This watercraft is not equipped with light-
ing required for night operation. Do not
operate the watercraft after sunset or
before dawn, otherwise you increase the
risk of colliding with another boat, which
could result in severe injury or death.
EJU10020
Operation requirements
All riders must wear an authority-
approved PFD that 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
water or being near the jet thrust nozzle.
Normal swimwear does not adequately
protect against forceful water entry into
rectum or vagina. All riders must wear a
wetsuit bottom or clothing that provides
equivalent protection. Such clothing
includes thick, tightly woven, sturdy and
snug-fitting apparel such as denim, but
does not include spandex or similar fab-
rics, like those used in bicycle shorts.

Authority-approved PFD

Wetsuit bottom
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.

Engine overheat warning
system
This model is equipped with an engine
overheat warning system.
If the engine starts to overheat, the warn-
ing light and the engine overheat warning
indicator begin to blink, and the buzzer
sounds intermittently.
When this occurs, reduce the engine
speed and beach the watercraft. Check for
water discharge. If there is no discharge of
water at the cooling water pilot outlet, whole
the engine is running, check the intake grate
and impeller for clogging.
WARNING@ Before attempting to remove weeds or
debris from the intake grate or impeller,
shut the engine off and remove the clip
from the engine shut-off switch. Severe
injury or death could result from coming
in contact with the rotating parts of the
jet pump.
@
CAUTION:@ This watercraft is equipped with a cata-
lytic converter.
Return to shore at low speed if over-
heat warning indicator and buzzer
come on. If you ignore these signals,
engine will stop running and cannot be
restarted until exhaust system cools
down.
Have your watercraft inspected and
serviced by a Yamaha dealer if engine
stops due to overheating.

If the overheat warning is ignored, engine
and exhaust system heat may increase, par-
ticularly if the watercraft is operated at
higher speeds. When this occurs, the warn-
ing light, the engine overheat warning indi-
cator and the buzzer will change from
intermittently to continuously on, and the
overheat system will stop ignition to the
engine to reduce the risk of severe over-
heating. The engine cannot be started until
it cools down, so it may be necessary to
have the watercraft towed back to the
beach. (See “Towing the watercraft” on page
5-7 for towing procedures.)
NOTE:@ Press the select button on the multifunction
information center to stop the buzzer.

Exhaust temperature warning
system
This model is equipped with an exhaust
temperature warning system.
If the exhaust temperature gets too hot,
the warning light and exhaust temperature
warning indicator begin to blink, and the
buzzer sounds intermittently.
When this occurs, reduce engine speed
and beach the watercraft to allow the
exhaust system to cool down.
WARNING@ Hot muffler surfaces can cause serious
burns. Do not touch any muffler surface
during or after engine operation. The cat-
alytic converter gets hotter after the
engine stops.

@
Hour meter
The hour meter is provided to make it
easy to follow the maintenance schedule.
The meter shows the hours of engine
operation that have elapsed since the water-
craft was new.
Vo l t m e t e r
The voltmeter is provided to display the
voltage of the battery.
The voltmeter displays 12 volts or more
when the battery voltage is within specifica-
tion.
If the voltage displayed is low, beach the
watercraft and, if necessary, have a Yamaha
dealer check the charging system.

Fuel warning indicator
If the fuel remaining in the tank drops to
about 13 L (3.4 US gal, 2.9 Imp gal), the
lowest two fuel level segments, the fuel
warning indicator and the warning light
begin to blink. The buzzer also starts sound-
ing intermittently.
The warning signals will be cleared when
the engine restarts after refilling fuel.

cator and the warning light begin to blink.
The buzzer also starts sounding intermit-
tently.
If the oil warning indicators begin to blink,
refill with engine oil as soon as possible.
The warning signals will be cleared when
the engine restarts after refilling engine oil.
NOTE:@ If the warning indicators blink with adequate
oil in the tank, have a Yamaha dealer check
the oil filter for dirt and clogs.

warning system” on page 2-12 for further
details.)
The warning signals will turn off when the
engine is started after it has cooled down.
NOTE:@ When the warnings overlap each other, their
priority is as follows:
1. Final overheat warning
2. Fuel level warning
3. Oil level warning
4. Initial overheat warning
5. Exhaust temperature warning
6. Check engine warning

Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level just reaches the
bottom of the filler tube. Do not fill up
the filler tube because fuel expands as
it warms up and could overflow. If tem-
porarily leaving the watercraft with a
full fuel tank, do not leave it in direct
sunlight. Leave it in a well-ventilated
area with the watercraft in a horizontal
position.
Tighten the filler cap securely after
refueling.
If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.
If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.
@
CAUTION:@ Do not use leaded gasoline. Leaded
gasoline can seriously damage the
catalytic converter.
Use only fresh gasoline that has been
stored in clean containers.
@
Recommended gasoline:
Regular unleaded gasoline with
a minimum octane rating of
86 (Pump octane number) = (R+M)/2
90 (Research octane number)
