Important Information About Flushing Procedures
MerCruiser sterndrive and inboard engines are used in many different vessels for a variety of recreational and commercial
applications. Choosing the correct flushing procedure for your engine will depend on the engine model, and in some cases the
marine hardware and cooling system water supply features provided by the boat manufacturer.
Contact your authorized Mercury MerCruiser dealer for information about the best flushing procedure for your engine and boat
model.
