Safety information
15
EX SPORT: Do not use the reverse function
to slow down or stop the watercraft as it
could cause you to lose control, be eject-
ed, or impact the handlebars.
This could increase the risk of back/spinal
injury (paralysis), facial injuries, and broken
legs, ankles, and other bones. You could
also damage the shift mechanism.
EX SPORT: Reverse can be used to slow
down or stop during slow-speed maneu-
vering, such as when docking. Once the
engine is idling, shift into reverse and grad-
ually increase engine speed. Make sure
that there are no obstacles or people be-
hind you before shifting into reverse.
EX DELUXE / EX LIMITED: This watercraft
is water-jet propelled. The jet pump is di-
rectly connected to the engine. This means
that jet thrust will produce some movement
whenever the engine is running and the “F”
(forward) or “R” (reverse) shift indicator is
displayed. When the “N” (neutral) shift indi-
cator is displayed, the forward and reverse
thrust are balanced to help keep the water-
craft from moving in either direction, al-
though some movement may occur.
EX DELUXE / EX LIMITED: To avoid rear-
end collisions while operating the water-
craft, check behind you before using the
RiDE lever to slow down or stop the water-craft. Make sure that there are no obstacles
or people behind you before shifting into
reverse.
Keep away from the intake grate while the
engine is on. Items such as long hair, loose
clothing, or PFD straps can become entan-
gled in moving parts, resulting in severe in-
jury or drowning.
Never insert any object into the jet thrust
nozzle 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 from
the engine shut-off switch before removing
any debris or weeds, which may have col-
lected around the jet intake.

Make sure that there are no obstacles or
people behind you before shifting into
reverse.
Do not touch the reverse gate while the
RiDE lever is being operated, otherwise
you could be pinched.
If the RiDE lever and throttle lever are
being operated at the same time, do not
release only the RiDE lever. Otherwise,
the watercraft could accelerate more
quickly than expected, which may lead
to an accident.
The RiDE lever and throttle lever can be oper-
ated to change the forward or rearward
movement of the watercraft only when the
engine is running. When the RiDE lever is
squeezed, the reverse gate lowers and de-
flects the water jet being discharged from the
jet thrust nozzle so that the watercraft moves
in reverse or is in neutral. When the throttle le-
ver is squeezed, the reverse gate rises and
the watercraft moves forward.
TIP:
This model is equipped with a function
which limits the engine speed in reverse.
When the engine is started, the reverse
gate automatically moves to the neutral po-
sition.
To shift into reverse:
(1) Release the throttle lever.
(2) Squeeze the RiDE lever. The reverse gate will lower, the engine speed will in-
crease, the watercraft will start moving in reverse, and the “R” (reverse) shift indi-
cator will be displayed.
To shift into neutral from reverse:
Release the RiDE lever. The reverse gate will
automatically return to the neutral position

and the “N” (neutral) shift indicator will be dis-
played.
TIP:
Although the neutral position helps keep the
watercraft from moving even when the en-
gine is running, some movement may occur.To shift into forward:
(1) Release the RiDE lever.
(2) Squeeze the throttle lever. The reverse
gate will rise completely, the engine
speed will increase, the watercraft will
start moving forward, and the “F” (for-
ward) shift indicator will be displayed.

TIP:
If the RiDE lever is squeezed while the throttle
lever is squeezed, the watercraft will slow
down, and once stopped, move in reverse.
To shift into neutral from forward:
(1) Release the throttle lever.
(2) Lightly squeeze and release the RiDE le-ver. The “N” (neutral) shift indicator will
be displayed.
TIP:
If the RiDE lever is squeezed continuously,
the reverse gate will move to the reverse po-
sition.
