FREQUENCY AND SCHEDULED 
MAINTENANCE
Proper care, maintenance and adjustment will contribute to the 
peak performance of the MasterCraft 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 
maintenance.
NOTE: The engine and drive train require scheduled maintenance 
checks and services in addition 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 operation and quality service over the life of the boat 
and drive train. Failure to follow the maintenance requirements 
and instructions listed in this and all other manuals may result in 
damage to the components, systems and equipment of the boat. 
Resulting damage will not be covered by warranty. Safety issues 
are also directly impacted by proper maintenance!

performed by authorized MasterCraft technicians at an authorized 
MasterCraft dealer.
Check the alignment of the propeller shaft. (See Annual 
Maintenance also.)
Have an authorized MasterCraft service department change 
the fuel filter after the first fifty (50) hours of operation, and 
then again at one hundred (100) hours. The fuel filter should be 
changed annually, even if less than one hundred (100) hours are 
run during the previous season.
