Watercraft characteristics

G
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.
G 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.
Keep away from the intake grate 1 while
G
the engine is on. Items such as long hair,
loose clothing, or PFD straps can become
entangled in moving parts resulting in
severe injury or drowning.
G Never insert any object into the jet thrust
nozzle 2 while the engine is running.
Severe injury or death could result from
coming in contact with the rotating parts
of the jet pump.
Stop the engine and remove the clip 3
G
from the engine shut-off switch 4 before
removing any debris or weeds, which may
have collected around the jet intake.
