1. Put the watercraft on land in a horizontal
position.
2. Open the flushing hose connector cap 1,
and then inser t the garden hose adapter 
2
into the flushing hose connector 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.
7. Stop the engine.
8. Remove the garden hose adapter and
secure the cap.

Lubrication
WARNING
To reduce the risk of fire or explosion:
Never pour or spray gasoline, or any sub-
stance other than engine fogging oil
through the holes in the carburetor
silencer cover.
CAUTION:
●Be sure to replace the caps 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 caps 1 on the
silencer by turning them counterclock-
wise.
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 fogging oil as pos-
sible through the holes in the silencer
cover. Keep spraying until the engine
stalls (or a maximum of 15 seconds). 
4. Install the cap securely.
5. Remove the spark plugs and pour
approximately one tablespoon of engine
oil into each cylinder. Grease the spark
plug threads and install the spark plugs.
6. Crank the engine for 3 seconds.
7. Lubricate all cables such as the throttle,
choke, and steering cables.
8. Lubricate the areas of the watercraft
specified under Lubrication points on
page 4-15.

Inspecting the battery
Check the level of the battery electrolyte
and make sure the leads are secure.
WARNING
Battery electrolyte is poisonous and dan-
gerous, causing severe burns, etc. Elec-
trolyte contains sulfuric acid. Avoid
contact with skin, eyes or clothing.
Antidotes
External: Flush with water. 
Internal: Drink large quantities of water
or milk. Follow with milk of magnesia,
beaten egg or vegetable oil. Call physi-
cian 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 battery in an
enclosed space, make sure that it is well
ventilated. Always shield your eyes when
working near batteries.
KEEP OUT OF THE REACH OF CHIL-
DREN.
CAUTION:
Be careful not to place the battery on its
side.
Make sure to remove the battery from the
battery compartment when adding bat-
tery electrolyte or charging the battery.
When checking the battery, make sure
the breather hose is connected to the
battery and not obstructed.

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 charge the battery:
1. Remove the caps from the battery cells.
If the level is low, add distilled water if
necessary.
2. Connect the battery to a charger. Set the
charging rate at 1.9 A, and then charge
the battery for 10 hours.
WARNING
●The battery gives off explosive gases.
When charging the battery, keep it well
away from sparks and open flames.
●When using a battery charger, connect
the battery to the charger before you
turn the charger on. This will prevent
sparking at the terminals, which could
ignite battery gases.
Specific gravity: 1.28 at 20 °C (68 °F)
To connect the battery terminals:
1. Make sure that the connections are correct
when you insert 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.
