Fuel meter
The fuel meter is provided for convenient
fuel level checking while riding. The fuel
meter has eight segments which show the
amount of fuel remaining in the fuel tank.
NOTE:@ The indication of the segments differs on
your operating condition. Use the meter as a
reference.

EJU01032
Hour meter
The hour meter is provided to make it
easy to follow the maintenance schedule.
The meter shows the hours of engine opera-
tion that have elapsed since the watercraft
was new.
NOTE:@
The elapsed time will be kept even if the
battery terminals have been discon-
nected.

If the hour meter malfunctions, “_ _ _ _”
display and the warning light will blink.

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.
EJU01034
Oil warning indicator
If the oil remaining in the tank drops to
about 1.7 L (0.45 US gal, 0.37 Imp gal) or
the oil filter is clogged, the oil warning indi-
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, check the oil filter for clog-
ging.

Engine overheat warning
indicator
If the engine starts to overheat, the warn-
ing light and engine overheat warning indi-
cator begin to blink, and the buzzer sounds
intermittently.
If the watercraft continues to be operated
at higher speeds after the warning system
has been activated, the warning light,
engine overheat warning indicator and the
buzzer will change from intermittently to
continuously on. (See “Engine overheat
warning system” on page 2-13 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

Fuel and oil
This engine uses Yamaha’s oil injection
system, which provides superior lubrication
by ensuring the proper oil ratio for all operat-
ing conditions. No fuel premixing is neces-
sary except during the engine break-in
period. Simply pour gasoline into the fuel
tank and oil into the oil tank.
EJU01911
Gasoline
WARNING@ GASOLINE AND ITS VAPORS ARE
HIGHLY FLAMMABLE AND EXPLOSIVE!

Do not smoke when refueling, and
keep away from sparks, flames, or
other sources of ignition.

Stop engine before refueling.

Refuel in a well-ventilated area with
the watercraft in a horizontal position.

Do not stand or sit on the watercraft
while refueling in case of fire.

Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.

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.

Filling the oil tank
WARNING@
Do not add gasoline to the oil tank.
Fire or explosion could result.

Oil in the bilge is a serious fire hazard.
Wipe up any spilled oil immediately.
@
CAUTION:@ Do not allow the oil tank to become com-
pletely empty. If the oil tank becomes
empty the oil injection pump must be
bled to ensure proper oil flow, otherwise
engine damage may occur. If bleeding of
the oil pump is necessary, have a
Yamaha dealer bleed it.
@
1. Remove the seat to watch the oil level.
(See page 2-5 for seat.)
2. Open the oil tank filler cap, and very
slowly add engine oil to the oil tank.
3. Stop filling when the oil just reaches the
top of oil tank visible.
Oil tank capacity:
5.5 L (1.5 US gal, 1.2 Imp gal)

Pre-operation checks
EJU01347
Pre-operation check list
Before operating this watercraft, perform the checks in the following check list. See the
accompanying text in this chapter for details on how to perform the checks.
WARNING@ If any item in the pre-operation check list is not working properly, have it inspected
and repaired before operating the watercraft, otherwise an accident could occur.
@
POC-***
NOTE:@ Pre-operation checks should be made thoroughly each time the watercraft is used. This pro-
cedure can be completed in a short time. It is worth the time spent to assure safety and reli-
ability.

Pre-operation check points
EJU01050
Engine compartment
Ventilate the engine compar tment before
each use.
To ventilate the engine compartment,
remove seat and front storage compart-
ment. (See page 2-5 for seat, and 2-20 for
front storage compartment.) Allow the
engine compartment to remain open for a
few minutes to allow any fuel vapors to
escape. Also, check for loose electrical con-
nections.
WARNING@ Failure to ventilate the engine compart-
ment could result in fire or explosion. Do
not start the engine if there is a fuel leak
or a loose electrical connection.
@
EJU01051
Fuel and oil systems
Check the fuel system for leakage, cracks
or malfunctions before each use. (See page
4-9 for check points and correct proce-
dures.)
1. Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.
2. Remove seat and front storage compart-
ment. (See page 2-5 for seat, and 2-20
for front storage compartment.)
3. Check the fuel and oil levels in the tanks
and replenish if necessary. (See pages
3-3 and 3-4 for filling instructions.)
4. Turn the fuel cock to the “ON” position.

Battery
Check the battery condition and the elec-
trolyte level.
Check that the battery leads are tightened
securely and there is no corrosion on the
battery terminals.
WARNING@
The battery must always be fully
charged and in good condition. Loss
of battery power may leave you
stranded. Never operate the watercraft
if the battery does not have sufficient
power to start the engine or if it shows
any other signs of decreased power.

Be sure to connect the breather hose
to the battery. Fire or explosion could
result if the breather hose is damaged,
obstructed, or not connected properly.
@
Make sure that the battery is securely
held in place.

Throttle
Squeeze and release the throttle lever
several times to make sure that there is no
hesitation in its travel. It should be smooth
over the complete range, and spring back to
the idle position when released.
WARNING@ Before starting the engine, always check
the operation of the throttle lever.
@
EJU01057
Steering system
Check for looseness in the handlebars.
Turn them as far as possible to the right
and left to make sure that operation is
smooth and unrestricted throughout the
whole range. Make sure that the jet thrust
nozzle also changes directions as the han-
dlebars are turned, and that there is no free
play between the handlebars and the jet
thrust nozzle.

EJU01058
Jet unit
Carefully check the jet intake for weeds,
debris, or anything else that might restrict
the intake of water. If the intake is clogged,
cavitation could occur, reducing jet thrust,
and possibly damaging the jet pump.
In some cases, the engine may overheat
because of lack of cooling water, and dam-
age to the engine could result. Engine cool-
ing water is fed to the engine by the jet
pump. (See page 5-4 for jet intake cleaning
procedures.)
WARNING@
Keep away from intake grate while
engine is on. Items such as long hair,
loose clothing, or PFD straps can
become entangled in moving parts
resulting in severe injury or drowning.

Stop the engine and remove the clip
from the engine shut-off switch before
removing any debris or weeds, which
may have collected around the jet
intake.

EJU01059
Engine shut-off cord (lanyard)
Check that the engine shut-off cord is not
frayed or broken. If the cord is damaged,
replace it; never try to repair it or tie it
together.
