Engine data recording
This model’s ECM stores certain engine data
to assist in the diagnosis of malfunctions and
for research, statistical analysis and develop-
ment purposes.
Although the sensors and recorded data will
vary by model, the main data points are:
Engine status and engine performance
data
This data will be uploaded only when a spe-
cial Yamaha diagnostic tool is attached to the
engine, such as when maintenance checks or
service procedures are performed.
Yamaha will not disclose this data to a third
party except in the following cases. In addi-
tion, Yamaha may provide engine data to a
contractor in order to outsource services re-
lated to the handling of the engine data. Even
in this case, Yamaha will require the contrac-
tor to properly handle the engine data we
provided and Yamaha will appropriately
manage the data.
With the consent of the boat owner
Where obligated by law
For use by Yamaha in litigation
For general Yamaha-conducted research
purposes when the data is not related to an
individual engine or owner

EJU30675
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. 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, the Riding Instruction card,
and all labels on the watercraft. Also, watch
the WaveRunner Basic Orientation Video
linked to the following QR code.
https://yamahawaverunners.com/orientati
on
A DVD is also available at your nearest
dealer for your convenience.
These materials should give you an under-
standing of the watercraft and its opera-
tion.
Never allow anyone to operate this water-
craft until they too have read this own-
er’s/operator’s manual, the Riding Practice
Guide, the Riding Instruction card, and all
labels, and, if possible, watched the
WaveRunner Basic Orientation Video.
Showing them the video may help reinforce
the information contained in these materi-
als.
EJU30733
Limitations on who may
operate the watercraft
Make sure that the operator is 16 years of
age or older and has taken a boater safety
course.
Adults must supervise use by minors.
Your state (or province) may have addition-
al requirements. You can find local rules by
contacting the United States Coast Guard
(USCG), the National Association of State
Boating Law Administrators, or your local
Power Squadron.
This watercraft is designed to carry the op-
erator and up to 2 passengers. Never ex-
ceed the maximum load limit or allow more
than 3 persons (or 2 persons if a wake-
boarder or water-skier is being pulled) to
ride the watercraft at any time.
Do not operate the watercraft with any pas-
sengers on board until you have consider-
able practice and experience riding alone.
Operating the watercraft with passengers
requires more skill. Take the time to be-
come accustomed to the handling charac-
teristics of the watercraft before trying any
difficult maneuvers.
Maximum load:
225 kg (496 lb)
Load is the total weight of cargo, op-
erator, and passengers.

EJU44481
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 at
the 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 cau-
se you to be thrown off. Do not jump waves
or wakes—jumping can cause injuries such
as back or spinal injuries (paralysis), facial
injuries, and broken legs, ankles, and other
bones. Improper operation can result in se-
vere 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
UF3Y16E0.book Page 12 Tuesday, August 9, 2022 11:18 AM

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
colliding with another boat, which could re-
sult in severe injury or death.
Follow navigation rules, and state/provin-
cial and local laws that apply to watercraft.
EJU43123
Operation requirements
All riders must wear a personal flotation de-
vice (PFD) that is approved by the appro-
priate authorities and is suitable for
personal watercraft use.
Wear protective clothing. Severe internal
injuries can occur if water is forced into
body cavities as a result of falling into the
water or being near the jet thrust nozzle.
You must wear shorts with neoprene (wet-
suit material) to keep water from being
forcefully injected into the rectum or vagina
during a fall backward. Riders not wearing
neoprene shorts have received severe rec-
tal, vaginal, and internal injuries resulting in
permanent damage. Normal swimwear
does not offer adequate protection.
Eye protection is recommended to keep
wind, water, and glare from the sun out of
your eyes while you operate your water-
craft. Restraining straps for eyewear are
made which are designed to float should
your eyewear fall in the water.
Footwear and gloves are recommended.
Helmets meeting Snell or DOT standards
are required for IJSBA-sanctioned races.
You must decide whether to wear a helmet
while you ride for recreation. You should
know that a helmet could help protect you

in certain kinds of accidents and that it
could injure you in others.
A helmet is designed to provide some head
protection. Although helmets cannot pro-
tect against all foreseeable impacts, a hel-
met might reduce your injuries in a collision
with a boat or other obstacle.
A helmet may have potential safety haz-
ards, as well. Falling into the water could
risk the chance of the helmet catching wa-
ter, commonly known as “bucketing”, and
the resulting strain on your neck could cau-
se choking, severe and permanent neck in-
juries, or death. A helmet could also
increase the risk of an accident if it reduces
your vision or hearing, or if it distracts you
or increases your fatigue.
How should you decide if a helmet’s poten-
tial safety benefits outweigh its potential
risks for you? Consider your particular rid-
ing conditions. Consider factors such as
your riding environment and your riding
style and ability. Also consider the likeli-
hood of traffic congestion, and the water
surface conditions.
If you decide to wear a helmet based upon
your riding circumstances, choose one
carefully. Look for a helmet designed for
personal watercraft use, if possible. Con-
sider a helmet meeting Snell or DOT stan-
dards. If you will be engaging in closed-
course competition, follow the helmet re-
quirements of the sanctioning organization.
Never operate the watercraft after consum-
ing alcohol or taking other drugs.
For reasons of safety and proper care of
the watercraft, always perform the pre-op-
eration checks listed on page 55 before op-
erating the watercraft.
The operator should grip the handlebars
firmly with both hands and the passengers
should hold on firmly, either to the person
in front of them or to the handgrip provid-
ed.
The operator and passengers should al-
ways keep their feet on the floor of the foot-
well when the watercraft is in motion.
Lifting your feet increases the chances of
losing your balance, or hitting objects out-
side the watercraft with your feet. Do not
give a ride to children if their feet cannot
reach the floor of the footwell.
Never allow a passenger to ride in front of
the operator.
Always consult your doctor on whether it is
safe for you to ride this watercraft if you are
pregnant or in poor health.
Do not attempt to modify this watercraft.
Modifications to your watercraft may re-
duce safety and reliability, and render the
watercraft unsafe or illegal for use.
Attach the engine shut-off cord (lanyard) to
your left wrist and keep it free from the han-
dlebars so that the engine stops if you, the
operator, fall off. After riding, remove the
engine shut-off cord (lanyard) from the wa-
tercraft to avoid accidental starting or un-
authorized use by children or others.
