2017 OWNERS MANUAL /

To ensure proper break-in and lubrication, boat owners should not
remove the factory break-in oil until after the initial ten (10) hours
of operation and before twenty-five (25) hours. At that time, an oil
change should be performed by an authorized Ilmor/MasterCraft
dealer. Failure to follow the break-in procedure exactly as stated
will void the engine warranty!
NOTE: Before operating the boat for the first time, you must read
the engine manufacturer’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 engine immediately if the gauges and/
or video screen(s) indicate a problem. Low oil pressure and
overheating are serious issues and require immediate attention.
Abnormal vibration or noises.
These symptoms can be the first signs of trouble and should not
be ignored. Occasionally, hardware may work loose, mountings may
need to be tightened or the drive line may require attention.
Fuel, oil or water leaks.
Leaks can pose a serious safety threat. While all new MasterCraft
boats are lake tested at the factory to check for leaks, it is still pos-
sible that one may occur. If a leak does occur, it is quite likely that it
will happen during the first few hours of operation.
Vary the engine speed.
Never run the engine for more than three (3) minutes at any
constant RPM during the break-in period. Following this specific
instruction will assist in the proper break-in of rings and bearings.
Plane the boat quickly.
Operating the boat at low speeds places an excessive load on the
engine. Plane quickly, then back down to a slower speed.
First Hours of Operation
The first hours of operation affect the engine and drive train more
than any other component on the boat. Therefore, it is very import-
NEW BOAT
BREAK-IN
The first fifty (50) hours of operation are the most important for establishing acceptable wear parameters
for the boat. Proper break-in will ensure maximum performance and the longest possible power-train life.
The break-in period allows moving parts within the engine and transmission to wear-in properly. All Master-
Craft boats are lake-tested on the water before leaving the factory, but the break-in must continue for the
first fifty (50) hours of your ownership.
