EJU30680
The safe use and operation of this water-
craft is dependent upon the use of proper
riding techniques, as well as upon the
common sense, good judgment, and ex-
pertise of the operator. Before using this
watercraft, make sure that its use is per-
mitted under local laws, bylaws, and regu-
lations, and always operate the watercraft
in full conformity with any requirements
and limitations imposed. Every operator
should know the following requirements
before riding the watercraft.

Before operating the watercraft, read this
owner’s/operator’s manual, the Riding
Practice Guide, and all warning and caution
labels on the watercraft. These materials
should give you an understanding of the
watercraft and its operation.

Never allow anyone to operate this water-
craft until they too have read this own-
er’s/operator’s manual, the Riding Practice
Guide, and all warning and caution labels.
EJU30700

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
