Step 9:
The first time 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 additive levels than typical gasoline engine oils to com-
pensate 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 re-
quirements 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 infor-
mation 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 ad
-
ditional 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.
Clean the Engine Flame Arrestor
MasterCraft recommends that you have the flame arrestor inspected and cleaned by your dealer immediately prior
to starting the boating season. This procedure is extremely important and should be performed at least once a year.
There may be instances in which you need to check this yourself. If you have had evidence of material collect-
ing inside the flame arrestor in the past, you should check yours more often than annually, particularly after the boat
has been sitting for an extended period of time. The flame arrestor serves as a trap for airborne materials that might
otherwise enter the engine and cause damage. However, if your boat sits for a while, small creatures may crawl inside
and build a nest.
Be very careful while removing and while the flame arrestor is off the engine that absolutely nothing foreign
enters the engine through the area normally covered by the flame arrestor. Any materials entering can cause damage
to your engine and will void your warranty.
Because this process should be completed while the engine is cool and cannot burn your skin, we recommend
this be done before starting the boat.
