I would take the shaft and coupling to a reputable prop/shaft shop and have
them properly mate the shaft and coupling and drill proper depressions for
the set screws.
I did that when I re-powered Touche' and bought a new shaft as part of the
upgrade. Did it with the boat in the water.
If you're brave, you can do it without a haul out. My diver buddy has a
collection of "spare" shafts. He will loosen the packing, pull the shaft
to be worked on, and temporarily replace it with one of his "spares".
