Frequency and Scheduled Maintenance
Proper care, maintenance and adjustment will contribute to the peak performance of the Mas-
terCraft boat, while also extending the overall service life and the resale value.
The pages that follow provide instructions on how to accomplish the required checks, inspections
and services listed. An authorized MasterCraft service department is the best source for proper main-
tenance.
Note: The engine and drive train require scheduled maintenance checks and services in addi-
tion to the boat’s other maintenance requirements. Read and understand the engine owner’s
manual that has been provided, and follow the maintenance schedule to ensure proper opera-
tion and quality service over the life of the boat and drive train. Failure to follow the mainte-
nance requirements and instructions listed in this and all other manuals may result in damage
to the components, systems and equipment of the boat, which resulting damage would not be
covered by warranty! Safety issues are also directly impacted by proper maintenance!
