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 compen-
sate 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!
ANNUALLY (Every 100 Hours)
MasterCraft recommends that your annual–or 100-hour–maintenance
requirements be performed by your MasterCraft dealer. The staff there has
the proper equipment and technical training to best meet your service needs.
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.
Even if you plan to have annual maintenance work completed by your MasterCraft service technician, you still should
review this section and ensure that you have some understanding of what is necessary to keep your boat in top condition.
