Emergency procedures
EJU21602
Cleaning the jet intake and
impeller
If weeds or debris get caught in the 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. If there is any sign that the jet intake
or impeller is clogged with weeds or debris,
return to shore and check the intake and
impeller. Always stop the engine before
beaching the watercraft.
WARNING@ Before attempting to remove weeds or
debris from the jet intake or impeller
area, shut the engine off and remove the
clip from the engine shut-off switch.
Severe injury or death could result from
coming in contact with the rotating parts
of the jet pump.
@
CAUTION:@ If weeds or debris get caught in the
intake, do not operate the watercraft
above trolling speed until they have been
removed.
@
1. Turn the watercraft on its side as shown.

CAUTION:@ Place a suitable clean cloth or carpet-
ing underneath the watercraft to pro-
tect it from abrasions and scratches.
Always turn the watercraft over onto
its port (left) side.
When turning the watercraft on its
side, support the bow so the handle-
bars cannot be bent or damaged.
@
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 produce explosive gases. Keep
sparks, flame, cigarettes, etc. well away.
If using or charging the battery in an
enclosed space, make sure that it is well
ventilated. Always shield your eyes when
working near batteries.
KEEP OUT OF THE REACH OF CHIL-
DREN.

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 engine hanger 4.
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
then 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 3-9
for further instructions.) Remove the
storage compartment drain plugs to
drain the water from the storage com-
partments.
2. Install the stern drain plugs and storage
compartment drain plugs.
3. Disconnect the spark plug caps, and
then remove the spark plugs.
CAUTION:@ Do not connect the spark plugs to the
spark plug caps.
@
4. Disconnect the fuel injector couplers.
CAUTION:@ Cover the disconnected fuel injector cou-
plers so that they do not get wet. If the
couplers get wet, they could corrode,
which could lead to poor connections.
@
5. Crank the engine for 5 seconds at wide
open throttle. Repeat this step until all of
the water in the cylinders has been
expelled.
6. Spray a rust inhibitor into each spark
plug hole for 5 seconds.
7. Crank the engine for 5 seconds at wide
open throttle. Repeat this step several
times.

CAUTION:@ Do not start the engine even after com-
pleting the previous steps. Any water
remaining in the engine could cause seri-
ous engine damage.
@
8. Install the spark plugs, and then connect
the spark plug caps and fuel injector
couplers.
9. Have the watercraft inspected by a
Yamaha dealer as soon as possible.
CAUTION:@ Be sure to have a Yamaha dealer inspect
the watercraft. Otherwise, serious engine
damage could result.
