Connecting the jumper cables 
1. Connect the positive (+) jumper cable 1
to the positive (+) terminals of both bat-
teries. 
2. Connect one end of the negative (–)
jumper cable 2 to the negative (–) termi-
nal of the booster battery 3. 
3. Connect the other end of the negative (–)
cable to an unpainted bolt on the cylinder
head.
CAUTION:@ Do not connect the end of the jumper
cable to the negative (–) terminal on the
watercraft battery! Be sure all connec-
tions are secure and correct before
attempting to start the engine. Any
wrong connection may damage the elec-
trical system. 
@
4. Start the engine, and then disconnect
the cables by reversing the steps above.
CAUTION:@ 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 may be damaged. If the engine
does not start in 5 seconds, release
the start switch, wait 15 seconds, and
try again.

Towing the watercraft 
If the watercraft becomes inoperative in
the water, it can be towed to shore. 
If the watercraft must be towed in an
emergency using a towline, the operator
should ride the watercraft, holding onto the
handlebars.
CAUTION:@ Tow the watercraft at 5 mph (8 km/h) or
less, otherwise water could enter the
engine through the exhaust passages
or through the air intake and flood the
engine compartment if it is towed too
fast. 
Tow the watercraft using the bow
eye1 only. 
The bow must be kept up out of the
water during towing to prevent water
from entering the engine compart-
ment. 
@
WARNING@ The watercraft should only be towed in
an emergency. 
The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down. A
good rule of thumb is a towline that is
three times the combined length of the
towing boat and the watercraft. 
The operator of the towing boat must
keep speed to a minimum and avoid
traffic or obstacles which could be a
hazard to the rider on the watercraft.

Submerged watercraft 
If the watercraft is submerged or flooded
with water, follow the procedure below and
consult a Yamaha dealer as soon as possi-
ble. Failure to do so may result in serious
engine damage!
In an emergency: 
1. Beach the watercraft and remove the
stern drain plugs to drain the water from
the engine compartment. (See page 3-8
for further instructions.) 
Remove the storage compartment plugs
to drain the water from each storage
compartment. 
2. Install the stern drain plugs. 
3. Have the watercraft inspected by a
Yamaha dealer as soon as possible.
