Safety information

watch the skier’s hand signals and condi-
tion.
FX High Output
FX Cruiser 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
34
The bow eye is used to attach a rope to the
watercraft when transporting, mooring, or
towing it in an emergency.
EJU34880Stern eyes
The stern eyes are located at the stern of the
watercraft.
The stern eyes are used to attach a rope to
the watercraft when transporting or mooring it.
EJU34891Pull-up cleats
(for FX Cruiser High Output)
The pull-up cleats are used to attach a rope to
the watercraft when mooring it.
To use a pull-up cleat, pull it up. WARNING!
Do not use the pull-up cleats to lift the wa-
tercraft. The pull-up cleats are not de-
signed to support the watercraft’s weight.
If the pull-up cleats break, the watercraftcould fall, which could result in severe in-
jury.

Yamaha Engine Management System
(YEMS)
This model is equipped with an integrated,
computerized management system that con-
trols and adjusts ignition timing, fuel injection,
engine diagnostics, and the off-throttle steer-
ing (OTS) system.
EJU31381Yamaha Security System
The Yamaha Security System functions to
help prevent unauthorized use or theft of the
watercraft. The engine cannot be started if the
security system is in the lock mode. The en-
gine can only be started in the unlock mode.
The lock and unlock modes of the security
system are selected using the remote control
transmitter that is included with this water-
craft.
TIP:
Since the watercraft is programmed to recog-
nize the internal code from this transmitter
only, the security system setting can only be
changed with this transmitter. If you lose the
remote control transmitter or if it does not op-
erate properly, contact a Yamaha dealer.

which can result in severe damage.
[ECJ00541]
(3) Start the engine and operate the water-
craft as straight as possible and above
planing speed for at least 2 minutes to
discharge any water remaining in the en-
gine compartment. (If the engine does
not start, see “Towing the watercraft” on
page 95 or “Submerged watercraft” on
page 95.) NOTICE: Do not operate the
engine at full throttle for at least 1
minute after the engine has been re-
started. Excessive water in the engine
compartment can splash into the en-
gine, which can result in severe dam-
age.

EJU33251
Turning the watercraft
WARNING
EWJ00770
Do not release the throttle lever when
trying to steer away from objects—youneed throttle to steer. A collision could
result in severe injury or death.
When operating at higher speeds, make
gradual turns or slow down before turn-
ing. Sharp high-speed turns may cause
the watercraft to slide sideways or spin,
throwing the operator and passengers
overboard, which could cause an injury.
Steering control depends on the combination
of handlebar position and the amount of throt-
tle.
Water sucked in through the intake grate is
pressurized by the impeller in the jet pump. As
the pressurized water is expelled from the
pump through the jet thrust nozzle, it creates
thrust to move and steer the watercraft. The
higher the engine speed, the more thrust pro-
duced.
The amount of jet thrust, in addition to the po-
sition of the handlebars, determines how
sharply you turn.
A. More throttle produces higher thrust, so
the watercraft will turn more sharply.

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 54
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.
