Maintenance 
Periodic checks and lubrication will keep your
watercraft in the safest and most efficient con-
dition possible. Therefore, make sure to carry
out the periodic maintenance. Safety is an ob-
ligation of the watercraft owner. Proper main-
tenance must be carried out to keep the
exhaust emission and sound levels within the
regulated limits. The most important points of
watercraft inspection and lubrication are ex-
plained on the following pages.
See a Yamaha dealer for genuine Yamaha re-
placement parts and optional accessories de-
signed for your watercraft.
Remember, failures that are the result of the
installation of parts or accessories which are
not qualitatively equivalent to genuine
Yamaha parts are not covered by the limited
warranty.
Maintenance, replacement, or repair of the
emission control devices and system may
be performed by any marine SI engine re-
pair establishment or individual. Warranty
repair, however, must be performed at an
authorized Yamaha marine dealership.
