Emergency procedures EJU34631Cleaning the jet intake and impeller
WARNING
EWJ00780
Before attempting to remove weeds or de-
bris from the jet intake or impeller area,
shut the engine off and remove the clip
from the engine shut-off switch. Severe in-
jury or death could result from coming in
contact with the rotating parts of the jet
pump.
If weeds or debris gets caught in the jet intake
or impeller, cavitation can occur, causing jet
thrust to decrease even though engine speed
rises. If this condition is allowed to continue,
the engine will overheat and may seize.
NOTICE: If weeds or debris gets caught in
the jet intake, do not operate the watercraft
above trolling speed until they have been
removed.
[ECJ00651]
If there is any sign that the jet intake or impel-
ler is clogged with weeds or debris, return to
shore and check the intake and impeller. Al-ways stop the engine before beaching the wa-
tercraft.
(1) Place a suitable clean cloth or carpeting
underneath the watercraft to protect it
from abrasions and scratches. Turn the
watercraft on its side as shown. NOTICE:
Always turn the watercraft over onto
its port (left) side. When turning the
watercraft on its side, support the bow
so that the handlebars are not bent or
damaged.

(2) Remove any weeds or debris from
around the jet intake, drive shaft, impel-
ler, jet pump housing, and jet thrust noz-
zle.
If debris is difficult to remove, consult a
Yamaha dealer.
EJU34641Jumping the battery
If the watercraft battery has run down, the en-
gine can be started using a 12-volt booster
battery and jumper cables.
EJU34662Connecting the jumper cables
WARNING
EWJ01250
To avoid battery explosion and serious
damage to the electrical system:

Do not reverse the polarity of the jumper
cables when connecting to the batteries.

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.
(1) Connect the positive (+) jumper cable to
the positive (+) battery terminals of both
batteries.
(2) Connect one end of the negative (–)
jumper cable to the negative (–) battery
terminal of the booster battery.(3) Connect the other end of the negative (–)
jumper cable to an engine hanger.
(4) Start the engine, and then disconnect the
jumper cables by reversing the steps
above. NOTICE: 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 could
be damaged. If the engine does not
start in 5 seconds, release the start
switch, wait 15 seconds, and then try
again.

EJU34711Towing the watercraft
WARNING
EWJ00811

The operator of the towing boat must
keep speed to a minimum and avoid traf-
fic or obstacles which could be a hazard
to the operator on the watercraft.

The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down.
If the watercraft becomes inoperative in the
water, it can be towed to shore.
When the watercraft is towed using a towline,
the operator should hold onto the handlebars
and ride the watercraft in order to balance it.
Use a towline that is three times the combined
length of the towing boat and the watercraft.
Tow the watercraft at 5 mph (8 km/h) or less.
The bow must be kept up out of the water dur-
ing towing to prevent water from entering the
engine compartment.
EJU36151Submerged watercraft
If the watercraft is submerged or flooded with
water, follow the procedure below and consult
a Yamaha dealer as soon as possible. Failure
to do so could result in serious engine dam-
age.
(1) Beach the watercraft and remove the
stern drain plugs to drain the water fromthe engine compartment. (See page 54
for more information.)
Remove the storage compartment drain
plugs to drain the water from the storage
compartments.
(2) Install the stern drain plugs and storage
compartment drain plugs.
(3) Have the watercraft inspected by a
Yamaha dealer as soon as possible.
NOTICE: Be sure to have a Yamaha
dealer inspect the watercraft. Other-
wise, serious engine damage could re-
sult.
