Well, I’m glad no one has told me the perimeter bolts have to be removed. That’s a relief.
Although its tough to see in the pic, there is a slight gap between the nut and the puller. I considered putting a suitable washer on top of the nut and having the puller push against the nut vs the crankshaft end. My rationale being it would increase the surface area between the puller bolt and the crank and reduce the likelihood of damaging the end of the crank. I still may depending upon responses to the idea.
As for the thin washers. I put them on to increase the contact area between the bolt heads and the OMC washers which have a pretty large ID vs the underside of the bolt heads. That was the case even with the original shoulder bolts. If they’re getting smashed, its not very much.

I wouldn’t do it. I believe you may put the threads on the crankshaft at risk.
