GENERAL
Some carburetor components and / or settings
can be changed to improve boat performance in
high altitude regions between 1500-3000 m
(5000-10000 ft).
Refer to the service department for the latest
specifications.
CAUTION : Such modifications should
only be performed by experience me-
chanics since they can greatly affect boat per-
formance.

er may be harmful to the rubber parts, O-
ring, etc. Therefore, it is recommended to re-
move those parts prior to cleaning.
