Safety information

EJU30762
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 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
throttle to steer. Always check throttle and
steering controls before starting the water-
craft.
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 broken legs,
ankles, 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 wa-
tercraft.
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 water-
craft, but make sure you stay a safe dis-
tance away. It’s good, common sense.
Never operate in water that is less than 60
cm (2 ft) deep from the bottom of the wa-
tercraft, otherwise you increase your chan-
ce of hitting a submerged object, which
could result in injury.
This watercraft is not equipped with light-
ing required for night operation. Do not op-
erate the watercraft after sunset or before
dawn, otherwise you increase the risk of

will not start. Also, the starter motor could
be damaged.
[ECJ01041]
The engine will not start when the clip is re-
moved from the engine shut-off switch.
EJU31212Throttle lever
The throttle lever increases the engine speed
when the lever is squeezed.
The throttle lever returns automatically to its
fully closed (idle) position when released.
EJU35933Steering system
By turning the handlebars in the direction you
wish to travel, the angle of the jet thrust noz-zle is changed, and the direction of the water-
craft is changed accordingly.
Since the strength of the jet thrust determines
the speed and degree of a turn, throttle must
always be applied when attempting a turn,
except at trolling speed.
The angle of the jet thrust nozzle can be ad-
justed to suit operator preference. (See page
57 for information on adjusting the jet thrust
nozzle angle.)
EJU31273Steering pole
The steering pole can be moved up or down
to change the height of the handlebars.
