride the watercraft at any time.
EJU33006Learning to operate your watercraft
Before operating the watercraft, always per-
form the pre-operation checks listed on page
47. The short time spent checking the water-
craft will reward you with added safety and
reliability.
Check local laws before operating your wa-
tercraft.
Operate defensively at safe speeds and keep
a safe distance away from people, objects,
and other watercraft. Select a wide area to
learn in, where there is good visibility and
light boat traffic.
Use the buddy system—operate with some-
one nearby. Scan constantly for people, ob-
jects, and other watercraft. Be alert for
conditions that limit your visibility or block
your vision of others.
You should grip the handlebars firmly and
keep both feet on the floor of the footwell. Do
not attempt to ride with passengers until your
operating skills are fully developed.Maximum load:
240 kg (530 lb)
Load is the total weight of cargo, op-
erator, and passengers.
