MasterCraft ProStar 197 User Manual

• 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. These symptoms can precede trouble and should not
be ignored. Occasionally, hardware may work loose, mountings may need to be tight-
ened 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

First Hours of Operation
Each engine manufacturer has detailed and specific 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.
New Boat Break-In
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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 opera-
tion 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 recom-
mendations listed in the engine manual
can cause additional engine wear and
increase the possibility of engine compo-
nent failure. Damage to the engine due to
incorrect oil usage can be costly to repair,
and is not covered by the warranty!
