NOTICE

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 a 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.

INFO SAFETY WHILE WORKING

SAFETY WHILE WORKING

To prevent and accident or injury and to

ensure quality service, follow the safety proce-

dures provided below.

FIRE PREVENTION

Gasoline is highly flammable.

Keep gasoline and all flammable products

away from heat, sparks, and open flames.

VENTILATION

Gasoline vapor and exhaust gas are heavier

than air and extremely poisonous. If inhaled in

large quantities they may cause loss of con-

sciousness and death within a short time.

When test running an engine indoors (e.g., in a

water tank), be sure to do so where adequate

ventilation can be maintained.

SELF-PROTECTION

Protect your eyes by wearing safety glasses or

safety goggles during all operation involving

drilling and grinding, or when using an air com-

pressor.

Protect your hands and feet by wearing protec-

tive gloves or safety shoes when necessary.

PARTS, LUBRICANTS, AND

SEALANTS

Use only genuine Yamaha parts, lubricants,

and sealants or those recommended by

Yamaha, when servicing or repairing the

watercraft.
