Would that really help?
I thought that if the two dissimilar metals were electrically connected, you
had a problem. Hanging a zinc guppy overboard will sacrifice the guppy, so
why wouldn't the galvanized chain be sacreificed even if it was seperated,
but electrically connected?
Electrolysis can be a real problem. I had a bridle w/ almost all ss parts:
chain hook, ring, shackles and thimbles. Everything except about 5 links of
galvanized chain between the chain hook and the shackle connecting to the
ring. Those links quickly became rust, so I replaced the ss with galvanized.
Of course, all this was in direct contact with each other, but I suspect
that electrical contact is enough to creat a problem.

I just found a 90 pound stainless steel plow to use as a mooring
anchor. The guy I got it from said that he thinks there is an
electrolysis issue if you use galvanized chain. He said that there was
something I needed to do, but couldn't remember what.

Anyone have any clues for me?

There is.

Install a monel or equal link between the S/S and the galvanized items.
