WARNING
EWJ00800
Do not use fuses of higher amperage than
recommended. Substitution with a fuse
that has an improper rating can cause ex-
tensive electrical system damage and pos-
sible fire.
EJU34710Towing the watercraft
If the watercraft becomes inoperative in the
water, it can be towed to shore.
If the watercraft must be towed in an emer-
gency using a towline, the operator should
ride the watercraft, holding onto the handle-
bars.
CAUTION:
ECJ00720

Tow the watercraft at 5 mph (8 km/h) or
less, otherwise water could enter the en-
gine through the exhaust passages or
through the air intake and flood the en-
gine compartment if it is towed too fast.

Tow the watercraft using the bow eye
only.

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.
EJU36150Submerged 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
stern drain plugs to drain the water from
the engine compartment. (See page 46
for more information.) Remove the stor-
age compartment drain plugs to drain the
water from the storage compartments.
(2) Install the stern drain plugs and storage
compartment drain plugs.
(3) Disconnect the spark plug caps, and then
remove the spark plugs.
CAUTION:
ECJ00760
Do not connect the spark plugs to the
spark plug caps.
(4) Disconnect the fuel injector couplers.
CAUTION:
ECJ00770
Cover the disconnected fuel injector cou-
plers so that they do not get wet. If the cou-

plers 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 ex-
pelled.
(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.
(8) Install the spark plugs, and then connect
the spark plug caps and fuel injector cou-
plers.
CAUTION:
ECJ00780
Do not start the engine even after complet-
ing the previous steps. Any water remain-
ing in the engine could cause serious
engine damage.
(9) Have the watercraft inspected by a
Yamaha dealer as soon as possible.
CAUTION:
ECJ00790
Be sure to have a Yamaha dealer inspect
the watercraft. Otherwise, serious engine
damage could result.
