2. Remove any weeds or debris from
around the drive shaft, impeller, pump
housing, and jet thrust nozzle.
If debris is difficult to remove, consult
your Yamaha dealer.
CAUTION:
Always avoid operating your watercraft in
areas where weed growth is thick. If trav-
eling in weeded areas is unavoidable,
operate the engine alternately at partial
throttle and full throttle. Weeds tend to
accumulate more at a steady speed and
at trolling speed. If weeds clog the intake
or impeller area and cause cavitation, fol-
low the cleaning procedure above.

Jumping the battery
If the watercraft battery has run down, the
engine can be started using a 12-volt bat-
tery and jumper cables.
WARNING
Battery electrolyte is poisonous and dan-
gerous, causing severe burns, etc. Elec-
trolyte contains sulfuric acid. Avoid
contact with skin, eyes or clothing.
Antidotes
External: Flush with water.
Internal: Drink large quantities of water
or milk. Follow with milk of magnesia,
beaten egg or vegetable oil. Call physi-
cian immediately.
Eyes: Flush with water for 15 minutes
and get prompt medical attention.
Batteries give off explosive gases. Keep
sparks, flame, cigarettes, etc. well away.
If using or charging the battery in an
enclosed area, make sure that it is well
ventilated. Always shield your eyes when
working near batteries.
KEEP OUT OF THE REACH OF CHILDREN.

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 tow line, the operator
should ride the watercraft, holding onto the
handlebars.
CAUTION:
●Tow the watercraft slowly; water may
enter the air intake and flood the
engine compartment if the watercraft
is towed too fast.
●Tow the watercraft using the bow eye 1
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 tow line 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 tow line which
is three times the combined length of
the towing boat and the watercraft. A
shorter length of rope can be used if
the watercraft is towed very slowly.
●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!
1. Beach the watercraft and remove the
stern drain plugs to drain the water from
the engine compartment.
2. Turn the fuel cock knob to “OFF.”
3. Remove the spark plugs and dry them
with a cloth.
4. Without reinstalling the spark plugs,
crank the engine until all the water in the
cylinders has been drained.
5. Install the stern drain plugs and the
spark plugs.
6. Turn the fuel cock to “ON.”
7. Launch the watercraft into the water, and
then run the engine for at least
10 minutes. If the engine will not start,
repeat steps above.
8. Turn the engine off. Turn the fuel cock to
“OFF.”
9. Remove the silencer caps and spray a
rust inhibitor into the carburetor while
cranking the engine.
10. Have the watercraft inspected by a
Yamaha dealer as soon as possible.
