Important Information - Yamaha F150B Service Manual

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 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 ser-
vice 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-to-date parts information is available on YPEC-web. Additional information and up-
to-date information on Yamaha product and services are available on Service Portal.
