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.
EX / EX Sport: Take early action to avoid
collisions. Remember, watercraft and other
boats do not have brakes.
EX / EX Sport: Avoid sharp turns or other
maneuvers that make it hard for others to
avoid you or understand where you are go-
ing.
EX Deluxe: Take early action to avoid colli-
sions. Remember, watercraft and other
boats do not have brakes. In addition, the
Reverse with Intuitive Deceleration Elec-
tronics (RiDE) system is not a braking de-
vice for avoiding dangerous situations. The
RiDE system is an electronic system for
controlling the engine speed and reverse
gate, which is located near the jet thrust
nozzle. The RiDE lever located at the left
handlebar grip can be used to change the
direction of the jet thrust so that the water-craft moves in reverse or is in neutral. The
RiDE system assists the operator when
slowing down and during slow-speed ma-
neuvering, such as launching, beaching,
and docking.
EX Deluxe: Avoid sharp turns, slowing
down rapidly by squeezing the RiDE lever
forcefully, and other maneuvers that make
it hard for others to avoid you or under-
stand where you are going.
Avoid areas with submerged objects or
shallow water.
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.

Operating your watercraft
WARNING
EWJ00511
Before operating your watercraft, become
familiar with all of the controls. Consult a
Yamaha dealer about any control or func-
tion that you do not fully understand. Fail-
ure to understand how the controls work
could cause an accident or prevent you
from avoiding an accident.
EJU32965Getting 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, the Riding Instruction card, and all
labels on the watercraft. Pay particular atten-
tion to the safety information beginning on
page 10. These materials should give you an
understanding of the watercraft and its oper-
ation.
Remember: This watercraft is designed to
carry the operator and up to 2 passengers.
Never exceed the maximum load limit or al-
low more than 3 persons (or 2 persons if a
wakeboarder or water-skier is being pulled)
to ride the watercraft at any time.
EJU33006Learning to operate your watercraft
Before operating the watercraft, always per-
form the pre-operation checks listed on page
51. The short time spent checking the water-
craft will reward you with added safety and
reliability.
Check local laws before operating your wa-
tercraft.
Operate defensively at safe speeds and keep
a safe distance away from people, objects,
and other watercraft. Select a wide area to
learn 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.
You should grip the handlebars firmly and
keep both feet on the floor of the footwell. Do
not attempt to ride with passengers until your
operating skills are fully developed.Maximum load:
220 kg (486 lb)
Load is the total weight of cargo, op-
erator, and passengers.
