I am trying to diagnose the problem I have with my A4. It's running fine in neutral -at least sounds fine to me- but when I put on forward [direct drive], and I open the throtle, the engine refuses to revv and I get not enough power at the propeller to move the boat efficiently. I can move the throttle back and forth with no effect on the engine output -as if the engine could not turn the shaft and propeller. But the shaft turns freely by hand, and I know it is not a fouled propeller as I already had this problem, overhauled, cleaned the prop, and had the same problem afterwards. Things seem to get worse with time though, having less and less power available uner load. To the point that I don't feel comfortable leaving my slip as the slightest wind would make the boat unmanageable dur to lack of power. Anyone has a suggestion for the diagnosis? I appreciate your inputs! Thanks.-- Olivier
