Hazard information
● Never start the engine or let it run for any
length of time in an enclosed area.
Exhaust fumes contain carbon monoxide,
a colorless, odorless gas that may cause
loss of consciousness and death within a
short time. Always operate the watercraft
in an open area.
●
Hot oil tank, muffler, and engine surfaces
can cause serious burns. Do not touch
the oil tank, muffler, or engine immedi-
ately after turning the engine off.

Watercraft characteristics
● Jet thrust turns the watercraft. Releasing
the throttle lever completely produces
only minimum thrust. If you are traveling
at speeds above trolling, you will have
rapidly decreasing ability to steer without
throttle. This model has the Yamaha
Engine Management System (YEMS)
that includes an Off-Throttle Steering
(OTS) system. It will activate at planing
speeds should you attempt to steer the
watercraft after releasing the throttle lever.
The OTS system assists in turning by
continuing to supply some thrust while the
watercraft is decelerating, but you can
turn more sharply if you apply throttle
while turning the handlebars. The OTS
system does not function below planing
speeds or when the engine is off. Once
the engine slows down, the watercraft will
no longer turn in response to handlebar
input until you apply throttle again or you
reach trolling speed. Practice turning in
an open area without obstructions until
you have a good feel for this maneuver.
● This watercraft is water-jet propelled. The
jet pump is directly connected to the
engine. This means that jet thrust will pro-
duce some movement whenever the
engine is running. There is no “neutral”
position. You are in either “forward” or
“reverse,” depending upon the shift lever
position.
● Do not use the reverse function to slow
down or stop the watercraft as it could
cause you to lose control, be ejected, or
impact the handlebars. You could also
damage the shift mechanism.
This could increase the risk of back/spinal
injury (paralysis), facial injuries, and bro-
ken legs, ankles, and other bones.
