Beaching the watercraft
1. Make sure no obstructions, boats or
swimmers are near the beach. Release
the throttle lever about 90 m (300 ft)
before you reach the intended beaching
area.
2. Approach the beach slowly and stop the
engine before reaching land.
Remember: you need throttle to steer.
3. Get off the watercraft and pull it up on
the beach.
CAUTION:@Small pebbles, sand, seaweed, and other
debris can be pulled into the jet intake
and impair or damage the impeller.
Always stop the engine and get off
before beaching the watercraft.

Rough water operation
The force of landing after jumping can
cause a strong impact on both the watercraft
and the operator. It is possible for the opera-
tor to hit his or her chest or jaw on the water-
craft body or handlebars and be injured. Do
not operate the watercraft with your chin
right above the handlebars or with your feet
outside the watercraft. Operating in rough
water or jumping waves can also crack the
watercraft body or damage internal parts.
Avoid operating in rough water or bad
weather conditions.

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.

CAUTION:@Do not run the engine at full throttle or
for more than 15 seconds on land, other-
wise the engine may overheat and seize.
@
7. If the watercraft will be stored for a week
or more, lubricate internal engine com-
ponents to help prevent corrosion. (See
page 4-3 for lubrication procedures.)
8. Rinse the engine and engine compart-
ment with a small amount of water.
CAUTION:@Do not use high pressure when rinsing
the engine or engine compartment as
severe damage could result.
@
9. Wipe the engine and engine compart-
ment dry with a clean cloth (repeat
step 3, if necessary).
10. Wipe the hull, steering pole, handlebars,
and jet unit dry with a clean cloth.
11. Spray a rust inhibitor on metallic parts to
minimize corrosion.
12. Allow the engine compartment to air dry
completely before reinstalling the hood.

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.

Storage
WARNING@Always place the fuel cock knob in the
“OFF” position when storing the water-
craft. Otherwise, fuel could leak out into
the engine or engine compartment,
which would create a fire hazard.
@
Storage for prolonged periods of time,
such as winter storage, requires preventa-
tive maintenance to ensure against deterio-
ration. It is advisable to have the watercraft
serviced by a Yamaha dealer prior to stor-
age. However, the following procedures can
be performed by the owner.
EJU00517
Flushing the cooling system
Flushing the cooling system is essential
to prevent the cooling system from clogging
up with salt, sand, or dirt.
Yamaha recommends using the optional
flush kit to make flushing easier.
See the instructions included with the
flush kit for proper installation.
CAUTION:@●Do not supply water to the cooling
water passages when the engine is not
running. The water could flow back
through the muffler into the crankcase
causing severe engine damage.
●Do not run the engine for more than
15 seconds without supplying water,
otherwise the engine may overheat.

1. Put the watercraft on land in a horizontal
position.
2. Insert the garden hose adapter 2 into
the flush hose connector 1.
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
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 of the cooling
water passages by alternately squeezing
and releasing the throttle lever for 10 to
15 seconds.
7. Stop the engine.
8. Remove the garden hose adapter.
NOTE:
If you use the flushing attachment 4 in the
tool kit, remove the plug 3 and install the
attachment.
Then, follow steps 3 to 8 above.

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.
