All of the procedures in this manual are organized in a sequential, step-by-step format. The information has been compiled to provide the mechanic with an easy to read, handy reference that contains comprehensive explanations of all disassembly, repair, assembly, and inspection operations.

In this revised format, the condition of a faulty component will precede an arrow symbol and the course of action required will follow the symbol, e.g.,

Bearings

Pitting/scratches → Replace.

To assist you in finding your way through this manual, the section title and major heading is given at the top of every page.

ILLUSTRATIONS

The illustrations within this service manual represent all of the designated models.

CROSS REFERENCES

The cross references have been kept to a minimum. Cross references will direct you to the appropriate section or chapter.

E

IMPORTANT INFORMATION

In this Service Manual particularly important information is distinguished in the following ways.

The Safety Alert Symbol means ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!

WARNING

Failure to follow WARNING instructions could result in severe injury or death to the machine operator, a bystander, or a person inspecting or repairing the water vehicle.

CAUTION:

A CAUTION indicates special precautions that must be taken to avoid damage to the water vehicle.

NOTE:

A NOTE provides key information to make procedures easier or clearer.

IMPORTANT:

This part has been subjected to change of specification during production.

HOW TO USE THIS MANUAL

1To help identify parts and clarify procedure steps, there are exploded diagrams at the start of each removal and disassembly section.

2 Numbers are given in the order of the jobs in the exploded diagram.

3 Symbols indicate parts to be lubricated or replaced (see “SYMBOLS”).

4A job instruction chart accompanies the exploded diagram, providing the order of jobs, names of parts, notes in jobs, etc.

5Dimension figures and the number of parts, are provided for fasteners that require a tightening torque.

Example:

GEN INFO

SAFETY WHILE WORKING

E

SAFETY WHILE WORKING

The procedures given in this manual are those recommended by Yamaha to be followed by Yamaha dealers and their mechanics.

FIRE PREVENTION

Gasoline (petrol) is highly flammable. Petroleum vapor is explosive if ignited.

Do not smoke while handling gasoline (petrol) and keep it away from heat, sparks, and open flames.

VENTILATION

Petroleum vapor is heavier than air and is deadly if inhaled in large quantities. Engine exhaust gases are harmful to breathe. When test-running an engine indoors, maintain good ventilation.

SELF-PROTECTION

Protect your eyes with suitable safety spectacles or safety goggles when grinding or doing any operation which may cause particles to fly off.

Protect hands and feet by wearing safety gloves or protective shoes if appropriate to the work you are doing.

OILS, GREASES AND SEALING FLUIDS

Use only genuine Yamaha oils, greases, and sealing fluids or those recommended by Yamaha.

1-2

GEN INFO

SAFETY WHILE WORKING

E

Under normal conditions of use there should be no hazards from the use of the lubricants mentioned in this manual, but safety is all-important, and by adopting good safety practises any risk is minimized. A summary of the most important precautions is as follows:

1.While working, maintain good standards of personal and industrial hygiene.

2.Clothing which has become contaminated with lubricants should be changed as soon as practicable and laundered before further use.

3.Avoid skin contact with lubricants (e.g., do not place a soiled rag in your pocket).

4.Hands and any other part of the body which have been in contact with lubricants or lubricant-contaminated clothing should be thoroughly washed with hot water and soap as soon as practicable.

5.To protect the skin, the application of a suitable barrier cream to the hands before working is recommended.

6.A supply of clean lint-free cloths should be available for wiping purposes.

GOOD WORKING PRACTICES

1.The right tools

Use the recommended special tools to protect parts from damage. Use the right tool in the right manner – do not improvise.

2.Tightening torque

Follow the tightening torque instructions. When tightening bolts, nuts and screws, tighten the larger sizes first and tighten inner-positioned fixings before outer-positioned ones.

1-3

GEN INFO

SAFETY WHILE WORKING

E

3.Non-reusable items

Always use new gaskets, packings, O- rings, oil seals, split-pins, circlips, etc., on reassembly.

DISASSEMBLY AND ASSEMBLY

1.Clean parts with compressed air when disassembling.

2.Oil the contact surfaces of moving parts during assembly.

3.After assembly, check that moving parts operate normally.

4.Install bearings with the manufacturer’s markings on the side exposed to view and liberally oil the bearings.

CAUTION:

Do not spin bearings with compressed air because this will damage their surfaces.

5.When installing oil seals, apply a light coat of water-resistant grease to the outside diameter.

Using the correct special tools recommended by Yamaha, will aid the work and enable accurate assembly and tune-up. Improvisations and using improper tools can damage the equipment.

NOTE:

For U.S.A. and Canada, use part numbers starting with “J-”, “YB-”, “YM-”, “YU-” or “YW-”.

For other countries, use part numbers starting with “90890-”.

GENERAL TORQUE

This chart specifies tightening torques for standard fasteners with a standard ISO thread pitch. Tightening torque specifications for special components or assemblies are provided in applicable sections of this manual. To avoid warpage, tighten multifastener assemblies in a crisscross fashion and progressive stages until the specified tightening torque is reached. Unless otherwise specified, tightening torque specifications require clean, dry threads.

Components should be at room temperature.

Steering column inspection

1.Inspect:

Steering column

Excessive play → Replace the steering column.

Refer to “STEERING COLUMN” in chapter 8.

Inspection steps:

Move the handlebar up and down and back and forth.

Check the excessive play of the handlebar.

Steering cable inspection and adjustment

1. Inspect:

Distance a, b

Out of specification → Adjust.

 

 

 

 

 

 

 

 

 

 

Inspection steps:

 

 

 

 

Turn the handlebar from lock to lock.

 

 

 

 

Measure distances a and b.

 

 

 

 

If the difference is not within specifica-

 

 

 

 

tion, adjust the cable joint.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Difference of distances a and b:

 

 

 

 

Maximum 5 mm (0.2 in)

 

 

 

 

 

 

 

 

 

 

2. Adjust:

 

 

 

 

 

 

 

 

 

 

Steering cable joint

 

 

 

 

(steering column side)

 

 

 

 

 

 

 

 

 

 

Adjustment steps:

 

 

 

 

Loosen the locknut 1.

 

 

 

 

Disconnect the steering cable joint 2

 

 

 

 

from the ball joint 3.

 

 

 

 

Turn the cable joint in or out for adjust-

 

 

 

 

ing the distances a and b.

 

 

 

 

 

 

 

 

 

 

Turn in

Distance a is increased.

 

 

 

 

 

 

 

 

 

2

 

 

Turn out

Distance b is increased.
