Safety information
18
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.

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.
