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, ob-
jects, 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 un-
derstand where you are going.

Avoid areas with submerged objects or
shallow water.

Take early action to avoid collisions. Re-
member, watercraft and other boats do not
have brakes.

Do not release the throttle lever when trying
to steer away from objects—you need throt-
tle to steer. Always check throttle and steer-
ing controls before starting the watercraft.

Operate within your limits and avoid ag-
gressive 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 (pa-
ralysis), facial injuries, and broken legs, an-kles, and other bones. Do not jump wakes
or waves.

Do not operate the watercraft in rough wa-
ter, bad weather, or when visibility is poor;
this may lead to an accident causing injury
or death. Be alert to the possibility of ad-
verse weather. Take note of weather fore-
casts and the prevailing weather conditions
before setting out on your watercraft.

As with any water sport, you should not op-
erate your watercraft without someone else
nearby. If you operate further than swim-
ming 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.

This watercraft is not equipped with lighting
required for night operation. Do not operate
the watercraft after sunset or before dawn,
otherwise you increase the risk of colliding

Operating your watercraft EJU32920Getting to know your watercraft
Operating your watercraft requires skills ac-
quired through practice over a period of time.
Take the time to learn the basic techniques
well before attempting more difficult maneu-
vers.
Operating your new watercraft can be a very
enjoyable activity, providing you with hours of
pleasure. However, it is essential to familiar-
ize yourself with the operation of the water-
craft to achieve the skill level necessary to
enjoy riding safely.
Before operating this watercraft, read this
owner’s/operator’s manual, the Riding Prac-
tice Guide, and all warning and caution labels
on the watercraft. Pay particular attention to
the safety information on page 7. These ma-
terials should give you an understanding of
the watercraft and its operation.
Remember: This watercraft is designed to
carry the operator only. Never have more than
one person on the watercraft at any time.
EJU32980Learning to operate your watercraft
Before operating the watercraft, always per-
form the pre-operation checks listed on page
27. The short time spent checking the water-
craft will reward you with added safety and re-
liability.
Check local laws before operating your water-
craft.
Operate defensively at safe speeds and keep
a safe distance away from people, objects,
and other watercraft. Select a wide area tolearn in, where there is good visibility and light
boat traffic.
Use the buddy system—operate with some-
one nearby. Scan constantly for people, ob-
jects, and other watercraft. Be alert for
conditions that limit your visibility or block your
vision of others.
Attach the engine shut-off cord to your left
wrist and keep it free from the handlebars so
that the engine stops if you, the operator, fall
off.
Wear a personal flotation device (PFD). The
operator must wear a PFD that is approved by
the appropriate authorities and is suitable for
personal watercraft use.
Wear protective clothing. Severe internal inju-
ries can occur if water is forced into body cav-
ities as a result of falling into the water or
being near the jet thrust nozzle. Normal swim-
wear does not adequately protect against
forceful water entry into the rectum or vagina.
The operator must wear a wetsuit bottom or
clothing that provides equivalent protection.
Such clothing includes thick, tightly woven,
sturdy and snug-fitting apparel such as den-
im, but does not include spandex or similar
fabrics, like those used in bicycle shorts. A full
wetsuit can also protect against hypothermia
(subnormal body temperature) and abra-
sions.
Footwear and gloves are recommended.

EJU33070Starting the watercraft
WARNING
EWJ00700

Scan constantly for people, objects, and
other watercraft. Be alert for conditions
that limit your visibility or block your vi-
sion 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 shal-
low water.

Take early action to avoid collisions. Re-
member, watercraft and other boats do
not have brakes. Do not release the
throttle lever when trying to steer away
from objects—you need throttle to steer.

Practice deep-water starting near shore
before riding in deep water.
The watercraft is less stable when at a stand-
still or at a slow speed. It takes skill to keep the
watercraft upright when starting.
Even though it is easier to start in shallow wa-
ter, you must learn deep-water boarding first.You will inevitably fall off, so be sure you know
how to get back on the watercraft once you
are away from shore.
EJU33101Boarding and starting in shallow water
Be sure to learn the deep-water starting meth-
od before operating the watercraft in water
where it is too deep for you to stand. (See
page 39 for the deep-water starting method.)
(1) Launch the watercraft in water free from
weeds and debris and at least 60 cm (2 ft)
deep.
WARNING
EWJ00570
Never operate in water that is less than 60
cm (2 ft) deep, otherwise you increase
your chance of hitting a submerged ob-
ject, which could result in injury.
CAUTION:
ECJ00470
Never operate in water that is less than 60
cm (2 ft) deep, otherwise pebbles or sand
could be sucked into the jet intake, caus-
ing impeller damage and engine overheat-
ing.
(2) Attach the engine shut-off cord to your left
wrist, and then attach the clip to the en-
gine shut-off switch.
(3) Grip the handlebars with both hands.
Place one knee on the riding tray and bal-
ance there.
