while under load today motor revved and prop seemed to be slipping. At low rpm it will move but as I throttle up it slips. also seems to have developed a new noise. I changed props but still same result

Sounds like a shift linkage and /or worn gear lobe issue.Of course with only limited info on the engine in question , that is my best guess.

thanx for the response. How could the linkage just fail? it shifts into forward and reverse. In reverse it appears to work fine. If this were a car It would be like a clutch slipping.
