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, go too close to other
boats, or go too fast for the traffic condi-
tions.
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 / EX LIMITED: Take early ac-
tion to avoid collisions. Remember, water-
craft and other boats do not have brakes.
In addition, the Reverse with Intuitive De-
celeration Electronics (RiDE) system is not
a braking device for avoiding dangerous
situations. The RiDE system is an electron-
ic system for controlling the engine speed
and reverse gate, which is located near the
jet thrust nozzle. The RiDE lever located atthe left handlebar grip can be used to
change the direction of the jet thrust so that
the watercraft moves in reverse or is in neu-
tral. The RiDE system assists the operator
when slowing down and during slow-
speed maneuvering, such as launching,
beaching, and docking.
EX DELUXE / EX LIMITED: Avoid sharp
turns, slowing down rapidly by squeezing
the RiDE lever forcefully, and other maneu-
vers that make it hard for others to avoid
you or understand 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—as with other
powerboats, you need throttle to steer. Al-
ways 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.
Avoid aggressive operation, sharp turns,
and unexpected acceleration that can
cause you to be thrown off. Do not jump
waves or wakes—jumping can cause inju-
ries such as back or spinal injuries (paraly-
sis), facial injuries, and broken legs, ankles,
and other bones. Improper operation can
result in severe injury or death.
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

Operating your watercraftEWJ00511
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 9. 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:
225 kg (496 lb)
Load is the total weight of cargo, op-
erator, and passengers.

(8) Look in all directions, start the engine, and then start off slowly.
EJU33084Starting offEWJ00713
To avoid collisions:
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, go too
close to other boats, or go too fast for
the traffic conditions. Avoid sharp turns
or other maneuvers that make it hard for
others to avoid you or understand where
you are going. Avoid areas with sub-
merged 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—as with other power-
boats, you need throttle to steer.
ECJ01341
Never run the engine in water that is less
than 60 cm (2 ft) deep from the bottom of
the watercraft, otherwise pebbles or sand
could be sucked into the jet intake, caus-
ing impeller damage and engine overheat-
ing.
