Safety information
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. Before using this watercraft, make sure that its use is permitted under local laws, by-laws and regulations and always operate the watercraft in full conformity with any requirements and limitations imposed. 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, and all warning and cau-
tion labels on the watercraft. These mate-
rials 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 and all warning and caution labels.
EJU00298
Limitations on who may operate the watercraft
Yamaha recommends a minimum opera-
tor age of 16 years old. Adults must supervise use by minors. Know your local operator age and training requirements.
This watercraft is designed to carry the
operator and one passenger. Never exceed the maximum load limit or allow more than 2 persons to ride the watercraft at one time.
Maximum load: 160 kg (353 lb)
Load is the total weight of cargo, opera­tor and passenger.
Do not operate the watercraft with a pas-
senger on board until you have consider­able practice and experience riding alone. Operating the watercraft with a passenger requires more skill. Take the time to become accustomed to the handling characteristics of the watercraft before trying any difficult maneuvers.

EJU00613
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.
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 bro-
ken legs, ankles and other bones. Do not
jump wakes or waves.
Do not operate the watercraft in rough
water, 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
ride your watercraft without someone else near by. If you ride further than swimming distance from shore, you should ride 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, otherwise you increase your chance of hitting a submerged object, which could result in injury.
1-10
Page 18
This watercraft is not equipped with light-
ing required for night operation. Do not
operate the watercraft after sunset or
before dawn, otherwise you increase the
risk of colliding with another boat, which
could result in severe injury or death.
EJU00735a
Operation requirements
All riders must wear a personal flotation
device (PFD) that is approved by the appropriate authorities and 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 water or being near the jet thrust nozzle. Normal swimwear does not adequately protect against forceful water entry into 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 Authority-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.
1-11
Page 19
You must decide whether to wear a hel-
met while you ride for recreation. You
should know that a helmet could help pro-
tect 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 col-
lision 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
water, commonly known as “bucketing,”
and the resulting strain on your neck
could cause choking, severe and perma-
nent 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 par-
ticular 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 cir-
cumstances, choose one carefully. Look
for a helmet designed for personal water-
craft use, if possible. If you will be engag-
ing in closed-course competition, follow
the helmet requirements of the sanction-
ing organization.
NEVER operate the watercraft after con-
suming alcohol or taking other drugs.
For reasons of safety and proper care of
the watercraft, always perform the pre­operation checks listed on page 3-5 before operating the watercraft.
The operator and passenger should
always keep both feet in the footwell when the watercraft is in motion. Lifting your feet increases your chances of losing your balance, and your feet being hit by objects outside the watercraft. Do not give a ride to a child whose feet cannot reach the floor of the footwell.
Passenger should firmly hold on to 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.
1-12
Page 20
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 wrist and keep it free from the handle-
bars so that the engine stops if the opera-
tor falls off. After riding, remove the
engine shut-off cord from the watercraft to
avoid accidental starting or unauthorized
use by children or others.
Scan carefully for swimmers and stay
away from swimming areas. Swimmers
are hard to see and you could acciden-
tally 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 you maneuver more quickly than other
boaters expect, you risk a collision.
Maintain a safe distance from other boats
or watercraft, and also watch for boats’ ski
ropes or fishing lines. Obey the “Safe
boating rules” and be sure to check
behind you before making a turn. (See
Safe boating rules on page 1-15.)
EJU00313
Hazard information
When transporting or storing your water-
craft, always place the fuel cock knob in the “OFF” position, 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.
1-13

EJU00315a
Watercraft characteristics
Jet thrust turns the watercraft. Releasing
the throttle completely produces only min-
imum 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,
but once the engine slows down, the
watercraft will no longer respond to han-
dlebar input until you open the throttle
again or you reach a trolling speed. Prac-
tice turning in an open area without
obstructions until you have a good feel for
this maneuver.
This watercraft are water-jet propelled.
The jet pump is directly connected to the
engine. This means that jet thrust will pro-
duce some movement whenever the
engine is running. There is no “neutral”
position.
Keep away from intake grate 1 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 2 while the engine is running. Severe injury or death could result from coming in contact with the rotating parts of the jet pump.
Stop the engine and remove the clip 3
from the engine shut-off switch 4 before removing any debris or weeds, which may have collected around the jet intake.

Safe boating rules
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.
EJU00322
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.
Remember that 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. 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.

EJU00354
Cooling water pilot outlet
This watercraft is equipped with a cooling
water pilot outlet.
When the engine is running, cooling
water is circulated in the engine, and then it is discharged from the pilot outlet.
To check for proper operation of the cool-
ing system, check that water is being dis­charged from the pilot outlet. If water is not being discharged from the outlet, cooling water may not be circulating in the engine. When this occurs, stop the engine and check for the cause. (See pages 2-13 and 5-4 for further instructions.)
NOTE:
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.
EJU00356
Steering system
Your watercraft can be steered by turning
the handlebars 1 the same direction you wish to travel.
When the handlebars are turned, the
angle of the jet thrust nozzle 2 is changed, and the direction of the watercraft is changed accordingly. Since the strength of the jet thrust determines the speed and direction of a turn, the throttle must always be open when attempting a turn, except at trolling speed.
2-10
Page 34
EJU00360a
Quick Shift Trim System (QSTS) selector
The QSTS selector 1 is located at the
left handlebar grip and is used to adjust the trim angle of the watercraft.
Operating the QSTS selector changes the
angle of the jet thrust nozzle vertically. This changes the trim angle of the watercraft.
There are 5 positions: 2 bow down posi-
tions A and B, neutral “N,” and 2 bow up positions C and D.
To change the trim angle:
1. Reduce engine speed to 3,000 r/min or less.
2. Squeeze the shift lock lever 2, and then turn the QSTS selector to the desired position.
3. Release the shift lock lever to lock the QSTS selector.
CAUTION:
Do not turn the QSTS selector while operating the watercraft at full throttle, otherwise damage could occur to the QSTS.
The neutral “N” position will provide good
performance for most operating conditions.
To enhance particular types of perfor-
mance, select bow down or bow up.
2-11
Page 35
Bow down
Turn the grip to A or B and the bow will
go down while the watercraft is on plane.
Bow down puts more of the bow in the water. This gives the watercraft more “hook,” which enhances turning performance. This position will also help the watercraft get up on plane more quickly.
At higher speeds, however, the watercraft will have greater tendency to “bow steer” and follow waves and wakes in the water. Fuel economy and maximum speed are also reduced.
Bow up
Turn the grip to C or D and the bow will go up while the watercraft is on plane.
Bow up puts less of the bow in the water. There is less water resistance, so straight­ahead acceleration when on plane and top speed are enhanced.
In some conditions, however, the water­craft may tend to “porpoise” (hop in the water). If the watercraft is porpoising, choose neutral or bow down.
2-12
Page 36
EJU00366
Engine overheat warning system
This model is equipped with an engine overheat warning system.
If the engine starts to overheat, the warn­ing light, the indicator for the water tempera­ture symbol, and “W.TEMP” display begin to blink. The buzzer sounds, and the engine speed will be limited to about 3,000 r/min.
When this occurs, check for water dis­charge at the cooling water pilot outlet. If there is no discharge of water, reduce the engine speed and beach the watercraft, and then check the intake grate and impeller for clogging.
WARNING
Before attempting to remove weeds or debris from the intake grate or impeller, 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.
CAUTION:
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.
NOTE:
Press any button on the multifunction meter to stop the buzzer.

PADLOC (Programmable digital locking ignition)
This feature is provided to deter unautho­rized use.
The function allows you to choose either “START” or “LOCK” mode, as the situation requires, much as you would use an ignition key in a motor vehicle. If you have previously chosen “LOCK” mode, the engine will not start unless the right code is put in to select “START” mode.
NOTE:
If you do not use the PADLOC system, it is unnecessary to perform the initial setting of the PADLOC. In this case, the “START” mode is automatically selected.
PADLOC initial setting
1. Disconnect the blue connector 1 behind
the front storage compartment.
2. After the warning light turns on, press
the “MODE” button for at least 3 seconds until the display shows “COdE.” You are ready to set your code.
2-16
Page 40
3. Select your four-letter code by pressing
the “A/SET,” “B,” or “C” buttons in a desired sequence.
NOTE:
If you do not press a button for more than 10 seconds, the display automatically turns off. This cancels the process of setting a code.
4. After code setting is complete, the
buzzer will sound 3 times and the display will show “SET.” Lastly, the display turns off and the warning light turns on again. After the meter has displayed this sequence, connect the blue connector again.
NOTE:
Your own code is kept even if the battery
terminal is disconnected.
If you forget your own code, or if you want
to change the code, do this initial setting
procedure again from the beginning.
Selecting “PADLOC” mode
Selecting the desired mode can only be done after the initial setting has been done and while the display is not lit.
1. Press the “MODE” button until the meter
displays the current mode, “START” or “LOCK.”
2. With “START” or “LOCK” displayed,
press the “MODE” button continuously for about 3 seconds until the display changes to “COdE.”

Fuel and oil
This engine uses Yamaha’s oil injection system, which provides superior lubrication by ensuring the proper oil ratio for all operat­ing conditions. No fuel premixing is neces­sary except during the engine break-in period. Simply pour gasoline into the fuel tank and oil into the oil tank.
Gasoline
WARNING
GASOLINE AND ITS VAPORS ARE HIGHLY FLAMMABLE AND EXPLOSIVE!
Do not smoke when refueling, and
keep away from sparks, flames, or
other sources of ignition.
Stop engine before refueling.
Refuel in a well-ventilated area. Do not
stand or sit on the watercraft while
refueling in case of fire.
Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.
Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level just reaches the
bottom of the filler tube. Do not fill up
the filler tube because fuel expands as
it warms up and could overflow.
Tighten the filler cap securely after
refueling.
If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.
If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.
3-1
Page 53
CAUTION:
Use only fresh gasoline that has been stored in clean containers.
Recommended gasoline:
Regular unleaded gasoline with a minimum octane rating of 86 (Pump octane number) = (R+M)/2 90 (Research octane number)
Gasohol
There are two types of gasohol: gasohol containing ethanol and that containing meth­anol.
Gasohol containing ethanol can be used if ethanol content does not exceed 10 % and the fuel meets minimum octane ratings.
Gasohol containing methanol is not rec­ommended by Yamaha because it can cause fuel system damage or engine perfor­mance problems.

Operating your watercraft
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, and all warning and caution labels on the water­craft. Pay particular attention to the safety information on pages 1-9 to 1-14. These materials should give you an understanding of the watercraft and its operation.
Remember: This watercraft is designed to carry the operator and one passenger. Never exceed the maximum load limit or allow more than 2 persons to ride the water­craft at one time.
Maximum load: 160 kg (353 lb)
Load is the total weight of cargo, opera­tor and passenger.
EJU00474
Learning to operate your watercraft
Before operating the watercraft, always perform the pre-operation checks listed on page 3-3. The short time spent checking the watercraft will reward you with added safety and reliability.
Check all 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 learn in, where you have 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.
Attach the engine shut-off cord (lanyard) to your wrist and keep it free from the han­dlebars so that the engine stops if the opera­tor falls off.
Wear a personal flotation device (PFD). All riders must wear an authority-approved PFD that is suitable for personal watercraft use.
3-19
Page 71
Wear protective clothing. Severe internal injuries can occur if water is forced into body cavities as result of falling into the water or being near the jet thrust nozzle. Normal swimwear does not adequately protect against forceful water entry into rectum and 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. A full wetsuit can also protect against hypothermia (subnormal body temperature) and abrasions.
Footwear and gloves are recommended.
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.
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.
The passenger must always wear an authority-approved PFD and a wetsuit bot­tom or equivalent.
WARNING
Do not apply throttle when anyone is at rear of watercraft. Turn engine off or keep engine at idle. Water and/or debris exit­ing the jet thrust nozzle can cause severe injury. The passenger should not attempt to board the watercraft if the operator is applying throttle.
Do not give a ride to a child whose feet cannot reach the floor of the footwell. The passenger should hold on firmly to the oper­ator and keep both feet in the footwell.
WARNING
When a passenger is on board, make sure that he or she is holding on firmly and has his or her feet in the footwell before you start to accelerate.
EJU00736
Riding watercraft with a passenger
When a passenger is on board with the operator, the watercraft handles differently, and is not as easy to maneuver, so operat­ing it requires a higher degree of skill. Before attempting to operate the watercraft with a passenger on board, the operator must practice operating the watercraft alone enough to be able to acquire the necessary skills.

and keep a safe distance away from people, objects, and other watercraft.
Do not follow directly behind water-
craft 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.
Remember watercraft and other boats do not have brakes. Do not release the throttle when trying to steer away from objects—you need throttle to steer.
Practice reboarding in shallow water
before riding in deep water.

Boarding and starting in deep water
WARNING
Operator and passenger should prac-
tice getting on board in shallow water before riding in deep water. Boarding in deep water requires more skill.
The fatigue and exposure that could
result after unsuccessful attempts to get back on the watercraft may increase the risk of injuries and drown­ing.
Boarding alone
1. Swim to the rear of the watercraft and place both hands on the boarding plat­form, pull yourself up, and then grasp the handgrip with one hand.
2. Pull yourself up to a kneeling position on the platform, and then move to the seat and sit astride.
3. Attach the engine shut-off cord to your wrist, and then install the clip to the engine shut-off switch.
4. Grip the handlebars firmly with both hands, place both feet in footwell, start the engine, and look in all directions before starting off.
WARNING
Before starting off, make sure that there are no boats, obstructions, or swimmers around you.
3-23
Page 75
EJU00737a
Boarding with a passenger
WARNING
Severe internal injuries can occur if water is forced into body cavities as a result of being near the jet thrust nozzle. Do not apply throttle until the passenger is seated with his or her feet on the floor of the footwell and is holding on to the operator.
1. Climb on board as noted in the previous section, and sit astride the seat. Attach the engine shut-off cord to your wrist, and then install the clip to the engine shut-off switch.
2. Have the passenger move to the rear of the watercraft.
3. Have the passenger get on board and sit on the seat.
NOTE:
When a passenger is getting on board, both the passenger and the operator should try to balance the watercraft.
4. The operator should check to see that the passenger has his or her feet on the floor of the footwell and that he or she is securely holding on to the operator.
5. Start the engine, look in all directions, and then accelerate to planing speed.
WARNING
Before starting off, make sure that there are no boats, obstructions, or swimmers around you.
3-24
Page 76
NOTE:
The heavier the total weight of the operator and passengers, the more difficult it will be to balance the watercraft. Do not operate the watercraft when the total weight exceeds 160 kg (353 lb) including any cargo. If it is difficult to balance the vehicle at a standstill, proceed as follows:
1. The passenger must steady the water­craft while the operator is boarding. The operator pulls himself up onto the plat­form into a seating position, then bal­ances the vehicle.
2. Attach the lanyard to your left wrist, then install the clip on the lanyard to the engine shut-off switch. Start the engine and keep it at idle.
3. The passenger pulls himself up on the platform, kneels down, then crawls onto the seat as the watercraft accelerates.
4. The watercraft can now be accelerated to planing speed, then the operator can reduce the throttle to the desired running speed.
EJU00677a
Capsized watercraft
If the watercraft capsizes, follow the pro­cedures below carefully to prevent damage or injury.
WARNING
IMPROPER UPRIGHTING CAN CAUSE INJURY:
Shut engine off, and be sure engine
shut-off cord is removed from the
engine shut-off switch.
Do not put hand in intake grate.
Watch so you are not hit by the water-
craft as it comes over.
3-25
Page 77
CAUTION:
Be sure to remove the clip from the shut­off switch, otherwise the engine will overheat and engine damage may occur.
1. Shut the engine off by removing the clip
from the engine shut-off switch.
2. Swim to the rear of the watercraft. Pull
the watercraft over with left hand on ride plate while pushing down on the gun­wale with your right hand/foot.
NOTE:
If the port side of the capsized watercraft is tilting upward, first tilt the watercraft so the port side is down by using your weight to press down on the rub rail.
CAUTION:
Do not turn the watercraft over counter­clockwise, otherwise water may leak into the carburetor and engine and cause damage.
3. Start the engine, and then head for
shore to inspect the engine for water damage.
CAUTION:
If the watercraft has been capsized for 5 minutes or more, air may have entered the oil injection system. Leave the engine off, or operate only at trolling speed, for 10 minutes after the watercraft has been turned right-side up. This will allow any air to bleed off.
3-26
Page 78
EJU00499
Turning the watercraft
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 is produced.
The amount of jet thrust, in addition to the
A
B
C
position of the handlebars, determines how sharply you turn. 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.
C. Releasing the throttle completely pro-
duces 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, but once the engine slows down, the watercraft will no longer respond to handlebar input until you apply throttle again or you reach a trolling speed. At trolling speed, the watercraft can be turned gradually by handlebar position 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.
You need throttle to steer.
D
3-27
Page 79
WARNING
Do not release the throttle 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 the watercraft to slide side-
ways or spin, throwing the operator
and passengers overboard which
could cause an injury.
3-28
Page 80
EJU00621
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 100 m (330 ft) after the throttle is released and 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.
WARNING
Allow adequate stopping distance.
Take early action to avoid collisions.
Remember, 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 slow-
ing down in case you need engine
power to steer away from a boat or
other obstacle that comes into your
path.
3-29
Page 81
EJU00635
Beaching the watercraft
1. Make sure no obstructions, boats or
swimmers are near the beach. Release the throttle lever about 100 m (330 ft) before you reach the intended beaching area.
2. Approach the beach slowly and stop the
engine before reaching land. Remem­ber: you need throttle to steer.
3. Get off the watercraft and pull it up on
the beach.
CAUTION:
Small pebbles, sand, seaweed, and other debris can be pulled into the jet intake and impair or damage the impeller. Always stop the engine and get off before beaching the watercraft.
EJU00505
Docking the watercraft
1. Make sure that no obstructions, boats or
swimmers are close to the watercraft. Reduce speed about 100 m (330 ft) away from the dock.
2. Slowly approach the dock and stop the
engine just before coming alongside it.
EJU00507
Rough water operation
The force of landing after jumping can cause a strong impact on both the watercraft and the operator and passengers. It is pos­sible for the operator to hit his or her chest or jaw on the watercraft body or handlebars and be injured. Do not operate the water­craft with your chin right above the handle­bars or with your feet outside the watercraft.
Operating in rough water or jumping waves can also crack the watercraft body or damage internal parts. Avoid operating in rough water or bad weather conditions.

EJU00691a
Post-operation checks
Always perform the following post-opera­tion checks after operating the watercraft.
1. Remove the watercraft from the water.
2. Wash down the hull, handlebars, and jet
unit with fresh water.
3. Remove the seat and check the engine
compartment for water.
To drain excess water, remove the stern drain plugs, then raise the bow of the water­craft enough to allow water in the bilge to drain out.
NOTE:
This watercraft is equipped with an auto­matic bilge-draining system that removes water from the engine compartment while you are underway. However, some residual water will remain.
4. Put the watercraft in a horizontal posi-
tion.
5. Flush the cooling system to prevent it
from clogging with salt, sand, or dirt. (See page 4-1 for flushing the cooling system procedures.)
6. Drain residual water from the exhaust
system by alternately squeezing and releasing the throttle lever for 10 to 15 seconds while the engine is running.
CAUTION:
Do not attempt to run the engine at full throttle or for more than 15 seconds while the watercraft is out of the water, otherwise the engine may overheat or seize.
3-31
Page 83
7. If the watercraft will be stored for a week
or more, lubricate internal engine com­ponents to help prevent corrosion. (See page 4-3 for lubrication procedures.)
8. Rinse the engine and engine compart-
ment with a small amount of water.
CAUTION:
Do not use high pressure when rinsing the engine or engine compartment as severe engine damage could result.
9. Wipe the engine and engine compart-
ment dry with a clean cloth (repeat step 3, if necessary).
10. Wipe the hull, handlebars, and jet unit
dry with a clean cloth.

Transporting
WARNING
Always place the fuel cock knob in the “OFF” position when transporting the watercraft, otherwise fuel could leak out into the engine or engine compartment, which would create a fire hazard.
When transporting the watercraft on a trailer, secure the tie downs to the trailer through the bow eye and stern rope holes.
CAUTION:
Do not route ropes or tie downs over
the seat, as they may leave permanent
marks on the seat’s surface. Also,
wrap the ropes or tie downs with tow-
els or rags where they touch the body
of the watercraft to avoid scratching or
damage.
Before putting the watercraft on the
trailer or transporting it, be sure to put
the shift lever in the forward position,
otherwise the reverse gate may hit an
obstruction, which may cause dam-
age.

EJU00552a
Cleaning and adjusting the spark plugs
The spark plug is an important engine component and is easy to inspect. The con­dition of the spark plug can indicate some­thing about the condition of the engine. For example, if the center electrode porcelain is very white, this could indicate an intake air leak or carburetion problem in that cylinder. Do not attempt to diagnose any problems yourself. Have a Yamaha dealer service the watercraft.
Remove and inspect the spark plug peri­odically; heat and deposits will cause the spark plug to slowly break down and erode. If electrode erosion becomes excessive, or if carbon and other deposits are excessive, replace the spark plug with the specified plug.
Standard spark plug:
BR8HS
Measure the spark plug gap a with a wire thickness gauge before installing the spark plug. Adjust the gap to specification if necessary.
Spark plug gap:
0.6–0.7 mm (0.024–0.028 in)
To reinstall spark plug:
1. Clean the gasket surface.
2. Wipe any dirt from the threads of the
spark plug.
3. Screw the spark plug to the correct
torque.
Spark plug torque:
25 Nm (2.5 m·kg, 18 ft·lb)
4-14
Page 100
NOTE:
Wipe off any water on the spark plug or
inside the cap before installing the spark
plug cap. Push the spark plug cap down
until it clicks.
If a torque wrench is not available when
you are fitting a new spark plug, a good
estimate of the correct torque is 1/4 turn
to 1/2 turn past finger tight. Have the
spark plug adjusted to the correct torque
with a torque wrench as soon as possible.
WARNING
Be careful not to damage the insulator when removing or installing a spark plug. A damaged insulator could allow sparks to escape, which could lead to explosion or fire.
