drain plugs could be damaged, allow-
ing water to enter the engine compart-
ment. Check the O-rings on the stern
drain plugs and make sure that the
plugs are tightened securely before
launching the watercraft. Otherwise,
water may flood the engine compart-
ment and cause the watercraft to sub-
merge.
[ECJ00363]
(5) Securely install the stern drain plugs bytightening them until they stop.
EJU40535Draining the bilge water on water
A small quantity of bilge water will remain in
the engine compartment even after the bilge
water is drained on water. To completely
drain the bilge water, remove the watercraft
from the water and drain the bilge water on
land.
Jet vacuum bilge draining system
While the watercraft is operating, bilge water
in the engine compartment is drawn in by the
vacuum that is generated in the jet pump and
discharged from the watercraft through the
jet thrust nozzle.
To drain the bilge water on water:
Operate the watercraft as straight as possible
and above planing speed for at least 2 min-
utes. NOTICE: Do not run the engine at full
throttle for at least 1 minute after the en-
gine has been restarted. Bilge water in the engine compartment can splash into the
engine, which can result in severe dam-
age.

EJU42181Throttle lever checks
Operate the throttle lever several times to
make sure that operation is smooth through-
out the whole range. Also, make sure that the
throttle lever returns automatically to its fully
closed (idle) position when released.
EJU32664Engine shut-off cord (lanyard) check

them, and then make sure that the plugs and
O-rings on the plugs are not damaged and
that there is no foreign material on the
threads or O-rings on the plugs.
NOTICE:
Before installing the stern drain plugs,
clean the drain plug threads and the O-
rings on the plugs to remove any foreign
materials, such as dirt or sand. Otherwise,
the stern drain plugs could be damaged,
allowing water to enter the engine com-
partment. Check the O-rings on the stern
drain plugs and make sure that the plugs

(2) Pull yourself up to a kneeling position onthe boarding platform, and then move to
the seat and sit astride.
(3) Attach the engine shut-off cord (lanyard) to your left wrist, and then attach the clip
to the engine shut-off switch.
(4) Grip the handlebars with both hands and place both feet on the floor of the foot-
well.

EJU43260Boarding with passenger(s)EWJ01800
Severe internal injuries can occur if wa-
ter is forced into body cavities as a re-
sult of being near the jet thrust nozzle.
Do not start the engine until the passen-
gers are seated with their feet on the
floor of the footwell and are securely holding on to the person in front of them
or to the handgrip provided.
Before boarding the watercraft, make
sure that the engine is stopped. If the
engine is running, the reverse gate may
move down and a person boarding
could be pinched.
The heavier the total weight of the operator
and passenger(s), the more difficult it will be
to balance the watercraft. Do not operate the
watercraft when the total weight exceeds 225
kg (496 lb) including any cargo.
To board with passenger(s):
(1) Board as noted in the previous section
“Boarding alone”.
(2) Grip the handlebars with both hands and place both feet on the floor of the foot-
well.
(3) Have the first passenger move to the rear of the watercraft.

on the gunwale with your other hand or
your foot.
(3) Start the engine and operate the water- craft at planing speed to drain the bilge
water from the engine compartment.
(See page 46 for information on draining
the bilge water. If the engine does not
start, see “Towing the watercraft” on
page 87 or “Submerged watercraft” on
page 87.) NOTICE: Do not run the en-
gine at full throttle for at least 1 minute
after the engine has been restarted.
Bilge water in the engine compart-
ment can splash into the engine,
which can result in severe damage.
[ECJ00554]
EJU43282
Beaching and docking the watercraft
To beach the watercraft:
(1) Make sure that there are no boats, swim- mers, or obstacles near the beach. (2) Release the throttle lever to reduce
speed about 100 m (330 ft) before you
reach the intended beaching area.
(3) Slowly approach the beach using the throttle lever and RiDE lever to control
the watercraft speed. NOTICE: Never
run the engine in water that is less
than 60 cm (2 ft) deep from the bottom
of the watercraft, otherwise pebbles
or sand could be sucked into the jet
intake, causing impeller damage and
engine overheating.
[ECJ00473]
(4) After reaching land, stop the engine, and then get off the watercraft and pull it up
on the beach.
To dock the watercraft:
(1) Make sure that there are no boats, swim- mers, or obstacles near the dock.
(2) Release the throttle lever to reduce speed about 100 m (330 ft) away from
the dock.
(3) Slowly approach the dock using the throttle lever and RiDE lever to control
the watercraft speed.
(4) After coming alongside the dock, stop the engine, and then get off the water-
craft.
EJU37194Operating in weeded areas
Always avoid using your watercraft in areas
where weed growth is thick. If operating in
weeded areas is unavoidable, alternately
squeeze the throttle lever and relax your grip
on the throttle lever to vary the engine speed.
Weeds tend to become clogged more when
operating at a steady speed and at trolling
speed. If weeds may have clogged the intake
area, clean the jet intake. (See page 85 for in-
formation on the jet intake.)

Do not run the engine over 4000 r/min on
land. Also, do not run the engine for more
than 15 seconds without supplying water,
otherwise the engine could overheat.
After operating and removing the watercraft
from the water, promptly discharge the re-
maining water from the cooling water pas-
sages.
To discharge water from the cooling water
passages:
(1) Make sure that the area around the wa- tercraft is clear, and then start the en-
gine.
(2) Discharge the remaining water out of the cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(3) Stop the engine.

the cover.
TIP:
Make sure that the air filter case cover is se-
curely installed.
(6) Fasten the fuel hose to the holder usingthe plastic tie.
(7) Make sure that the area around the wa- tercraft is clear, and then start the engine
in a well-ventilated area and let it run at
idle for 15 seconds. (See page 24 for in-
formation on starting the engine.)

If debris is difficult to remove, consult a
Yamaha dealer.
EJU43472Raising the reverse gate
If the RiDE system malfunctions and the re-
verse gate remains in the lowered position,
the watercraft will not be able to move for-
ward.
After raising the reverse gate so that the wa-
tercraft can move forward, immediately re-
turn to shore and have a Yamaha dealer
service the watercraft.
To raise the reverse gate:
(1) Stop the engine and remove the clip from the engine shut-off switch.
(2) Enter the water and move to the rear of the watercraft.
(3) Slide the shift rod joint toward the bow, and then disconnect the shift rod joint
from the ball joint. (4) Raise the reverse gate to the forward po-
sition.TIP:
While the shift rod is disconnected, the re-
verse gate will not move to the neutral po-
sition or reverse position even if the RiDE
lever is squeezed.
If the RiDE lever is squeezed while the shift
rod is disconnected, the watercraft will
move forward.
EJU34642Jumping the battery
If the watercraft battery has run down, the en-
gine can be started using a 12-volt booster
battery and jumper cables.
EJU34664Connecting the jumper cablesEWJ01251
To avoid battery explosion and serious
damage to the electrical system:
Do not reverse the polarity of the jumper
cables when connecting to the batter-
ies.
Do not connect the negative (–) jumper
cable to the negative (–) terminal of the
watercraft battery.
Do not touch the positive (+) jumper ca-
ble to the negative (–) jumper cable.
