The rst fty (50) hours of operation are
the most important for establishing accept-
able wear parameters for the boat. Proper
break-in will ensure maximum perfor-
mance and the longest possible power-train
life. The break-in period allows moving
parts within the engine and transmission to
wear-in properly. All MasterCraft boats are
lake-tested on the water before leaving the
factory, but the break-in must continue for
the rst fty (50) hours of your ownership.
To ensure proper break-in and lubrication,
boat owners should not remove the fac-
tory break-in oil until afer the initial ten
(10) hours of operation and before twenty-
five (25) hours. At that time, an oil change
should be performed on the Ilmor engines
by an authorized Ilmor/MasterCraf dealer.
Failure to follow the break-in proce-
dure exactly as stated will void the en-
gine warranty!
NOTE: Before operating the boat for the
rst time, you must read the engine manu-
facturer’s manual completely in addition to
this Owner’s Manual!
Please follow the break-in procedure
carefully. Close attention to the following
is very important:
• Maintain the proper oil level. Until the
piston rings, cylinder and other working
internal parts are thoroughly seated, oil
consumption can be high and must be
carefully watched. (This continues to be
important after break-in, as well).
• Pay close attention to the gauges and
video screen(s). It is important to stop the
