battery and jumper cables.
EJU34652Connecting 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 unpainted bolt on the
cylinder head.
(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.

system damage and possible fire.

Towing 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 ride the watercraft, hold-
ing onto the handlebars and supporting his or
her body weight on the riding tray. This will
help keep the bow of the watercraft out of the
water.
Use a towline that is three times the combined
length of the towing boat and the watercraft.Tow the watercraft using the bow rope hole
only.
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.
EJU34731Submerged 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
hood.
(2) Turn the fuel cock knob to “OFF”.
(3) Turn the watercraft over far enough to
drain the water from the engine compart-
ment. NOTICE: Turning the watercraft
on its side with the hood removed
could cause damage to the steering
pole. Use two people to provide
enough support to make sure that the
steering pole is not damaged.
[ECJ00701]
(4) Turn the watercraft upright again.
(5) 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.
