EJU34711Towing the watercraft
WARNING
EWJ00811
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 operator on the watercraft.
The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down.
If the watercraft becomes inoperative in the
water, it can be towed to shore.
When the watercraft is towed using a towline,
the operator should hold onto the handlebars
and ride the watercraft in order to balance it.
Use a towline that is three times the combined
length of the towing boat and the watercraft.
Tow the watercraft at 5 mph (8 km/h) or less.
The bow must be kept up out of the water dur-
ing towing to prevent water from entering the
engine compartment.
EJU36151Submerged 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.
(1) Beach the watercraft and remove the
stern drain plugs to drain the water fromthe engine compartment. (See page 47
for more information.)
Remove the storage compartment drain
plugs to drain the water from the storage
compartments.
(2) Install the stern drain plugs and storage
compartment drain plugs.
(3) Have the watercraft inspected 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 re-
sult.
