Hazard information
When transporting or storing your water-
craft, always place the fuel cock knob in
the “OFF” position, otherwise gasoline
may overflow from the carburetor.
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.

Watercraft characteristics
Jet thrust turns the watercraft. Releasing
the throttle completely produces only min-
imum thrust. If you are traveling at speeds
above trolling, you will have rapidly
decreasing ability to steer without throttle.
You may still have some turning ability
immediately after releasing the throttle,
but once the engine slows down, the
watercraft will no longer respond to han-
dlebar input until you open the throttle
again or you reach a trolling speed. Prac-
tice 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.
Keep away from intake grate 1 while 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.
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.

Starting the engine
WARNING@ Never start the engine or let it run for any
length of time in an enclosed area.
Exhaust fumes contain carbon monox-
ide, a colorless, odorless gas that may
cause loss of consciousness and death
within a short time. Always operate the
watercraft in an open area.
@
1. Launch the watercraft in water free from
weeds and debris and at least 60 cm
(2 ft) deep.
WARNING@ Never operate in water that is less than
60 cm (2 ft) deep, otherwise you increase
your chance of hitting a submerged
object, which could result in injury.
@
CAUTION:@ Never operate in water that is less than
60 cm (2 ft) deep, otherwise pebbles or
sand could be sucked into the jet intake,
causing impeller damage or engine over-
heating.

Towing the watercraft
If the watercraft becomes inoperative in
the water, it can be towed to shore.
If the watercraft must be towed in an
emergency using a towline, the operator
should ride the watercraft, holding onto the
handlebars.
CAUTION:@ Tow the watercraft at 5 mph (8 km/h) or
less, otherwise water could enter the
engine through the exhaust passages
or through the air intake and flood the
engine compartment if it is towed too
fast.
Tow the watercraft using the bow
eye1 only.
The bow must be kept up out of the
water during towing to prevent water
from entering the engine compart-
ment.
@
WARNING@ The watercraft should only be towed in
an emergency.
The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down. A
good rule of thumb is a towline that is
three times the combined length of the
towing boat and the watercraft.
The operator of the towing boat must
keep speed to a minimum and avoid
traffic or obstacles which could be a
hazard to the rider on the watercraft.
