MasterCraft 2009 MariStar X-Series New boat break-in, First Hours of Operation, After Break-In

new boat break-in

The first fifty (50) hours of operation are the most important for the boat. Proper break-in will ensure maximum performance and the longest possible power-train life. The break-in period al- lows 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 per- formed 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 manual completely in addition to this Manual!

The VW diesel engine does not require an oil change at 10 hours. The VW diesel engine requires an oil change every year or 200 hours of operation. See the VW engine manual for spe- cific guidelines and requirements to maintain the warranty.

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 immedi- ately if the gauges indicate a problem. Low oil pressure and overheating are serious issues and require immediate attention.

•Abnormal vibration or noises. These symptoms can precede trouble and should not be ignored. Occasionally, hardware may work loose, mount- ings 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 during 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 require- ments 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 con- tinuously at any speed, but not beyond the maximum indicated in the engine manual.

The 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 al- low 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 frequently during the first fifty (50) hours of operation since the piston rings and cylinders require that much time to seat properly.
