WARNING
EWJ00812
The operator of the towing boat must
keep speed to a minimum and avoid
traffic or obstacles which could be a
hazard to the operator on the water-
craft.
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. To tow the watercraft:
Use a towline that is three times the com-
bined length of the towing boat and the wa-
tercraft.
(1) Securely attach the towline to the bow
eye of the watercraft being towed.
(2) Sit astride the seat and hold on to the handlebars in order to balance the water-
craft. NOTICE: The bow must be kept
up out of the water during towing, oth-
erwise water could flood the engine
compartment or water could flow
back into the engine, causing severe
engine damage.
[ECJ01331]
Tow the watercraft at 8 km/h (5 mph) or less.
NOTICE: Tow the watercraft at 8 km/h (5
mph) or less, otherwise water could flood
the engine compartment or water could
flow back into the engine, causing severe
engine damage.
