Step 6: The oil filter should be changed each time the oil is
changed. Remove the oil filter and dispose of it properly
on-shore.
Step 7: Fill a new MasterCraft oil filter about half full with
clean engine oil. Lightly lubricate the oil filter gasket and spin
the filter on until the gasket makes contact. Hand tighten the
filter one-quarter to one-half turn after contact. DO NOT use a
filter wrench to tighten.
Step 8: Re-attach the oil drain plug to the end of the hose
and refill the crankcase through the oil cap opening on the
valve cover. Check the oil level with the dipstick. If this is the
initial quarterly oil change, re-attach a cable tie around the oil
drain hose and the water line on the port side of the engine
as it came from the factory, to keep the line from coming in
contact with any hot areas.
Step 9: The first time that you re-start the engine when it
is back in the water, check the area around the filter for
any leaks.
Step 10: Stop the engine and re-check the oil level. Add more
oil if necessary.
Note: The engine oil recommendation for all engines is
SAE 15W40 oil, rated at SJ/CH4. This rating requires oils
to have higher additives levels than typical gasoline engine
oils to compensate for potential thinning or fuel dilution.
Any other rating other than SJ/CH4 may result in damage
or excessive wear to the engine and should be avoided!
Failure to follow the engine oil recommendation listed in the manual
can cause additional engine wear and increase the possibility of engine
component failure. Damage to your engine due to incorrect oil usage can
be costly to repair, and is not covered by your warranty!

ANNUAL MAINTENANCE
Some boat owners choose to execute some maintenance procedures on their
boats. We have provided information on several procedures. For safety reasons, a
few must be performed by MasterCraft service technicians only, such as anything
involving checks and repairs on the fuel line, which is under pressure.
Regardless of whether you choose to do some of the maintenance work yourself or have it completed by a technician, these
matters must be addressed on a regular basis, at 100 hours or annually, whichever comes first.
These procedures are in addition to seasonal preparation and winterization (see Winterization section for additional details).
All of these issues are extremely important to your continued boating pleasure, as well as long life for your boat and the critical
matter of safety.
