SCHEDULED
FREQUENCY AND
SCHEDULED MAINTENANCE
Proper care, maintenance and adjustment will contrib-
ute 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 instruc-
tions 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 mea-
surement, i.e., measuring the oil level with the dipstick
gauge, or alignment with a feeler gauge.
Inspect: Determine the operational readiness by examina-
tion, 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 impeller 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 registers a fully charged battery.
After running the engine at least five minutes:
• Check the transmission fluid level.
• Check the engine oil level.
QUARTERLY (EVERY 50 HOURS)
Note: MasterCraft recommends that these functions
be performed by factory-trained MasterCraft technicians.
Before the engine has been started or after it has cooled:
• Lubricate the engine starter gear and shaft.
• Check the safety equipment.
After the engine has run at least three minutes:
• Change the engine oil and filter.
ANNUALLY (EVERY 100 HOURS)
Note: MasterCraft recommends that these functions be
performed by factory-trained MasterCraft technicians.
Before the engine has been started or after it has cooled:
• Clean the engine flame arrestor.
• Replace the fuel filter (trained technician-only function
due to pressure in-line).
• Perform an engine tune-up.
• Replace the raw water impeller.
• Replace the ballast pump impeller.
• Check the propeller shaft coupler alignment.
• Lubricate the steering system.
• Lubricate the throttle and shift cables.
• Check the engine mounts.
• Inspect the complete fuel system for leakage.
After the engine has run at least five minutes:
• Change the engine oil and filter.
