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?

You do not want to use stainless bolts. SS bolts are not as strong as mild steel. SS is maleable and will stretch and loosen with shock and vibration. Might not be a big problem with the modest torque loads on these small diesels, but it is not recommended. The numbers on the bolts are about strength and there are specifications somewhere about what should be in the coupling. I think the engine or transmission folks will have the specs on the coupling bolts you should use.

Well, ok. The numbers are no longer readable on the bolt heads. I'll ask my mechanic (and the rebuild kit supplier) and see if they have any idea.

Thanks, guys-

Ray

Look for the number of lines on the bolt head. I think 3 is the minimum for that application.
