First Ten Hours
of Operation
Operations during the initial ten hours of
break-in is very much the same during the
second fi ve hours as the fi rst fi ve, except that
it is permissible to run at full speed for 2-3
minutes at a time. Do not accelerate suddenly
from low-to-full speed. Increase speed gradu-
ally during this period. Again, an occasional
cool-down period is recommended.
After the First 10 Hours
of Operation
Return the boat to your MasterCraft deal-
er for the 10-hour inspection. At this time,
your service technician should change the
engine oil and filter, as well as making oth-
er necessary checks, adjustments and ser-
vices.
The oil change is particularly
critical to long life and good service
from your engine!
After Break-In
Once the break-in period is over, the boat may be operated continuously at any speed, but not beyond the
maximum. For the RPT-1 engine that is 4800 RPMs; the MCX is 5200 RPMs, the LQ9 Cadillac is 5400 RPMs, and the
8.1 Liter engine is 5400 RPMs as well.
(Please refer to the Crusader operation manual for information and details on
proper break-in procedure for those engines.)
MasterCraft boat engines are equipped with rev-limiters which will cause a fl uttering sound when reached. If
the boat has the correct propeller set-up, operators should never reach the limiter, but if that happens it is a signal that
you should reduce the throttle and check with your dealer to determine the cause.
Always remember that during normal operation you should allow the engine to warm up gradually. Be sure the
engine is warm before accelerating. Pay careful attention to the gauges and the Check Engine indicator. Also, check
the oil level frequently during the fi rst 50 hours of operation since the piston rings and cylinders will require that period
to seat properly.
After the initial 50 hours of operation, the engine oil and fi lter must be changed.
This second oil change
is very important to ensure a long and trouble-free engine life.
(Note that the engine manufacturer does not recommend using synthetic oils until at least 100 hours.)
After
break-in all maintenance is performed at regular intervals.
See the
Scheduled Maintenance Checks and Services
section for more details.
Failure to follow the engine oil recommendations 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!
