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 techni-
cians.
• Change the engine oil and filter after the initial 10
and 50 hour mark of operation. Use only manufactur-
ers’ 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 cool-
ing-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 impeller if the boat showed
signs of overheating during the last operation.
