Therstfty(50)hoursofoperationarethemostimportantfortheboat.Properbreak-inwillensuremaximumperformanceandthelongestpos-
sible 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.
New Boat
Break-In
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 per-
formed on the Ilmor engines by
an authorized Ilmor/MasterCraft
dealer.
Failure to follow the break-in pro-
cedure exactly as stated will void the
engine warranty!
NOTE: Before operating the boat
for the rst time you must read the en-
gine manufacturer’s manual completely
in addition to this 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. It
is important to stop the engine imme-
diately if the gauges indicate a prob-
lem. Low oil pressure and overheating
are serious issues and require immedi-
ate attention.
• Abnormal vibration or noises. These
symptoms can precede 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. If one oc-
curs, it is most likely to do so after a
few hours of operation.
• Vary the engine speed. Never run the
engine for more than three (3) min-
utes at any constant RPM during the
break-in period. Doing this will assist
in the proper break-in of rings and
bearings.
• Plane the boat quickly. Operat-
ing 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
 Eachenginemanufacturerhasdetailedandspecicrequirementsforproperenginebreak-in.
That information is found in the engine manual supplied, and must be followed exactly as indicated.
Failure to do so could cause engine damage and/or failure that is not covered under warranty.
After Break-In
Once the break-in period is over, the boat may be operated continuously at any speed, but not
beyond the maximum indicated in the engine manual.
 Theenginesareequippedwithrev-limiterswhichwillcausea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 an authorized MasterCraft dealer to
determine the cause.
Always remember that during normal operation you should allow the engine to warm up gradu-
ally. Be sure the engine is warm before accelerating. Pay careful attention to the gauges. Also, check
theoillevelfrequentlyduringtherstfty(50)hoursofoperationsincethepistonringsandcylinders
require that much time to seat properly.
See the Scheduled Maintenance Checks and Services section for more details.
Failure to follow the engine oil recommendations listed in the engine manual can cause ad-
ditional engine wear and increase the possibility of engine component failure. Damage to the
engine due to incorrect oil usage can be costly to repair, and is not covered by the warranty!
