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.
EJU01980
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.

Enjoy your watercraft
responsibly
You share the areas you enjoy when
riding your watercraft with others and with
nature. So your enjoyment includes a
responsibility to treat these other people,
and the lands, waters, and wildlife with
respect and courtesy.
Whenever and wherever you ride, think of
yourself as the guest of those around you.
Remember, for example, that the sound of
your watercraft may be music to you, but it
could be just noise to others. And the excit-
ing splash of your wake can make waves
others won’t enjoy. Avoid riding close to
shoreline homes and waterfowl nesting
areas or other wildlife areas, and keep a
respectful distance from fishermen, other
boats, swimmers, and populated beaches.
When travel in areas like these is unavoid-
able, ride slowly and obey all laws.
Remember that pollution can be harmful
to the environment. Do not refuel or add oil
where a spill could cause damage to nature.
Remove your watercraft from the water and
move it away from the shoreline before refu-
eling. And keep your surroundings pleasant
for the people and wildlife that share the
waterways: don’t litter!
When you ride responsibly, with respect
and courtesy for others, you help ensure
that our waterways stay open for the enjoy-
ment of a variety of recreational opportuni-
ties.

Fuel cock knob
The fuel cock supplies fuel from the fuel
tank to the carburetors.
The fuel cock knob 1 positions are
explained as follows and are shown in the
illustration.
OFF:
With the fuel cock knob in this position,
fuel does not flow. Always turn the fuel cock
knob to this position when the engine is not
running.
ON:
With the fuel cock knob in this position,
fuel flows to the carburetors. Turn the fuel
cock knob to this position when starting the
engine and operating the watercraft.
RES:
This indicates reserve. With the fuel cock
knob in this position, the fuel reserve is
made available. Tur n the fuel cock knob to
this position if you run out of fuel while oper-
ating the watercraft. When this occurs,
refuel as soon as possible and be sure to
turn the fuel cock knob back to “ON”!

Engine stop switch
Push this switch 1 (red button) to stop
the engine normally.
EJU01016
Engine shut-off switch
Insert the clip 1, on the end of the engine
shut-off cord 2, under the engine shut-off
switch 3 (black button). The engine will stop
automatically when the clip is removed from
the switch, such as if the operator falls off
the watercraft.
WARNING@ Always attach the engine shut-off cord
to your wrist and the clip to the engine
shut-off switch BEFORE starting the
engine.
To prevent accidental starting of the
engine or unauthorized use by chil-
dren or others, always remove the clip
from the shut-off switch when the
engine is not running.

Choke lever
Starting a cold engine requires a richer
air-fuel mixture, which is supplied by the
choke.
Move the lever 1 in direction a to turn
the choke on.
Move the lever in direction b to turn the
choke off.

Bow down
Turn the grip to A or B and the bow will
go down while the watercraft is on plane.
Bow down puts more of the bow in the
water. This gives the watercraft more “hook,”
which enhances turning performance. This
position will also help the watercraft get up
on plane more quickly.
At higher speeds, however, the watercraft
will have greater tendency to “bow steer”
and follow waves and wakes in the water.
Fuel economy and maximum speed are also
reduced.
EJU01024
Bow up
Turn the grip to C or D and the bow will
go up while the watercraft is on plane.
Bow up puts less of the bow in the water.
There is less water resistance, so straight-
ahead acceleration when on plane and top
speed are enhanced.
In some conditions, however, the water-
craft may tend to “porpoise” (hop in the
water). If the watercraft is porpoising,
choose neutral or bow down.
EJU01979
Handgrip
The handgrip 1 provides a handhold for
boarding the watercraft.
WARNING@ Do not use the handgrip to lift the water-
craft. The watercraft could fall, which
could result in severe injury.
