2007 YAMAHA SUPERJET engine

Trouble recovery
67

The bow must be kept up out of the wa-
ter during towing to prevent water from
entering the engine compartment.
WARNING
EWJ00810

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 traf-
fic or obstacles which could be a hazard
to the rider on the watercraft.
EJU34730Submerged watercraft
If the watercraft is submerged or flooded with
water, follow the procedure below and consult
a Yamaha dealer as soon as possible. Failure
to do so could result in serious engine dam-
age!
In an emergency:
(1) Beach the watercraft and remove the
hood. Turn the watercraft over far enough
to drain the water from the engine com-
partment.
CAUTION:
ECJ00700
Turning the watercraft on its side with the
hood removed could cause damage to the
steering pole. Use two people to provide
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 of the water in
the cylinders 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) Shut the engine off.
(10) Turn the fuel cock knob to “OFF”, remove
the silencer cap, and then spray a rust in-
hibitor into the carburetor while cranking
the engine.
(11) Have the watercraft inspected by a
Yamaha dealer as soon as possible.
