nozzle moves as the handlebars are turned,
and that there is no difference between the
right and left fully turned positions of the jet
thrust nozzle.

Operator riding position
The operator should grip the handlebars firm-
ly with both hands and sit astride the seat
with both feet on the floor of the footwell.
Passenger riding position
The passenger(s) should hold on firmly, either
to the person in front of them or to the hand-
grip provided, and sit astride the seat with

not push the watercraft into the trailer.
EJU46251Starting the engine on waterEWJ01532
Do not apply throttle when anyone is at the
rear of the watercraft. Turn the engine off
or keep it at idle. Water and debris exiting
the jet thrust nozzle can cause severe in-
jury.
To start the engine:
(1) VX DELUXE / VX CRUISER / VXLIMITED: If the lock mode is selected forthe Yamaha Security System setting, se-
lect the unlock mode. (See page 25 for
Yamaha Security System setting proce- dures.)
(2) Move the watercraft to an area that is free from weeds and debris, and has a
water depth of at least 60 cm (2 ft) from
the bottom of the watercraft. NOTICE:
Never run the engine in water that is
less than 60 cm (2 ft) deep from the
bottom of the watercraft, otherwise
pebbles or sand could be sucked into
the jet intake, causing impeller dam-
age and engine overheating.
[ECJ00473]
(3) Attach the engine shut-off cord (lanyard) to your left wrist, and then attach the clip
to the engine shut-off switch. (See page
26 for information on operating the en-
gine shut-off switch.) WARNING! Check

that the engine shut-off cord (lanyard)
is attached correctly. If the engine
shut-off cord (lanyard) is not attached
correctly, it may not pull free when the
operator falls off, allowing the water-
craft to continue to run and cause an
accident.

(2) Release the throttle lever to reduce speed about 70 m (230 ft) before you
reach the intended beaching area.
(3) Slowly approach the beach using the throttle lever and RiDE lever to control
the watercraft speed. NOTICE: Never
run the engine in water that is less
than 60 cm (2 ft) deep from the bottom
of the watercraft, otherwise pebbles
or sand could be sucked into the jet

craft.
EJU37194Operating in weeded areas
Always avoid using your watercraft in areas
where weed growth is thick. If operating in
weeded areas is unavoidable, alternately
squeeze the throttle lever and relax your grip
on the throttle lever to vary the engine speed.
Weeds tend to become clogged more when
operating at a steady speed and at trolling
speed. If weeds may have clogged the intake
area, clean the jet intake. (See page 106 for
information on the jet intake.)
