Annually
(Every One Hundred [100] Hours)
MasterCraft recommends that your annual—or one
hundred (100) hour—maintenance requirements be per-
formed by an authorized MasterCraft dealer. The sta
there has the proper equipment and technical training
to best meet your service needs.
Annual Maintenance
Some boat owners choose to personally execute
some maintenance procedures on their boats. Master-
Craft has provided information on several procedures.
For safety reasons, a few must be performed by au-
thorizedMasterCraftservicetechniciansonly,suchas

which is under pressure.

sis,atone hundred (100) hours or annually,whichever

sonal preparation and winterization (see Storage and
Winterization section for additional details). All of these
issues are extremely important to continued boating
pleasure, as well as long life for the boat, and the critical
