WARNING@
Do not release the throttle lever when
trying to steer away from objects—you
need throttle to steer. A collision could
result in severe injury or death.

When operating at higher speeds,
make gradual turns or slow down
before turning. Sharp high-speed turns
may cause the watercraft to slide side-
ways or spin, throwing the operator
and passengers overboard which
could cause an injury.
@
This model has the Yamaha Engine Man-
agement System (YEMS) that includes an
Off-Throttle Steering (OTS) system. It will
activate at planing speeds should you
attempt to steer the watercraft after releas-
ing the throttle lever (see condition C
above). 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.

5. Start the engine in a well-ventilated area
and let it run at idle for 15 seconds.
CAUTION:@ Do not run the engine for more than
15 seconds. The engine could overheat.

Inspecting the jet thrust nozzle
angle
Check for smooth operation of the handle-
bars and jet thrust nozzle.
Turn the handlebars as far as possible to
the right and left and check that the differ-
ence of distances A and B between the jet
thrust nozzle and the nozzle is within specifi-
cation.
If steering is stiff or misadjusted, have a
Yamaha dealer service it.

Inspecting the shift cable
(for VX110 Deluxe)
Place the shift lever in the reverse posi-
tion.
Make sure that the reverse gate makes
contact with the stopper 1.
If the reverse gate does not make contact
with the stopper, have a Yamaha dealer ser-
vice it. Difference of A and B:
Maximum 5 mm (0.20 in)
