This manual was written by the Yamaha Motor
Company primarily for use by Yamaha dealers
and their qualified mechanics. It is not possible
to put an entire mechanic’s education into one
manual, so it is assumed that persons using this
book to perform maintenance and repairs on
Yamaha snowmobiles have a basic under-

such knowledge, attempted repairs or service

Yamaha Motor Company, Ltd. is continually
striving to improve all models manufactured by
Yamaha. Modifications and significant changes
in specifications or procedures will be for-
warded to all authorized Yamaha dealers and
will, where applicable, appear in future editions
of this manual.
