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 and supporting his body weight
on the riding tray. This will help keep the bow
of the watercraft out of the water.
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 rope
hole1 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 operator on the water-
craft.

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
hood. Turn the watercraft over far
enough to drain the water from the
engine compartment.
CAUTION:@ Turning the watercraft on its side with the
hood removed could cause damage to
the steering pole. Use two people to pro-
vide enough support to make sure that
the steering pole is not damaged.
@
2. Turn the watercraft upright again.
3. Turn the fuel cock knob to “OFF.”
4. Remove the spark plugs and dry them
with a cloth.
5. Without reinstalling the spark plugs,
crank the engine until all water in the cyl-
inders has been drained.
6. Install the spark plugs and the hood.
7. Turn the fuel cock knob to “ON.”
8. Launch the watercraft into the water, and
then run the engine for at least 10 min-
utes. If the engine does not start, repeat
steps 3–8.
9. Turn the engine off.
10. Turn the fuel cock knob to “OFF,” remove
the silencer cap, and then spray a rust
inhibitor into the carburetor while crank-
ing the engine.
11. Have the watercraft inspected by a
Yamaha dealer as soon as possible.
