Cruising limitations
Scan constantly for people, objects, and
other watercraft. Be alert for conditions
that limit your visibility or block your vision
of others.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft.
Do not follow directly behind watercraft or
other boats.
Do not go near others to spray or splash
them with water.
Avoid sharp turns or other maneuvers
that make it hard for others to avoid you or
understand where you are going.
Avoid areas with submerged objects or
shallow water.
Take early action to avoid collisions.
Remember, watercraft and other boats do
not have brakes.
Do not release the throttle when trying to
steer away from objects—you need throt-
tle to steer. Always check throttle and
steering controls before starting the
watercraft.
Ride within your limits and avoid aggres-
sive maneuvers to reduce the risk of loss
of control, ejection, and collision.
This is a high performance boat—not a
toy. Sharp turns or jumping wakes or
waves can increase the risk of back/spinal
injury (paralysis), facial injuries, and bro-
ken legs, ankles and other bones. Do not
jump wakes or waves.
Do not operate the watercraft in rough
water, bad weather or when visibility is
poor; this may lead to an accident caus-
ing injury or death. Be alert to the possi-
bility of adverse weather. Take note of
weather forecasts and the prevailing
weather conditions before setting out on
your watercraft.
As with any water sport, you should not
operate your watercraft without someone
else nearby. If you operate further than
swimming distance from shore, you
should be accompanied by another boat
or watercraft, but make sure you stay a
safe distance away. It’s good, common
sense!
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.

Jumping the battery
If the watercraft battery has run down, the
engine can be started using a 12-volt bat-
tery and jumper cables.
WARNING@ Battery electrolyte is poisonous and dan-
gerous, causing severe burns, etc. Elec-
trolyte contains sulfuric acid. Avoid
contact with skin, eyes or clothing.
Antidotes
External: Flush with water.
Internal: Drink large quantities of water
or milk. Follow with milk of magnesia,
beaten egg or vegetable oil. Call physi-
cian immediately.
Eyes: Flush with water for 15 minutes
and get prompt medical attention.
Batteries produce explosive gases. Keep
sparks, flame, cigarettes, etc. well away.
If using or charging the battery in an
enclosed space, make sure that it is well
ventilated. Always shield your eyes when
working near batteries.
KEEP OUT OF THE REACH OF CHILDREN.

Connecting the jumper cables
1. Connect the positive (+) jumper cable 1
to the positive (+) terminals of both bat-
teries.
2. Connect one end of the negative (–)
jumper cable 2 to the negative (–) termi-
nal of the booster battery 3.
3. Connect the other end of the negative (–)
cable to an unpainted bolt on the cylinder
head.
CAUTION:@ Do not connect the end of the jumper
cable to the negative (–) terminal on the
watercraft battery! Be sure all connec-
tions are secure and correct before
attempting to start the engine. Any
wrong connection may damage the elec-
trical system.
@
4. Start the engine, and then disconnect
the cables by reversing the steps above.
CAUTION:@ Never push the start switch while the
engine is running.
Do not operate the start switch for
more than 5 seconds, otherwise the
battery will be discharged and the
engine will not start. Also, the starter
motor may be damaged. If the engine
does not start in 5 seconds, release
the start switch, wait 15 seconds, and
try again.
