Not sure if this is in fact the correct term or what is really happening, however, here's what is happening. When I move my gear selector there is no definate position or "click" for reverse, neutral or forward. When I do move into a gear it will engage the prop no problem. When I try to move from either gear to neutral the engine does go into neutral, but then the prop will start to rotate slowly as if it is slipping back into gear. The engine has not actually gone back into a gear but the prop will spin a few rotations then stop then may start doing it again a few seconds later. I can then stop that cycle by 'massaging' the shift lever either way to stop it.
