Safety information

Make sure that the rope is not looped
around anything.
After checking that the skier is ready and
that there is no traffic or other obstacles,
apply enough throttle to raise the skier.
Make smooth, wide turns. The watercraft is
capable of very sharp turns, which could
exceed the abilities of the skier. Keep the
skier at least 50 m (164 ft), about twice the
distance of a standard ski rope, from any
potential hazard.
Be alert to the hazard of the ski rope handle
snapping back at the watercraft when the
skier falls or is unable to get up on the skis.
Towing heavy or bulky objects other than
skiers, such as another boat or watercraft,
can cause loss of steering control and cre-
ate a hazardous condition. If you must tow
another boat in an emergency situation,
operate slowly and cautiously.
EJU30971
Safe boating rules
Your Yamaha watercraft is legally considered
a powerboat. Operation of the watercraft
must be in accordance with the rules and
regulations governing the waterway on which
it is used.

reboarding step to lift the watercraft. The
reboarding step is not designed to support
the watercraft’s weight. If the reboarding
step breaks, the watercraft could fall,
which could result in severe injury.
[EWJ01212]
NOTICE
ECJ00743
Use the reboarding step only to board the
watercraft in the water. Do not use the re-
boarding step for any other purpose. The
watercraft can be damaged.
EJU34873Bow eye
The bow eye is used to attach a rope to the
watercraft when transporting, mooring, or
towing it in an emergency. (See page 98 for
information on towing the watercraft.)
EJU34882Stern eyes
The stern eyes are used to attach a rope to
the watercraft when transporting or mooring
it.
EJU40421Cleat
The cleat is used to attach a ski rope to the
watercraft when pulling a water-skier.
WARNING! Do not use the cleat to lift the watercraft. The cleat is not designed to
support the watercraft’s weight. If the

Operation
77
To upright the watercraft:
(1) Remove the clip from the engine shut-offswitch.
(2) Swim to the rear of the watercraft. Turn the watercraft over clockwise by pulling
on the ride plate with your left hand while
pushing down on the gunwale with your
right hand or foot.
If the port (left) side of the capsized wa-
tercraft is tilting up, push down on the
gunwale so that the port (left) side is
down before turning the watercraft
clockwise. NOTICE: Do not turn the
watercraft over counterclockwise,
otherwise water can enter the engine,
which can result in severe damage.
[ECJ00542]
(3) Start the engine and operate the water- craft at planing speed to drain the bilge
water from the engine compartment.
(See page 52 for information on draining the bilge water. If the engine does not
start, see “Towing the watercraft” on
page 98 or “Submerged watercraft” on
page 99.) NOTICE:
Do not run the en-
gine at full throttle for at least 1 minute
after the engine has been restarted.
Bilge water in the engine compart-
ment can splash into the engine,
which can result in severe damage.
[ECJ00554]

Beaching and docking the watercraft
To beach the watercraft:
(1) Make sure that there are no boats, swim- mers, or obstacles near the beach.
(2) Release the throttle lever to reduce speed about 125 m (410 ft) before you
reach the intended beaching area.
(3) Slowly approach the beach and stop the engine just before reaching land.
WARNING! You need throttle to steer. Shutting the engine off can cause you
to hit an obstacle you are attempting
to avoid. A collision could result in se-
vere injury or death.
[EWJ00602] NOTICE:
Never run the engine in water that is
less than 60 cm (2 ft) deep from the
bottom of the watercraft, otherwise
pebbles or sand could be sucked into
the jet intake, causing impeller dam-
age and engine overheating.
[ECJ00473]

To dock the watercraft:
(1) Make sure that there are no boats, swim- mers, or obstacles near the dock.
(2) Release the throttle lever to reduce speed about 125 m (410 ft) away from
the dock.
(3) Slowly approach the dock and stop the engine just before coming alongside it.
WARNING! You need throttle to steer.

cap. (See page 95 for information on the fuse
puller.)
(5) Securely install the fuse cover, and thenfit the bilge pump fuse holder into the
rubber cover.
(6) Secure the bilge pump fuse leads and corrugated tube with the plastic ties.
(7) Securely install the engine cover and seats in their original positions. If the fuse immediately blows again, the elec-
trical system may be defective. If this occurs,
have a Yamaha dealer service the watercraft.
EJU34716Towing the watercraft
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
