  This is an older engine with carburetors and I don't think any software will pinpoint the problem. It is not fuel injected and has no computer to control the fuel. I think I have it narrowed down but thanks for the info anyway. I am going to try a 3 blade 9 degree prop and see what happens. I have one for backup and will install it when I get back to my place on the lake. Like I said its running fine but just worried about the top RPM's this Mercury is supposed to turn. I know lots of things could cause this but I just don't want to burn this engine up again. Cobra
