I have a 1966 33hp Ski-Twin (manual shift) with a worn clutch dog and forward gear. Is it possible to get an entirely new gear set with the better designed clutch dog engagement? If so, what years will work?<br /><br /> As a side note, is it possible to machine the edges of the clutch dog and forward gear so the gear won't pop out? Anybody tried this? <br /><br /> Thanks,<br /> Jake
