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 first fifty (50) hours of your ownership.
To ensure proper break-in and lubrication,
boat owners should not remove the fac-
tory 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 on the Ilmor engines by an authorized Ilmor/Mas-
terCraft 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 manufac-
turer’s manual completely in addition to this Manual!

very important:
• Maintain the proper oil level. Untilthepistonrings,cylinderandotherworkinginter-

watched. (This continues to be important after break-in, as well).
