EJU44730Engine 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 port (left) cooling
water pilot outlet while the engine is running.
If there is no discharge of water, stop the en-
gine, and then check the jet intake for clog-
ging. (See page 92 for information on the jet
intake.) NOTICE: If you cannot locate and
correct the cause of the overheating, con-
sult a Yamaha dealer. Continuing to oper-ate at higher speeds could result in severe
engine damage. [ECJ00042]
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.
If the engine is stopped after the check en-
gine warning is activated, the information dis-
play will indicate an error code.
If the check engine warning is activated, im-
mediately reduce the engine speed, return to
shore, and have a Yamaha dealer check the
engine.

The elapsed time will be kept even if the bat-
tery terminals have been disconnected.
EJU43751Voltmeter
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, and the
information display, hour meter, and indicator
lights turn off. If the battery voltage has risen
significantly, “HI” is displayed. If “Lo” or “HI”
is displayed, immediately return to shore and
have a Yamaha dealer service the watercraft.

(4) Pull the hood latch up, and then lift up
the rear of the hood.
(5) Loosen the fuel filler cap and remove it.
(6) Slowly add fuel to the fuel tank.
(7) Stop filling when the fuel level reaches
approximately 50 mm (2 in) from the topof 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.
(8) Wipe up any spilled fuel immediately with
a dry cloth.
(9) Securely install the fuel filler cap by tight-
ening it until it clicks.
(10) Return the hood to its original position,
and then push the hood latch down to
securely lock it in place. Make sure that
the fuel filler cap and the hood are se-

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
56. 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.

proximately 120 m (390 ft) after the throttle le-
ver is released or the engine is stopped,
although this distance will vary depending on
many factors, including gross weight, water
surface conditions, and wind direction.
If the RiDE lever is squeezed to slow down,
the stopping distance is approximately 30%
shorter than when the RiDE lever is not used.
However, this distance will vary depending
on many factors, including gross weight, wa-
ter surface conditions, and wind direction.
WARNING
EWJ01791
Allow adequate stopping distance.
Take early action to avoid collisions. Re-
member, watercraft and other boats do
not have brakes.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft to give you
time to stop.
Do not shut the engine off when slowing
down in case you need engine power to
steer away from a boat or other obstacle
that comes into your path.
To avoid rear-end collisions while oper-
ating the watercraft, check behind you
before using the RiDE lever to slow
down or stop the watercraft.
EJU43442Operating the watercraft in reverse or
neutral
Operating in reverse
When the RiDE lever is squeezed, the “R” (re-
verse) shift indicator will be displayed in the
multifunction display and the watercraft will
move in reverse. (See page 31 for shift sys-
tem operation procedures.)
Make sure that there are no obstacles or peo-
ple behind you before shifting into reverse.
TIP:
This model is equipped with a function which
limits the engine speed in reverse.
Operating in neutral
When the RiDE lever is squeezed lightly and
released, the “N” (neutral) shift indicator will
be displayed in the multifunction display and
the watercraft will stop in its current location.
