[C320-list] Shaft Alignment

[Pat Moriarty]

The key just keeps the prop from spinning on the shaft and the taper 
keep it snug on the shaft. So the key takes the torque and if it were 
undersize you would only get a jolt when you went from forward to 
reverse but it would wear the taper some. I would think you had a 
bigger problem like the nut was not tight enough and the prop could 
shake and that caused the key to be loose, you might also check run 
out in the shaft if it is not in the water yet.
