Hello all. I just purchased a 2001 Challenger with the 240HP Mercury M2 jet drive motor. I need to know what the proper way is to flush this engine. The boat did not come with the mercury manual, and it looks as though they are like gold. When i looked in my seadoo manual it refers me to the mercury one. If anyone has the procedure on how to do this it would be greatly appreciated.
