SCHEDULED MAINTENANCE CHECKS AND SERVICES

Scheduled Maintenance Checks and Services
Frequency and Scheduled Maintenance
Proper care, maintenance and adjustment will contribute to the peak performance of the boat, while also
extending the overall service life and the resale value.
Most MasterCraft boats built over the past decade are equipped with Indmar engines, and the information that
follows was developed with their assistance. The instructions are grouped by the required service intervals. The
pages that follow also provide instructions on how to accomplish the required checks, inspections and services
listed. Your MasterCraft dealer or service center is the best source for proper maintenance.
The following definitions apply to maintenance:
Check: Verify the operational readiness by physical measurement, i.e., measuring the oil level with the dipstick
gauge, or alignment with a feeler gauge.
Inspect: Determine the operational readiness by examination, i.e., by sight, sound or feel.
Change: Tasks required periodically to keep the boat in proper operating condition, i.e., drain, replenish
or service.
New Boat Break-In
Note: MasterCraft recommends these functions be performed by factory-trained MasterCraft
technicians.
• Change the engine oil and filter after the initial 10 and 50 hour mark of operation. Use only manufacturers’
recommended lubricants. (See Quarterly and Annual Maintenance also.)
• Lubricate the engine starter drive gear and shaft. (See Quarterly Maintenance also.)
• Check the alignment of the propeller shaft. (See Annual Maintenance also.)
• Have your dealer change the fuel filter after the first 50 hours of operations, and then again at 100 hours. The
fuel filter should be changed annually if less than 100 hours are run during the previous season.
Before Each Use
Before the engine has been started:
• Inspect the intake water strainer for blockage. If there is blockage, check the transmission cooler also.
• Check the cooling system level (fresh water cooling-equipped boats only).
• Check the alternator belt for looseness or damage.
• Inspect the battery connections and hold-downs.
• Inspect the drive train for loose or missing hardware.
• Inspect the throttle and shift cables for kinks, wear and interference with other components.
• Inspect the raw water impel-
ler if the boat showed signs
of overheating during the last
operation.
• Inspect the propeller shaft log
for excessive water entry.
• Inspect the fuel system lines
and connections for leakage.
• Inspect the exhaust system
for leaks.
As you start the engine:
• Check that the voltage regis-
ters a fully charged battery.
