Post-operation checks
Always perform the following post-opera-
tion checks after operating the watercraft.
1. Remove the watercraft from the water.
2. Wash down the hull, steering pole, han-
dlebars, and jet unit with fresh water.
3. Remove the hood and check the engine
compartment for water. To drain excess
water, turn the watercraft on its port (left)
side. If necessary, turn the watercraft
upside down to drain water completely.
CAUTION:@●Place a suitable clean cloth or carpet-
ing underneath the watercraft to pro-
tect it from abrasions and scratches.
●Always turn the watercraft over onto
its port (left) side.
●When turning the watercraft onto its
side or inverting it, support the bow
and secure the steering pole, other-
wise the steering pole and handlebars
could be bent or damaged.
@
NOTE:@This watercraft is equipped with an auto-
matic bilge-draining system that removes
water from the engine compartment while
you are underway. However, some residual
water will remain.
@
4. Put the watercraft in a horizontal posi-
tion.
5. Flush the cooling system to prevent it
from clogging with salt, sand, or dirt.
(See pages 4-1 to 4-2 for flushing the
cooling system procedures.)
6. Drain residual water from the exhaust
system by alternately squeezing and
releasing the throttle lever for 10 to
15 seconds while the engine is running.

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.
@
Transport this watercraft using the special
trailer that incorporates a hole into which the
pin 1 can be inserted and locked after
passing it through the rope hole 2.
After securing the bow with the pin, secure
the stern with ropes or tie downs 2 over the
gunwale. Use a rubber shock cord 1 to hold
the steering pole.
CAUTION:@●Do not route ropes or tie downs over
the steering pole, as they may damage
it. Also, wrap the ropes or tie downs
with towels or rags where they touch
the body of the watercraft to avoid
scratching or damage.
●Do not transport the watercraft with
steering pole up, or the steering pole
may be damaged during transporta-
tion.

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
by turning it counterclockwise.
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. 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. 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.
@
7. Lubricate the areas of the watercraft
specified under Lubrication points on
page 4-14.

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 with a new
gasket is a quarter turn to a half 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.

Lubrication points
To keep moving parts sliding or rotating
smoothly, coat them with water-resistant
grease.
●Throttle cable (carburetor end)
●Choke cable (carburetor end)
●Throttle cable (handlebar end)
Pull the throttle lever and remove the seal 1.
Spray a rust inhibitor into the outer cable. Refit
the seal securely.

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 the
battery electrolyte or charging the bat-
tery.
When checking the battery, make sure
the breather hose is connected to the
battery and not obstructed.

To replenish the battery:
1. Make sure the electrolyte level is between
the maximum 1 and minimum 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.
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.
@
To connect the battery terminals:
1. Make sure the connections are correct
when you insert the battery into the
watercraft.
2. Make sure that the breather hose is
properly connected and that it is not
damaged or obstructed.
3. Make sure the battery is securely held in
place.
