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, bylaws 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.

EJU10000

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.

1-9

E

EJU10010

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

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.

EJU10020

Operation requirements

All riders must wear an authority-

●

approved 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
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.

E

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

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 3-6
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.

E

1-12

E

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 1-16.)

EJU13820

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.
Visual distress signals

●

It is recommended that an authority­approved pyrotechnic device be stored in
a waterproof container on your watercraft.
A mirror can also be used as an emer­gency signal. Contact your Yamaha
dealer for more information.
Watch

●

A watch is helpful so you will know how
long you have been operating.
Towline

●

A towline can be used to tow a disabled
watercraft in an emergency.

1-13

E

EJU20020

Hazard information

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.

Do not start engine on land until everyone

●

is away from stern. Hot water and steam

spurting from exhaust outlet can cause

serious burns.

Hot muffler surfaces can cause serious

●

burns. Do not touch any muffler surface

during or after engine operation. Catalytic

converter gets hotter after engine stops.

EJU20030

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. This model has the Yamaha
Engine Management System (YEMS)
that includes an Off-Throttle Steering
(OTS) system. It will activate at planing
speeds should you attempt to steer the
watercraft after releasing the throttle lever.
The OTS system assists in turning by
continuing to supply some thrust while the
watercraft is decelerating, but you can
turn more sharply if you apply throttle
while turning the handlebars. The OTS
system does not function below planing
speeds or when the engine is off. Once
the engine slows down, the watercraft will
no longer turn in response to handlebar
input until you apply throttle again or you
reach trolling speed. Practice turning in
an open area without obstructions 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.

1-14

Keep away from the 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.

EJU10050

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.

EJU10060

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.

Cooling water pilot outlet

This watercraft is equipped with cooling

water pilot outlets.

When the engine is running, cooling

water is circulated in the engine, and then it
is discharged from the pilot outlets.

To check for proper operation of the cool-

ing system, check that water is being dis­charged from the pilot outlets. If water is not
being discharged from the outlets, cooling
water may not be circulating in the engine.
When this occurs, stop the engine and
check for the cause. (See pages 2-12 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.

@

2-8

E

EJU19950

Steering system

Your watercraft can be steered by turning

the handlebars 1 in the 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
degree of a turn, throttle must always be
applied when attempting a turn, except at
trolling speed.

This model has the Yamaha Engine Man-

agement System (YEMS) that includes an
Off-Throttle Steering (OTS) system. It will
activate at planing speeds should you
attempt to steer the watercraft after releas­ing the throttle lever. The OTS system
assists in turning by continuing to supply
some thrust while the watercraft is deceler­ating, but you can turn more sharply if you
apply throttle while turning the handlebars.
The OTS system does not function below
planing speeds or when the engine is off.
Once the engine slows down, the watercraft
will no longer turn in response to handlebar
input until you apply throttle again or you
reach trolling speed.

2-9

E

CAUTION:

EJU10220

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.

@

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.

2-10

E

EJU10230

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.

EJU10240

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.

EJU19790

Handgrip

The handgrip 1 provides a handhold for
boarding the watercraft.

WARNING

@

Do not use the handgrip to lift the water­craft. The watercraft could fall, which
could result in severe injury.

@

2-11

E

CAUTION:

EJU20450

Engine overheat warning
system

This model is equipped with an engine
overheat warning system.

If the engine starts to overheat, the warn­ing light and the engine overheat warning
indicator begin to blink, and the buzzer
sounds intermittently.

When this occurs, reduce the engine
speed and beach the watercraft. Check for
water discharge. If there is no discharge of
water at the cooling water pilot outlet, whole
the engine is running, 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.

@

@

This watercraft is equipped with a cata­lytic converter.

Return to shore at low speed if over-

●

heat warning indicator and buzzer

come on. If you ignore these signals,

engine will stop running and cannot be

restarted until exhaust system cools

down.

Have your watercraft inspected and

●

serviced by a Yamaha dealer if engine

stops due to overheating.

@

2-12

E

If the overheat warning is ignored, engine
and exhaust system heat may increase, par­ticularly if the watercraft is operated at
higher speeds. When this occurs, the warn­ing light, the engine overheat warning indi­cator and the buzzer will change from
intermittently to continuously on, and the
overheat system will stop ignition to the
engine to reduce the risk of severe over­heating. The engine cannot be started until
it cools down, so it may be necessary to
have the watercraft towed back to the
beach. (See “Towing the watercraft” on page

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.

The engine utilizes an electronic fuel
injection system to deliver the optimal air­fuel mixture ratio required by the engine.
With optimal combustion conditions, this
system is able to increase startability and
improve fuel economy.

EJU10690

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 1-15. 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.

EJU10700

Learning to operate your
watercraft

Before operating the watercraft, always
perform the pre-operation checks listed on
page 3-6. 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.

3-21

E

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.

EJU10710

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.

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.

Starting the watercraft

WARNING

@

Scan constantly for people, objects,

●

and other watercraft. Be alert for con-

ditions 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 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 sub-

merged 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 drown-

ing.

EJU10770

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.

@

3-26

E

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 watercraft at a stand­still, proceed as follows:

1. The passenger must steady the water-

craft while the operator is boarding. The
operator pulls himself up onto the plat­form into a seating position, then bal­ances the watercraft.

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.

@

To efficiently discharge water from the
engine compartment, operate the watercraft
as straight as possible and above planing
speed for at least 2 minutes.

@

@

Do not operate the engine at full throttle
for at least one minute after the engine
has been restarted. Excessive water in
the bilge can splash into the engine,
which can result in severe damage.

@

3-28

EJU19960

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 produced.

The amount of jet thrust, in addition to the
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 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
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.

3-29

E

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 the watercraft to slide side-

ways or spin, throwing the operator

and passengers overboard which

could cause an injury.

@

This model has the Yamaha Engine Man­agement System (YEMS) that includes an
Off-Throttle Steering (OTS) system. It will
activate at planing speeds should you
attempt to steer the watercraft after releas­ing the throttle lever (see condition C
above). The OTS system assists in turning
by continuing to supply some thrust while
the watercraft is decelerating, but you can
turn more sharply if you apply throttle while
turning the handlebars. The OTS system
does not function below planing speeds or
when the engine is off. Once the engine
slows down, the watercraft will no longer
turn in response to handlebar input until you
apply throttle again or you reach trolling
speed.

3-30

E

EJU10800

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
125 m (410 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.

CAUTION:

EJU10810

Beaching the watercraft

1. Make sure no obstructions, boats or

swimmers are near the beach. Release
the throttle lever about 125 m (410 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.

@

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.

@

EJU10820

Docking the watercraft

1. Make sure that no obstructions, boats or

swimmers are close to the watercraft.
Reduce speed about 125 m (410 ft)
away from the dock.

2. Slowly approach the dock and stop the

engine just before coming alongside it.

EJU10830

Rough water operation

The force of landing after jumping can
cause a strong impact on both the watercraft
and the operator and passenger. 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.

Inspecting the fuel system

WARNING

@

Gasoline is highly flammable and explo­sive. Failure to check for and repair any
fuel leakage could result in fire or explo­sion. A fire or explosion can cause
severe injury or death. Shut off the
engine. Do not smoke. Avoid spilling
gasoline.
Fuel in hose is pressurized.
Fuel can spray out and cause injury or a
fire hazard if fuel line is disconnected.
Do not attempt to run engine with fuel
line disconnected.

@

Check the fuel system for leaks, cracks,
or malfunctions. If any problem is found,
consult a Yamaha dealer.

Check:

Fuel tank for water or dirt.

●

Fuel tank cap (seal) for damage.

●

Fuel tank for damage, cracks or leakage.

●

Fuel hose joint for leakage.

●

Fuel hose for cracks or other damage.

●

Air bleeding passages for leakage.

●

Inspecting the jet thrust nozzle
angle

Check for smooth operation of the handle­bars and jet thrust nozzle.

Turn the handlebars as far as possible to
the right and left and check that the differ­ence of distance A and B between the jet
thrust nozzle and the nozzle is within 5 mm.

Difference of A and B:

Maximum 5 mm (0.20 in)

If steering is stiff or misadjusted, have a
Yamaha dealer service it.

Inspecting and adjusting the
throttle cable

Check that the throttle cable moves back
to the set position smoothly and that free
play is within specification.

1. Squeeze and release the throttle lever. If

the lever does not return smoothly, have
a Yamaha dealer service it.

2. Adjust free play a by loosening the lock-

nut 1 and turning the adjuster 2.

Throttle lever free play:

4–7 mm (0.16–0.28 in)

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 plugs peri­odically; heat and deposits will cause the
spark plugs 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: BR8ES-11

Measure the spark plug gap a with a
wire thickness gauge. Replace the spark
plugs or adjust the gap to specification if
necessary.

Spark plug gap:

1.0–1.1 mm (0.039–0.043 in)

To install the spark plug:

1. Clean the gasket surface.

2. Wipe any dirt from the threads of the

spark plug.

3. Install the spark plug, and then tighten it

to the specified torque.

Spark plug tightening torque:

25 N·m (2.5 kgf·m, 18 ft·lb)

4. Install the spark plug cap.

4-13

E

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 is securely installed.

If a torque wrench is not available when

●

you are installing a new spark plug, a

good estimate of the correct torque is 1/4

turn to 1/2 turn past finger tight with the

spark plug wrench included in the tool kit.

Have the spark plug adjusted to the cor-

rect 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 an explo­sion or fire.
