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.
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 such as Yamaha Stor-Rite
Engine Fogging Oil into the carburetor
while cranking the engine.
11. Have the watercraft inspected by a
Yamaha dealer as soon as possible.
