Ok- the engine is out (without too much damage done to the boat...), and I have a one or two annoying questions...
I generally do not re-use nuts and bolts for the major components, so I'm replacing them. I was surprised to find grade 8 bolts and nuts on the shaft coupling; maybe a previous owner used them since they matched the color of the original engine? Anyway, they seem to have held up well with only minor surface rust, so I bought new ones at Ace along with nylock nuts and same washers. The question, as they don't seem to be that well machined-- how prone to galling is grade 8 steel, and would it be appropriate to use something like lanacote on the threads (I use that instead of oil on stainless hardware to prevent both galling and to protect the metal a bit). Or, should I use stainless fasteners?
