I was able to remove all bolts but one- of course. The last bolt is a hex head bolt. The inside is rounded off. Not much room for anything to grab it. Thinking of drilling it. You mentioned a p grinder. Is that a grinding wheel on a flexible shaft. That might work. Also cant remove shock mount without breaking them. They only cost 90 bucks apiece. Starting to get a little upset. Time for break and cool off. Once again this is a 97 75hp force.
