Preface
This manual has been prepared by Yamaha primarily for use by Yamaha dealers and their trained mechanics when performing maintenance procedures and repairs to Yamaha equipment. It has been written to suit the needs of persons who have the Bronze Technical Certificate of the YTA (Yamaha
Technical Academy) marine or the equivalent basic understanding of the mechanical and electrical
concepts and procedures inherent in the work, for without such knowledge attempted repairs or service
to the equipment could render it unsafe or unfit for use.
Because Yamaha has a policy of continuously improving its products, models may differ in detail from
the descriptions and illustrations given in this publication. Use only the latest edition of this manual. Authorized Yamaha dealers are notified periodically of modifications and significant changes in specifications and procedures, and these are incorporated in successive editions of this manual. Also, up-todate parts information is available on YPEC-web. Additional information and up-to-date information on
Yamaha products and services are available on Yamaha Service Portal.
Important information
Particularly important information is distinguished in this manual by the following notations:
The Safety Alert Symbol means ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
A WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.
A NOTICE indicates special precautions that must be taken to avoid damage to the watercraft
or other property.
TIP:
A TIP provides key information to make procedures easier or clearer.

Safety while working
1-1
Safety while working
To prevent an accident or injury and to provide
quality service, observe the following safety
procedures.
Rotating parts
Hands, feet, hair, jewelry, clothing, personal
flotation device straps, and so on, can become
entangled with internal rotating parts of the engine or jet pump unit, resulting in serious injury
or death.
• Keep hands, feet, hair, jewelry, clothing, personal flotation device straps, and so on,
away from any exposed moving parts when
operating the engine with the seat removed.
• Keep away from intake grate while engine is
on.
Hot parts
During and after operation, engine parts are
hot enough to cause burns. Do not touch any
parts in the engine compartment until the engine has cooled.
Electric shock
Do not touch any electrical parts while starting
or operating the engine. Otherwise, shock or
electrocution could result.
Impeller
Do not hold the impeller with your hands when
loosening or tightening the impeller.
Handling of gasoline
• Gasoline is highly flammable. Keep gasoline
and all flammable products away from heat,
sparks, and open flames.
• Gasoline is poisonous and can cause injury
or death. Handle gasoline with care. Never
siphon gasoline by mouth. If you 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.
Ventilation
• Gasoline vapor and exhaust gas are heavier
than air and extremely poisonous. If gasoline
vapor or exhaust gas is inhaled in large
quantities, it may cause loss of consciousness and death within a short time.
• When test running an engine indoors (for example, in a water tank) make sure to do so
where adequate ventilation can be maintained.
Self-protection
• Protect your eyes by wearing safety glasses
or safety goggles during all operations involving drilling and grinding, or when using an air
compressor.
1-2
Safety while working
• Protect your hands and feet by wearing protective gloves and safety shoes when necessary.
Working with crane
• When moving the watercraft, or when lifting
the engine during removal or installation,
make sure to use a crane with a lifting capacity that is equal to or more than the weight of
the watercraft or engine respectively.
• When lifting the watercraft, use the watercraft
lift harness and make sure that the watercraft
is in a stable position when moving it.
• Use the wire ropes of adequate strength, and
lift up the engine unit using the three point
suspension.
• If the engine unit does not have three or more
points to be suspended, support it using additional ropes or the like so that the engine
unit can be lifted and carried in a stable manner.
Handling of heat gun
• Improper handling of a heat gun may result in
burns. For information on the proper handling
of the heat gun, see the operation manual issued by the manufacturer.
• When using a heat gun, keep it away from
the gasoline and oil, to prevent a fire.
• Components become hot enough to cause
burns. Do not touch any hot components directly.
Parts, lubricants, and sealants
Use only genuine Yamaha parts, lubricants,
and sealants, or those recommended by Yamaha, when servicing or repairing the watercraft.
Safety while working
1-3
Handling of sealants
• Wear protective gloves to protect your skin,
when using the sealants.
• See the material safety data sheet issued by
the manufacturer. Some of the sealants may
be harmful to human health.
Special service tool
Use the recommended special service tools to
work safely, and to protect parts from damage.
Tightening torque
Follow the tightening torque specifications provided throughout the manual. When tightening
nuts, bolts, and screws, tighten the large sizes
first, and tighten fasteners starting in the center
and moving outward.
Non-reusable parts
Always use new gaskets, seals, O-rings, cotter
pins, and so on, when installing or assembling
parts.
Disassembly and assembly
• Use compressed air to remove dust and dirt
during disassembly.
• Apply engine oil to the contact surfaces of
moving parts before assembly.
• Install bearings so that the bearing identification mark is facing in the direction indicated in
the installation procedure. In addition, make
sure to lubricate the bearings liberally.
• Apply a thin coat of water resistant grease to
the lip and periphery of an oil seal before installation.
• Check that moving parts operate normally after assembly.

General feature
The F2W features a hull and deck that are based on those of the F2X and is equipped with an 1812
cm³ engine.
While retaining the stability and comfort of the F2X, the acceleration performance and maximum speed
have been improved by increasing the output of the engine.
The 6EW engine is based on the 6CN engine and the size and weight of the fuse box have been reduced.

RiDE system
Unlike previous systems with mechanical shifting and Q.S.T.S., the RiDE motor is driven through electric signals in order to conduct shifting and trim operations.
With electrical operation, conventional cables are not used. By using the RiDE lever and electric trim
switch unit incorporated into the left handlebar switch, shifting and trim operations are easy to control.
The number of parts has been reduced, and serviceability has improved.
The trim function drives the RiDE motor through the electric trim switch in order to move the nozzle.
The trim position is sent to the ECM in order to display the trim angle on the multifunction meter.
The shift function transfers the RiDE lever opening angle into electric signals and then delivers the signals to the ECM. The ECM controls the engine based on the RiDE lever signals, shift position, and engine status, and sends a shift request to the RiDE motor.
When changing the shift, the reverse gate operates after the engine speed has dropped and the water
jet stream intensity has been reduced. This reduces the strain on the reverse gate and allows for
smooth shifting.

Technical tips
RiDE motor
The RiDE lever employs the same part used for the throttle lever that incorporates the APS. An RPS
(RiDE position sensor) is built into the RiDE lever.
The RiDE motor is an assembly part that includes the shift motor and trim motor, a shift position sensor
that detects the position of each motor, the trim position sensor, and a built-in SCU to control each motor.
This system has sensors, and also has a fail-safe function.
The ECM and SCU use CAN to deliver shift request, shift position, and trim position information.

ETV system
The F2W is equipped with the same throttle lever as that of the F2S.
The throttle lever has an APS which senses the degree of throttle opening and converts the status into
electronic signals, delivering the information to the ECM. The ECM controls the ETV based on the input
signals of the APS.
Employing the APS in the throttle lever has eliminated the need for throttle cables, reducing the number
of parts used, thereby improving throttle response and serviceability.
The throttle lever has 2 sensors as per the previous APS, the APS 1 and APS 2, which mutually diagnose any failures each system may encounter.
The APS full-close switch detects the fully closed throttle lever position.
