Ok I'm new so excuse me if this is dumb, but one of the two bolts attaching the sea water pump bracket simply will not come off (Merc 5.7L 350 CID 1995 v-belts). The nut rotates both ways but the threaded bolt prong part stays in place. There is no backing nut to the threaded prong - it looks like it is screwed into the engine block. Does this mean the thread of the bolt and engine block are toast? Or is there some tool or technique I can use to free it? The prior owner used two nuts on the prong/bolt thread - one came off easily. The other nut is stuck. The lower bolt came out easily.
Also, would you big dogs in the forum replace old nuts/bolts/washers with new stainless steel to re-attach the bracket to the block?
