EJU34735Submerged watercraft
If the watercraft is submerged or flooded with
water, drain the bilge water from the engine
compartment. Then, have a Yamaha dealer
service the watercraft as soon as possible.
(1) Remove the watercraft from the water,
and then remove the hood.
(2) Turn the fuel cock knob to “OFF”.
(3) Turn the watercraft over far enough to
drain the bilge water from the engine
compartment. NOTICE: 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.
[ECJ00702]
(4) Turn the watercraft upright again.
(5) Have the watercraft serviced by a
Yamaha dealer as soon as possible.
NOTICE: Be sure to have a Yamaha
dealer inspect the watercraft. Other-
wise, serious engine damage could
result.
