Stopping the watercraft
The watercraft is not equipped with a sep-
arate braking system. It is stopped by water
resistance when the throttle lever is
released. From full speed, the watercraft
comes to a complete stop in approximately
125 m (410 ft) after the throttle is released
and the engine is stopped, although this dis-
tance will vary depending on many factors,
including gross weight, water surface condi-
tions, and wind direction. The watercraft
slows down as soon as the throttle lever is
released, but will coast for a distance before
fully stopping. If you are not sure you can
stop in time before hitting an obstacle, apply
throttle and turn in another direction.
WARNING@ Allow adequate stopping distance.
Take early action to avoid collisions.
Remember, watercraft and other boats
do not have brakes.
Operate defensively at safe speeds
and keep a safe distance away from
people, objects, and other watercraft
to give you time to stop.
Do not shut the engine off when slow-
ing down in case you need engine
power to steer away from a boat or
other obstacle that comes into your
path.

Beaching the watercraft
1. Make sure no obstructions, boats or
swimmers are near the beach. Release
the throttle lever about 125 m (410 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.

EJU10820
Docking the watercraft
1. Make sure that no obstructions, boats or
swimmers are close to the watercraft.
Reduce speed about 125 m (410 ft)
away from the dock.
2. Slowly approach the dock and stop the
engine just before coming alongside it.
EJU10830
Rough water operation
The force of landing after jumping can
cause a strong impact on both the watercraft
and the operator and passenger. It is possi-
ble for the operator to hit his or her chest or
jaw on the watercraft body or handlebars
and be injured. Do not operate the water-
craft with your chin right above the handle-
bars or with your feet outside the watercraft.
Operating in rough water or jumping waves
can also crack the watercraft body or dam-
age internal parts. Avoid operating in rough
water or bad weather conditions.

Post-operation checks
WARNING@ Stay away from stern when engine is run-
ning on land. Hot water and steam spurt-
ing from exhaust outlet into the air can
cause serious burns.
@
Always perform the following post-opera-
tion checks after operating the watercraft.
1. Remove the watercraft from the water.
2. Wash down the hull, handlebars, and jet
unit with fresh water.
3. Remove the seat and check the engine
compartment for water. To drain excess
water, remove the stern drain plugs, and
then raise the bow of the watercraft
enough to allow water in the bilge to
drain out.
NOTE:@ This watercraft is equipped with a jet vac-
uum bilge draining system and an electric
bilge draining system that remove water
from the engine compartment while you are
underway. However, some residual water will
remain. (See “Bilge” on page 3-9 for more
information.)
@
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 page 4-1 for flushing procedures.)
6. Drain residual water from the exhaust sys-
tem by running the engine at 4,000 r/min
for 10 to 15 seconds.
CAUTION:@ Do not run engine over 4,000 r/min on
land. Otherwise catalytic converter could
sustain serious damage.

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 engine 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, handlebars, and jet unit
dry with a clean cloth.
11. Spray a rust inhibitor on metallic parts to
minimize corrosion.
WARNING@ Do not spray flammable rust inhibitor
products on engine surfaces while the
engine is hot. The sprayed substance or
propellants could catch fire.
@
12. Allow the engine compartment to air dry
completely before installing the seat.
NOTE:@ Cover watercraft after engine and catalytic
converter cool down.

Storage
WARNING@ Always place the watercraft upright in a
horizontal position when storing it, oth-
erwise fuel could leak out into the engine
or engine compartment, which could
result in 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.
EJU11941
Flushing the cooling system
Flushing the cooling system is essential
to prevent the cooling system from being
clogged with salt, sand, or dirt.
WARNING@ Stay away from stern when engine is run-
ning on land. Hot water and steam spurt-
ing from exhaust outlet into the air can
cause serious burns.
@
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 of the watercraft
for more than 15 seconds without sup-
plying water, otherwise the engine may
overheat.
Do not run engine over 4,000 r/min on
land. The catalytic converter could
sustain serious 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.

Lubrication
WARNING@ Do not spray flammable rust inhibitor
products on engine surfaces while the
engine is hot. The sprayed substance or
propellants could catch fire.
@
1. Remove the spark plugs and pour
approximately one tablespoon of oil into
each cylinder.
2. Grease the spark plug threads and rein-
stall the spark plugs.
3. Crank the engine within 3 seconds using
the start switch.
4. Lubricate all cables such as the throttle
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.
@
5. Lubricate the areas of the watercraft
specified under Lubrication points on
page 4-15.

NOTE:@ The condition of the battery can be known
by checking the specific gravity of the elec-
trolyte. However, you can also know the con-
dition of the battery by measuring the
voltage at both battery terminals. Charge
the battery if the voltage is less than
12 volts.
It is recommended to have a Yamaha dealer
check the specific gravity and to charge the
battery. If you maintain the battery yourself,
be sure to read and follow the instructions
provided with the battery tester and charger
you use.
