I'm looking at trying to breath some life back in to an 89 Mercury 8hp. The only problem that I've discovered so far that I'm not sure what to do with, is the prop shaft. If I attach a pointer to the cavitation plate and rest it even with the top edge of the prop shaft, then slowly rotate the shaft, I can see that there is an 1/8th inch (1/16th high and 1/16th low) of warp in the tip of the shaft. Buying a new shaft is out of the question because that and the other parts required to fix this motor would put it well above what it's worth. So what I'm wondering is whether a machinist could straighten that shaft or not. Anyone had any experience with doing this before?
