The safe use and operation of this watercraft is dependent upon the use of proper
riding techniques, as well as upon the
common sense, good judgment, and expertise 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 Basic Orientation Video provided with
your 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 owner’s/operator’s manual, the Riding Practice
Guide, the Riding Instruction card, and all
labels, and, if possible, watched the Basic
Orientation Video.
Showing them the video may help reinforce
the information contained in these materials.
EJU30690
Limitations on who may
operate the watercraft
● Yamaha recommends a minimum operator
age of 16 years old.
Adults must supervise use by minors.
Know the operator age and training requirements for your state. A boating safety
course is recommended and may be required in your state. 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 only. Never have more than one person on the watercraft at any time.
7
Page 13
Safety information
EJU30761
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 understand 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 watercraft.
● Ride within your limits and avoid aggressive
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, 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 adverse weather. Take note of weather forecasts 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 swimming 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 from the bottom of the watercraft, 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
8
Page 14
Safety information
with another boat, which could result in severe injury or death.
● Follow navigation rules, and state/provin-
cial and local laws that apply to watercraft.
EJU30771
Operation requirements
● All riders must wear a U.S. Coast Guard
(USCG) approved personal flotation device
(PFD) that 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.
Normal swimwear does not adequately protect against forceful water entry into the rectum or vagina. All riders must wear a
wetsuit bottom or clothing that provides
equivalent protection. Such clothing includes thick, tightly woven, sturdy and
snug-fitting apparel such as denim, but
does not include spandex or similar fabrics,
like those used in bicycle shorts.
1 USCG approved PFD
2 Wetsuit bottom
● Eye protection is recommended to keep
wind, water, and glare from the sun out of
your eyes while you operate your watercraft. 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
9
Page 15
Safety information
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 protect
against all foreseeable impacts, a helmet
might reduce your injuries in a collision with
a boat or other obstacle.
A helmet may have potential safety hazards, as well. Falling into the water could
risk the chance of the helmet catching water, commonly known as “bucketing”, and
the resulting strain on your neck could
cause choking, severe and permanent neck
injuries, 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 potential safety benefits outweigh its potential
risks for you? Consider your particular
riding conditions. Consider factors such as
your riding environment and your riding
style and ability. Also consider the likelihood 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. Consider a helmet meeting
Snell or DOT standards. If you will be engaging in closed-course competition, follow
the helmet requirements 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-operation checks listed on page 36 before operating the watercraft.
● The operator should always keep both feet
or knees on the riding tray when the watercraft is in motion. Lifting your feet increases
the chances of losing your balance or hitting
objects outside the watercraft with your
feet.
● Always consult your doctor on whether it is
safe for you to operate this watercraft if you
are pregnant or in poor health.
● Do not attempt to modify this watercraft.
Modifications to your watercraft may reduce
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 handlebars so that the engine stops if you, the
operator, fall off. After riding, remove the
engine shut-off cord (lanyard) from the watercraft to avoid accidental starting or unauthorized use by children or others.
10
Page 16
Safety information
● Scan carefully for swimmers, and stay
away from swimming areas. Swimmers are
hard to see and you could accidentally hit
someone in the water.
● Avoid being hit by another boat. You should
always take the responsibility to watch for
traffic; other boaters may not be watching
for you. If they do not see you, or if you maneuver more quickly than other boaters expect, you risk a collision.
● Maintain a safe distance from other boats
and watercraft, and also watch for ski ropes
or fishing lines. Obey the “Rules of the
Road” and be sure to check behind you before making a turn. (See “Rules of the
Road” on page 13.)
● According to the USCG, boats under 6.1 m
(20 ft) in length like your watercraft must
carry a fire extinguisher of a B-1 classification, with a capacity of two pounds or more
when navigating in waters under USCG jurisdiction. In addition, most state and local
boating laws also require that the fire extinguisher be approved by the USCG.
EJU30830
Recommended equipment
The following items should be carried on
board your watercraft:
● Sound-signaling device
You should carry a whistle or other soundsignaling device that can be used to signal
other boats. See “Rules of the Road” for
more information.
● Visual distress signals
It is recommended that a U.S. Coast Guard
approved pyrotechnic device be stored in a
waterproof container on your watercraft. A
mirror can also be used as an emergency
signal. Contact a Yamaha dealer or the
U.S. Coast Guard for more information.
● Watch
A watch is helpful so you will know how long
you have been operating the watercraft.
● Towline
A towline can be used to tow a disabled watercraft in an emergency.
11

EJU30850
Hazard information
● When transporting or storing your water-
craft, always turn the fuel cock knob to
“OFF”, otherwise gasoline may overflow
from the carburetor.
● Never start the engine or let it run for any
length of time in an enclosed area. Exhaust
fumes contain carbon monoxide, a colorless, odorless gas that may cause loss of
consciousness and death within a short
time. Always operate the watercraft in an
open area.
EJU30880
Watercraft characteristics
● Jet thrust turns the watercraft. Releasing
the throttle lever completely produces only
minimum thrust. If you are traveling at
speeds above trolling, you will have rapidly
decreasing ability to steer without throttle.
You may still have some turning ability immediately after releasing the throttle lever,
but once the engine slows down, the watercraft will no longer respond to handlebar input until you apply throttle again or you
reach trolling speed.
Practice turning in an open area without obstacles until you have a good feel for this
maneuver.
● This watercraft is water-jet propelled. The
jet pump is directly connected to the engine.
This means that jet thrust will produce some
movement whenever the engine is running.
There is no “neutral” position.
● Keep away from the intake grate while the
engine is on. Items such as long hair, loose
clothing, or PFD straps can become entangled in moving parts, resulting in severe injury or drowning.
● Never insert any object into the jet thrust
nozzle while the engine is running. Severe
injury or death could result from coming in
12

contact with the rotating parts of the jet
pump.

● Stop the engine and remove the clip from
the engine shut-off switch before removing
any debris or weeds, which may have collected around the jet intake.

● Avoid forceful jet thrust and limited visibility
while reboarding. Get to a standing or
kneeling position quickly, but do not expose
yourself to the forceful jet thrust.
EJU30961
Rules of the Road
Your Yamaha watercraft is legally considered a powerboat. Operation of the watercraft must be in accordance with the rules
and regulations governing the waterway
on which it is used.
Just as there are rules that apply when you
are driving on streets and highways, there are
waterway rules that apply when you are operating your watercraft. These rules are used internationally, and are also enforced by the
United States Coast Guard and local agencies. You should be aware of these rules, and
follow them whenever you encounter another
vessel on the water.
Several sets of rules prevail according to geographic location, but are all basically the same
as the International Rules of the Road. The
rules presented here in this owner’s/opera-
tor’s manual are condensed, and have been
provided for your convenience only. Consult
your local U.S. Coast Guard Auxiliary or Department of Motor Vehicles for a complete set
of rules governing the waters in which you will
be operating your watercraft.
Steering and sailing rules
Whenever two vessels on the water meet one
another, one vessel has the right-of-way; it is
called the “stand-on” vessel. The vessel that
does not have the right-of-way is called the
“give-way” or “burdened” vessel. These rules
determine which vessel has the right-of-way,
and what each vessel should do.
Stand-on vessel
The vessel with the right-of-way has the duty
to continue its course and speed, except to
avoid an immediate collision. When you maintain your direction and speed, the other vessel
will be able to determine how best to avoid
you.
13
Page 19
Safety information
Give-way vessel
The vessel which does not have the right-ofway has the duty to take positive and timely
action to stay out of the way of the stand-on
vessel. Normally, you should not cross in front
of the vessel with the right-of-way. You should
slow down or change directions briefly and
pass behind the other vessel. You should always move in such a way that the operator of
the other vessel can see what you are doing.
The General Prudential Rule regarding the
right-of-way is that if a collision appears unavoidable, neither boat has the right-of-way.
Both boats must avoid the collision.
In other words, follow the standard rules except when a collision will occur unless both
vessels try to avoid each other. If that is the
case, both vessels become give-way vessels.
Rules when encountering vessels
There are three main situations that you may
encounter with other vessels which could lead
to a collision unless the Steering Rules are followed:
Meeting: you are approaching another vessel
head-on
Crossing: you are traveling across another
vessel’s path
Overtaking: you are passing or being passed
by another vessel
In the following illustration, your watercraft is
in the center. You should give the right-of-way
to any vessels shown in the white area (you
are the give-way vessel). Any vessels in the
shaded area must yield to you (they are the
give-way vessels). Both you and the meeting
vessel must alter course to avoid each other.
Meeting
If you are meeting another power-driven vessel head on, and are close enough to run the
risk of collision, neither of you has the right-ofway. Both of you should alter course to avoid
an accident. You should keep the other vessel
on your port (left) side. This rule does not apply if both of you will clear one another if you
continue on your set course and speed.
Crossing
When two power-driven vessels are crossing
each other’s path close enough to run the risk
of collision, the vessel which has the other on
the starboard (right) side must keep out of the
way of the other. If the other vessel is on your
starboard (right) side, you must keep out of its
way; you are the give-way vessel. If the other
vessel is on your port (left) side, remember
that you should maintain course and direction,
14
Page 20
Safety information
provided the other vessel gives you the rightof-way as it should.
Overtaking
If you are passing another vessel, you are the
give-way vessel. This means that the other
vessel is expected to maintain its course and
speed. You must stay out of its way until you
are clear of it. Likewise, if another vessel is
passing you, you should maintain your speed
and direction so that the other vessel can
steer itself around you.
Other special situations
There are three other rules you should be
aware of when riding your watercraft around
other vessels.
Narrow channels and bends
When navigating in narrow channels, you
should keep to the right when it is safe and
practical to do so. If the operator of a powerdriven vessel is preparing to go around a
bend that may obstruct the view of other water
vessels, the operator should sound a prolonged blast of four to six seconds on the
whistle. If another vessel is around the bend,
it too should sound the whistle. Even if no reply is heard, however, the vessel should still
proceed around the bend with caution. If you
navigate such waters with your watercraft,
you will need to carry a portable air horn,
available from local marine supply stores.
Fishing vessel right-of-way
All vessels fishing with nets, lines, or trawls
are considered to be “fishing vessels” under
the International Rules. Vessels with trolling
lines are not considered fishing vessels. Fishing vessels have the right-of-way regardless
of position. Fishing vessels cannot, however,
impede the passage of other vessels in narrow channels.
Sailing vessel right-of-way
Sailing vessels should normally be given the
right-of-way. The exceptions to this are:
(1) When the sailing vessel is overtaking the
power-driven vessel, the power-driven
vessel has the right-of-way.
(2) Sailing vessels should keep clear of any
fishing vessel.
(3) In a narrow channel, a sailing vessel
should not hamper the safe passage of a
power-driven vessel that can navigate
only in such a channel.
Reading buoys and other markers
The waters of the United States are marked
for safe navigation by the lateral system of
buoyage. Simply put, buoys and markers
have an arrangement of shapes, colors, numbers, and lights to show which side of the
buoy a boater should pass on when navigating in a particular direction. The markings on
these buoys are oriented from the perspective
of being entered from seaward (the boater is
going towards the harbor). Red buoys are
passed on your starboard (right) side when
proceeding from open water into the harbor,
and black buoys are to your port (left) side. An
easy way to remember the meaning of the
colors is the phrase “red right returning”.
When navigating out of the harbor, your position with respect to the buoys should be reversed; red buoys should be to port and black
buoys to starboard.
15
Page 21
Safety information
Many bodies of water used by boaters are entirely within the boundaries of a particular
state. The Uniform State Waterway Marking
System has been devised for these waters.
This system uses buoys and signs with distinctive shapes and colors to show regulatory
or advisory information. These markers are
white with black letters and orange borders.
They signify speed zones, restricted areas,
danger areas, and general information.
16
Page 22
Safety information
Remember, markings may vary by geographic location. Always consult local boating authorities before riding your watercraft in
unfamiliar waters.

Enjoy your watercraft
responsibly
You share the areas you enjoy when riding
your watercraft with others and with nature.
So your enjoyment includes a responsibility to
treat these other people, and the lands, waters, and wildlife with respect and courtesy.
Whenever and wherever you ride, think of
yourself as the guest of those around you. Remember, for example, that the sound of your
watercraft may be music to you, but it could be
just noise to others. And the exciting splash of
your wake can make waves others won’t enjoy.
Avoid riding close to shoreline homes and waterfowl nesting areas or other wildlife areas,
and keep a respectful distance from fishermen, other boats, swimmers, and populated
beaches. When travel in areas like these is
unavoidable, ride slowly and obey all laws.
Proper maintenance is necessary to ensure
that the exhaust emission and sound levels of
your watercraft will continue to be within regulated limits. You have the responsibility to
make sure that the recommended maintenance in this owner’s/operator’s manual is
carried out.
Remember, pollution can be harmful to the
environment. Do not refuel or add oil where a
spill could cause damage to nature. Remove
your watercraft from the water and move it
away from the shoreline before refueling. Dispose of water and any fuel and oil residue in
the engine compartment according to local
regulations. And keep your surroundings
pleasant for the people and wildlife that share
the waterways: don’t litter.
When you ride responsibly, with respect and
courtesy for others, you help ensure that our

waterways stay open for the enjoyment of a
variety of recreational opportunities.

Cooling water pilot outlet
When the engine is running, some of the cooling water that is circulated in the engine is discharged from the cooling water pilot outlet.
1 Cooling water pilot outlet
There is a cooling water pilot outlet on the port
(left) side of the watercraft. To check for proper operation of the cooling system, make sure
that water is being discharged from the cooling water pilot outlet. If water is not being discharged from the outlet, stop the engine and
25

check the jet intake for clogging. (See page
70 for information on the jet intake.)
TIP:
● If the cooling water passages are dry, it will
take about 20 seconds for the water to
reach the outlet after the engine is started.
● Water discharge may not be constant when
the engine is running at idling speed. If this
occurs, apply a little throttle to make sure
that water discharges properly.
EJU40321
Water separator
The water separator prevents water from entering the fuel tank by collecting any water that
has entered the fuel tank breather hose if the
watercraft was capsized.
If water has collected in the water separator,
drain it by loosening the drain screw.
1 Water separator
To drain water from the water separator:
(1) Place a drain pan or dry cloth under the
water separator.
(2) Gradually loosen the drain screw to drain
the water. Catch the draining water in the
drain pan or soak it up with the dry cloth
so that it does not spill into the engine
compartment. If any water spills into the

Engine overheat warning system
If the engine temperature rises significantly,
the engine overheat warning system will activate and the engine speed will be limited to
about 3400 r/min to help prevent damage.
If the engine overheat warning system is activated, immediately reduce the engine speed,
return to shore, and then make sure that water is being discharged from the cooling water
pilot outlet while the engine is running. If there
is no discharge of water, stop the engine, and
then check the jet intake for clogging. (See
page 70 for information on the jet intake.)
NOTICE: If you cannot locate and correct
the cause of the overheating, consult a
Yamaha dealer. Continuing to operate at
higher speeds could result in severe engine damage.

WARNING
● Gasoline and gasoline vapors are ex-
tremely flammable. To avoid fires and
explosions and to reduce the risk of injury when refueling, follow these instructions.
● Gasoline is poisonous and can cause in-
jury or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline, inhale a
lot of gasoline vapor, or get some gasoline in your eyes, see your doctor immediately. If gasoline spills on your skin,
wash with soap and water. If gasoline
spills on your clothing, change your
clothes.

NOTICE
● Do not use leaded gasoline. Leaded gas-
oline can seriously damage the engine.
● Avoid getting water and contaminants in
the fuel tank. Contaminated fuel can
cause poor performance and engine
damage. Use only fresh gasoline that
has been stored in clean containers.
Recommended fuel:
Regular unleaded gasoline with a minimum octane rating of
Gasohol containing ethanol can be used if
ethanol content does not exceed 10% and the
fuel meets the minimum octane ratings. E-85
is a fuel blend containing 85% ethanol and
therefore must not be used in this watercraft.
All ethanol blends containing more than 10%
ethanol can cause fuel system damage or engine performance problems.
Yamaha does not recommend gasohol containing methanol because it can cause fuel
system damage and engine performance
problems.

Reserve:
5.5 L (1.5 US gal, 1.2 Imp.gal)
(6) Stop filling when the fuel level just reach-
es the bottom of the filler tube. Do not fill
up the filler tube. Because fuel expands
when it heats up, heat from the engine or
the sun can cause fuel to spill out of the
fuel tank. Do not leave the watercraft with
a full tank in direct sunlight.
(7) Wipe up any spilled fuel immediately with
a dry cloth.
(8) Securely install the fuel filler cap by tight-
ening it until it clicks.

Operating your watercraft
EWJ00510
WARNING
Before operating your watercraft, become
familiar with all of the controls. Consult a
Yamaha dealer about any control or function that you do not fully understand. Failure to understand how the controls work
could cause an accident or prevent you
from avoiding an accident.
EJU32913
Getting to know your watercraft
Operating your watercraft requires skills acquired through practice over a period of time.
Take the time to learn the basic techniques
well before attempting more difficult maneuvers.
Operating your new watercraft can be a very
enjoyable activity, providing you with hours of
pleasure. However, it is essential to familiarize yourself with the operation of the watercraft to achieve the skill level necessary to
enjoy riding safely.
Before operating this watercraft, read this
owner’s/operator’s manual, the Riding Practice Guide, the Riding Instruction card, and all
labels on the watercraft. Pay particular attention to the safety information beginning on
page 7. Also, watch the Basic Orientation Video provided with your watercraft. These materials should give you an understanding of the
watercraft and its operation.
Remember: This watercraft is designed to
carry the operator only. Never have more than
one person on the watercraft at any time.
EJU32974
Learning to operate your watercraft
Before operating the watercraft, always perform the pre-operation checks listed on page
36. The short time spent checking the water-
craft will reward you with added safety and reliability.
Check state and local laws before operating
your watercraft.
Operate defensively at safe speeds and keep
a safe distance away from people, objects,
and other watercraft. Select a wide area to
practice maneuvering in, where there is good
visibility and light boat traffic.
Use the buddy system—operate with someone nearby. Scan constantly for people, objects, and other watercraft. Be alert for
conditions that limit your visibility or block your
vision of others.
You should grip the handlebars firmly and get
to a standing or kneeling position quickly.
Keep both feet or knees on the riding tray
when the watercraft is in motion.
EJU33171
Operating positions
After you are underway, you may choose to
kneel or stand, depending upon watercraft
speed, your skill level, and your preference.
Here are some guidelines.
Kneeling
It is easier to maintain your balance when
kneeling than when standing. This position is
recommended when traveling at sub-planing
speeds. (At sub-planing speeds, there is a
44
Page 50
Operation
wake, but the watercraft is moving through the
water rather than skimming on top of it.)
At very slow speeds, it may be necessary to
support your upper-body weight with your elbows resting on the gunwales, trailing your
legs in the water.
Standing
After you are comfortable handling the watercraft from a kneeling position, try standing as
the watercraft gains speed. The watercraft will
become easier to balance as the speed increases, because jet thrust provides stability
as well as directional control. When you are
moving slowly, or preparing to stop, you will
probably need to return to the kneeling position to maintain your balance.
If the watercraft is launched from a trailer,
someone should make sure that waves do not
push the watercraft into the trailer.
After the watercraft is in the water, turn it
around so that the bow faces the direction you
wish to go.
EJU32835
Starting the engine on water
EWJ01520
WARNING
Do not apply throttle when others are at
the rear of the watercraft. Turn the engine
off or keep it at idle. Water and debris exiting the jet thrust nozzle can cause severe
injury.
To start the engine:
(1) Move the watercraft to an area that is free
from weeds and debris, and has a water
depth of at least 60 cm (2 ft) from the bottom of the watercraft. NOTICE: 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, causing impeller damage and engine overheating.

WARNING
● Do not release the throttle lever when
trying to steer away from objects—you
need throttle to steer. A collision could
result in severe injury or death.
● When operating at higher speeds, make
gradual turns or slow down before turning. Sharp high-speed turns may cause

throwing the operator overboard, which
could cause an injury.
EJU41170
Operating the watercraft
When the engine is running, the watercraft will
move forward even if the throttle lever is in the

Steering control depends on the combination
of handlebar position and the amount of throttle.
Water sucked in through the intake grate is
pressurized by the impeller in the jet pump. As
the pressurized water is expelled from the
pump through the jet thrust nozzle, it creates
thrust to move and steer the watercraft. The
higher the engine speed, the more thrust produced.
The amount of jet thrust, in addition to the position of the handlebars, determines how
sharply you turn.

Operation
A. More throttle produces higher thrust, so
the watercraft will turn more sharply.
B. Less throttle produces lower thrust, so
the watercraft will turn more gradually.
alone using just the amount of thrust
available at idle.
D. If the engine is stopped while riding, there
is no thrust. The watercraft will go straight
even though the handlebars are turned.
C. Releasing the throttle lever completely
produces only minimum thrust. If you are
traveling at speeds above trolling, you will
have rapidly decreasing ability to steer
without throttle. You may still have some
turning ability immediately after releasing
the throttle lever, but once the engine
slows down, the watercraft will no longer
respond to handlebar input until you apply throttle again or you reach trolling
speed.
At trolling speed, the watercraft can be
turned gradually by handlebar position
You need throttle to steer.
To maintain your balance, lean into a turn.
How much you lean depends on the sharpness of the turn and your traveling speed. In

general, the higher the speed or the sharper
the turn, the more you lean.
EJU33272
Stopping the watercraft
The watercraft is not equipped with a separate braking system. It is stopped by water resistance when the throttle lever is released.
From full speed, the watercraft comes to a
complete stop in approximately 90 m (300 ft)
after the throttle lever is released or the engine is stopped, although this distance will
vary depending on many factors, including
gross weight, water surface conditions, and
wind direction. The watercraft slows down as
soon as the throttle lever is released, but will
coast for a distance before fully stopping. If
you are not sure you can stop in time before
hitting an obstacle, apply throttle and turn in
another direction.
EWJ00722
WARNING
● Allow adequate stopping distance.
● Take early action to avoid collisions. Re-
member, watercraft and other boats do
not have brakes.
● Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft to give you
time to stop.
● Do not shut the engine off when slowing
down in case you need engine power to
steer away from a boat or other obstacle
that comes into your path.

WARNING
Avoid forceful jet thrust and limited visibility while reboarding. Get to a standing or
kneeling position quickly, but do not expose yourself to the forceful jet thrust.
ECJ01340
NOTICE
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, causing impeller damage and engine overheating.
Even though it is easier to start in shallow water, you must learn deep-water boarding first.
You will inevitably fall off, so be sure you know
how to get back on the watercraft once you
are away from shore.
EJU33104
Boarding and starting in shallow water
Be sure to learn the deep-water starting method before operating the watercraft in water
where it is too deep for you to stand. (See
page 51 for the deep-water starting method.)
(1) Launch the watercraft in water free from
weeds and debris and at least 60 cm (2 ft)
deep from the bottom of the watercraft.
NOTICE: 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, causing impeller
damage and engine overheating.

(2) Attach the engine shut-off cord (lanyard)
to your left wrist, and then attach the clip
to the engine shut-off switch.
(3) Grip the handlebars with both hands.
Place one knee on the riding tray and balance there.
The watercraft is less stable when at a standstill or at a slow speed. It takes skill to keep the
watercraft upright when starting.

Emergency procedures
EJU34634
Cleaning the jet intake and impeller
EWJ00782
WARNING
Before attempting to remove weeds or debris from the jet intake or impeller area,
shut the engine off and remove the clip
from the engine shut-off switch. Severe injury or death could result from coming in
contact with the rotating parts of the jet
pump.
If weeds or debris gets caught in the jet intake
or impeller, cavitation can occur, causing jet
thrust to decrease even though engine speed
rises. If this condition is allowed to continue,
the engine will overheat and may seize.
NOTICE: If weeds or debris gets caught in
the jet intake, do not operate the watercraft
above trolling speed until they have been
removed.
If there is any sign that the jet intake or impeller is clogged with weeds or debris, return to
shore and check the intake and impeller. Al-
[ECJ00653]
ways stop the engine before beaching the watercraft.
(1) Place a suitable clean cloth or carpeting
underneath the watercraft to protect it
from abrasions and scratches. Turn the
watercraft on its side as shown. NOTICE:
Always turn the watercraft over onto
its port (left) side. When turning the
watercraft on its side, support the bow
so that the handlebars are not bent or
damaged.

● The operator of the towing boat must
keep speed to a minimum and avoid traffic or obstacles which could be a hazard
to the operator on the watercraft.
● The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down.
If the watercraft becomes inoperative in the
water, it can be towed to shore.

Keep your Yamaha protected even after your warranty expires with genuine Yamaha Extended
Service (Y.E.S.).
Y.E.S. is designed and administered by Yamaha Motor Corporation to provide maximum owner

satisfaction. You get uninterrupted factory-backed coverage for extra peace of mind.
Y.E.S. is flexible. You choose the plan that is right for you: 12 months, 24 months, 36 months, or
•
(on four-stroke models) 48 months beyond your warranty period.
Y.E.S. is designed and administered by the same Yamaha people who handle your warranty—
•
and it shows in the comprehensive coverage benefits. There are no mileage limitations. Coverage is not limited to “moving parts” or the “drive train” like many other plans. And Y.E.S. covers
manufacturing defects just like the warranty. See the sample contract at your Yamaha dealer to
see how comforting uninterrupted factory-backed protection can be.
You do not have to pay anything for covered repairs. There is no deductible to pay, and repairs
•
are not “pro-rated.” You do not have any “out-of-pocket” expenses for covered repairs.
In addition, Travel and Recreation Interruption Protection (TRIP) is included at no extra cost.
•
TRIP gives you up to $150 reimbursement per occurrence for any reasonable expenses you
incur because your Yamaha needs covered service: replacement vehicle rental, emergency
towing, phone calls, even food and lodging when you are away from home. This superb coverage goes into effect when you purchase Y.E.S., so it applies to any warranty repairs as well as
covered repairs during your entire Y.E.S. plan period.
Y.E.S. coverage is honored at any authorized Yamaha dealer nationwide.
•
Y.E.S. coverage is transferable to a new owner if you sell or trade-in. That can make your
•
Yamaha much more valuable!
This excellent Y.E.S. plan coverage is only available to Yamaha owners like you, and only while
your Yamaha is still within the Yamaha Limited Warranty period. So visit your authorized Yamaha
dealer to get all the facts. He can show you how easy it is to protect your investment with Yamaha
Extended Service.
We urge you to act now. You will get the excellent benefits of TRIP coverage right away, and you
will rest easy knowing you will have strong factory-backed protection even after your Yamaha
Limited Warranty expires.
A special note:
If visiting your dealer is not convenient, contact Yamaha with your Primary ID number (your Owner’s
Manual shows you where to find this number). We will be happy to help you get the Y.E.S. coverage
you need.
