New Boat Break-In
e first fifty (50) hours of operation are the most important for the boat. Proper break-in will ensure maxi-
mum performance and the longest possible power-train life. e 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 factory break-in oil until
after the initial ten (10) hours of operation. At that time, an oil change should be performed on the Indmar
engines by an authorized MasterCraft service technician at an authorized 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 man-
ual 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. (is continues to be im-
portant after break-in, as well).
• Pay close attention to the gauges. It is important to stop the engine immediately if the gauges indicate
a problem. Low oil pressure and overheating are serious issues and require immediate attention.
• Abnormal vibration or noises. ese symptoms can precede trouble and should not be ignored. Oc-
casionally, hardware may work loose, mountings may need to be tightened or the driveline may require
attention.
• Fuel, oil or water leaks. Leaks can pose a serious safety threat. If one occurs, 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) minutes at any constant RPM dur-
ing the break-in period. Doing this 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
Each engine manufacturer has detailed and specific requirements for proper engine break-in. at infor-
mation 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.
e engines are equipped with rev-limiters which will cause a fluttering 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 gradually. Be
sure the engine is warm before accelerating. Pay careful attention to the gauges. Also, check the oil level fre-
quently during the first fifty (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 additional
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!
