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.

Fire extinguisher
Check that there is a full fire extinguisher
on board. The fire extinguisher container 1
is located on the underside of the rear seat.
(See page 2-4 for rear seat removal proce-
dures.)
To open the fire extinguisher container
cap 2, turn it counterclockwise.
After inserting the fire extinguisher, make
sure that the container cap is tightened
securely.
Install the fire extinguisher container on
the seat and secure it with the bands 3.
NOTE:@
See the instructions supplied by the fire
extinguisher manufacturer for checking
the fire extinguisher. Always keep the
extinguisher in the fire extinguisher con-
tainer.

Always carry a fire extinguisher on board.
A fire extinguisher is not standard equip-
ment with this watercraft. If you do not
have one, contact a Yamaha dealer or a
fire extinguisher dealer to obtain one
meeting the proper specifications.

Operation
WARNING@ Before operating your watercraft,
become familiar with all controls. Con-
sult your Yamaha dealer about any con-
trol or function you do not fully
understand. Failure to understand how
controls work could cause an accident or
prevent you from avoiding an accident.
@
CAUTION:@ Make sure that the stern drain plugs are
securely tightened before launching the
watercraft.

Engine break-in
The engine break-in period is essential to
allow the various components of the engine
to wear and polish themselves to the correct
operating clearances. This ensures proper
performance and promotes longer compo-
nent life.
CAUTION:@
For the first tankful of operation, pre-
mix a 50:1 mixture of fuel and oil (in
addition to the oil in the oil tank).

After break-in, use straight gasoline
for normal operation.
@
1. Launch the watercraft and start the
engine. (See page 3-15 for engine start-
ing procedures.)
2. Run the engine at the lowest possible
speed for 5 minutes.

Boarding with passengers
WARNING@ Severe internal injuries can occur if
water is forced into body cavities as a
result of being near the jet thrust nozzle.
Do not apply throttle until each passen-
ger is seated with his or her feet on the
floor of the footwell and is holding on to
the person in front of him or her.
@
1. Climb on board as noted in the previous
section, and sit astride the seat. Attach
the engine shut-off cord to your left wrist,
and then install the clip to the engine
shut-off switch.
2. Have the passenger move to the rear of
the watercraft.
3. Have the passenger get on board and sit
on the seat. If a second passenger is
getting on, have him or her follow the
same procedure.
NOTE:@ When a passenger is getting on board, both
he and the operator should try to balance
the watercraft.
@
4. The operator should check to see that
the passengers have their feet on the
floor of the footwell and that they are
securely holding on to the person in front
of them.
5. Start the engine, look in all directions,
and then accelerate to planing speed.
WARNING@ Before starting off, make sure that there
are no boats, obstructions, or swimmers
around you.

Transporting
WARNING@ Always place the fuel cock knob in the
“OFF” position when transporting the
watercraft, otherwise fuel could leak out
into the engine or engine compartment,
which would create a fire hazard.
@
When transporting the watercraft on a
trailer, secure the tie downs to the trailer
through the bow eye and stern rope holes.
CAUTION:@ Do not route ropes or tie downs over the
seat, as they may leave permanent marks
on the seat’s surface. Also, wrap the
ropes or tie downs with towels or rags
where they touch the body of the water-
craft to avoid scratching or damage.

1. Put the watercraft on land in a horizontal
position.
2. Open the flushing hose connector
cap1, and then insert the garden hose
adapter 2 into the flushing hose con-
nector 3 and turn it until it is securely
connected.
3. Connect the garden hose adapter to a
water tap using a hose.
4. Start the engine, and then immediately
turn the water supply on until water flows
out continually from the cooling water
pilot outlet.
5. Run the engine at idling speed for about
3 minutes watching the engine condition.
If the engine stops while flushing, turn
the water supply off immediately and
repeat the above steps.
6. Turn the water supply off, and then force
the remaining water out from the cooling
passages by alternately squeezing, and
releasing the throttle lever for 10 to
15 seconds.

Lubrication
WARNING@ To reduce the risk of fire or explosion:
Never pour or spray gasoline, or any sub-
stance other than a rust inhibitor through
the hole in the carburetor silencer cover.
@
CAUTION:@
Make sure to replace the cap securely
after fogging the engine, otherwise
water could enter the engine and
cause damage.

Do not attempt to run the engine at full
throttle or for more than 15 seconds
while the watercraft is out of the water,
otherwise the engine may overheat
and/or seize.
@
1. Open the silencer cap 1 on the silencer.
2. Start the engine with the watercraft in a
well-ventilated area.
3. With the engine running at a fast idle,
quickly spray as much rust inhibitor as
possible through the hole in the silencer
cover. Keep spraying until the engine
stalls (or a maximum of 15 seconds).
4. Install the cap securely.
5. Lubricate all cables such as the throttle,
choke, and steering cables.
NOTE:@ Use a suitable marine grease applicator to
pressure lubricate the cables and purge out
any moisture between the inner and outer
cables.
@
6. Lubricate the areas of the watercraft
specified under Lubrication points on
page 4-15.

Fuel system
Draining the fuel system prevents buildup
of varnishes and other harmful deposits that
result when gasoline sits for a prolonged
period of time.
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.

If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.

Inspecting the battery
Check the level of the battery electrolyte
and make sure that the negative and posi-
tive leads are securely tightened.
WARNING@
Battery electrolyte is poisonous and
dangerous, causing severe burns, etc.
Electrolyte contains sulfuric acid.
Avoid contact with skin, eyes, or cloth-
ing.
Antidotes
External: Flush with water.
Internal: Drink large quantities of water
or milk. Follow with milk of magnesia,
beaten egg, or vegetable oil. Call phy-
sician immediately.
Eyes: Flush with water for 15 minutes
and get prompt medical attention.
Batteries produce explosive gases.
Keep sparks, flame, cigarettes, etc.,
well away. If using or charging the bat-
tery in an enclosed space, make sure
that it is well ventilated. Always shield
your eyes when working near batter-
ies.
KEEP OUT OF THE REACH OF CHIL-
DREN.

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.
@
CAUTION:@
Be careful not to place the battery on
its side.

Be sure to remove the battery from the
battery compartment when adding
electrolyte or charging the battery.
