All gaskets were Merc. Fuel is 91 non ethanol. Engine tune, just the limiter bumped to 5400. Motor checks out great. Runs as it should. I do run mufflers though.

I remembered that I have seen somewhat the same from a smallblock with thru the prop exhaust and his problem was a water shutter / aka flapper valve was lodged down in the Y pipe, that caused a exhaust restriction. this restriction added exhaust heat and like I said before - exhaust gases can be corrosive.
for your app in the pic -------------
Maybe possible an exhaust problem of some sort - back pressure or restricted exhaust flow from the mufflers installed - IMO this could be a good guess here and possible a fuel additive used ??
