Transporting
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 running the engine at
4,000 r/min or less within 10 to 15 sec-
onds.
7. Stop the engine.
8. Remove the garden hose adapter and
secure the cap.

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.

Fill the fuel tank with fresh gasoline and
add 470 ml (15.9 US oz, 16.5 Imp oz) of
Yamaha Fuel Stabilizer and Conditioner.
CAUTION:Use only Yamaha Fuel Stabilizer and
Conditioner. Using another stabilizer can
damage the catalytic converter.

Recommended fuel stabilizer:
Yamaha Fuel Stabilizer and
Conditioner

NOTE:@
Wipe off any water on the spark plug or
inside the cap before installing the spark
plug cap. Push the spark plug cap down
until it clicks.

If a torque wrench is not available when
you are fitting a new spark plug, a good
estimate of the correct torque is 1/4 turn
to 1/2 turn past finger tight. Have the
spark plug adjusted to the correct torque
with a torque wrench as soon as possible.
@
WARNING@ Be careful not to damage the insulator
when removing or installing a spark plug.
A damaged insulator could allow sparks
to escape, which could lead to explosion
or fire.

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.

To replenish the battery:
1. Make sure that the electrolyte level is
between the upper 1 and lower 2 level
marks.
2. Refill the battery with distilled water if
necessary.
CAUTION:@ Normal tap water contains minerals that
are harmful to a battery. Use only dis-
tilled water for replenishing the battery.
@
To recharge the battery:
CAUTION:@ Do not attempt to charge a battery hast-
ily. Battery life could be shortened.
@
It is recommended to have a Yamaha
dealer charge the battery. If you charge the
battery yourself, carefully read the battery
charger instructions before charging and fol-
low the points below.
1. Remove all caps from the battery cell.
2. Add distilled water to the specified level if
the electrolyte level is low.
3. Set the charging rate to 1.9 ampere and
charge the battery slowly until the explo-
sive gases are discharged vigorously
from the battery cells.
To connect the battery terminals:
1. Make sure that the connections are cor-
rect when you install the battery in the
watercraft.
2. Make sure that the breather hose is
properly connected and that it is not
damaged or obstructed.
3. Make sure that the battery is securely
held in place.

Connecting the jumper cables
1. Connect the positive (+) jumper cable 1
to the positive (+) terminals of both bat-
teries.
2. Connect one end of the negative (–)
jumper cable 2 to the negative (–) termi-
nal of the booster battery 3.
3. Connect the other end of the negative (–)
cable to an unpainted bolt on the cylinder
head.
CAUTION:@ Do not connect the end of the jumper
cable to the negative (–) terminal on the
watercraft battery! Be sure all connec-
tions are secure and correct before
attempting to start the engine. Any
wrong connection may damage the elec-
trical system.
@
4. Start the engine, and then disconnect
the cables by reversing the steps above.
CAUTION:@
Never push the start switch while the
engine is running.

Do not operate the start switch for
more than 5 seconds, otherwise the
battery will be discharged and the
engine will not start. Also, the starter
motor may be damaged. If the engine
does not start in 5 seconds, release
the start switch, wait 15 seconds, and
try again.
