Can someone please help offer some suggestions of what maybe the problem with my motor. I was running my boat today with my 2 F250's at about 4400rpm and all of sudden one of them starts making this horrible loud exhaust noise that sounds almost like a lawnmower. The motor still runs fine and has power, but the noise is terrible. Does anyone have any suggestions they can offer?
Thank you for any help provided.
