Safety information
18
watch the skier’s hand signals and condi-
tion.
FX High Output

Your control while pulling a water-skier is
affected by the skier’s ability, as well as wa-
ter and weather conditions.

When preparing to pull a skier, operate the
watercraft at the slowest possible speeduntil the watercraft is well away from the ski-
er and slack in the ski rope is taken up.
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, ap-
ply enough throttle to raise the skier.

Make smooth, wide turns. The watercraft is
capable of very sharp turns, which could ex-
ceed the abilities of the skier. Keep the skier
at least 50 m (150 ft), about twice the dis-
tance of a standard ski rope, from any po-
tential 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, op-
erate slowly and cautiously.

Features and functions
32
ahead acceleration when on plane and top
speed are enhanced.
In some conditions, however, the watercraft
may tend to “porpoise” (hop in the water). If
the watercraft is porpoising, select neutral or
bow down.
EJU31360Handgrip
The handgrip provides a handhold for board-
ing the watercraft and for a spotter when fac-
ing rearward.

WARNING
EWJ00020
Do not use the handgrip to lift the water-
craft. The watercraft could fall, which
could result in severe injury.
EJU34860Reboarding step
The reboarding step provides a handhold and
footstep for boarding the watercraft.
CAUTION:
ECJ00740
Use the reboarding step only to board the
watercraft in the water. Do not use the re-
boarding step for lifting the watercraft, as
a footstep when the watercraft is on land,
or for any other purpose. The watercraft
can be damaged.
EJU34870Bow eye
The bow eye is located at the bow of the wa-
tercraft.
The bow eye is used to attach a rope to the
watercraft when transporting, mooring, or
towing it in an emergency.

Trouble recovery
97
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 isthree 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 54
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.
