bkrs, your not getting much response from the Mercury guys! Dave will fix you up, he knows his stuff. I have first hand experience with that dirty sonofagun cover that you are working on! Old Carl got SOB several times before I got mine off. I tried heat several times. Every kind of penetrating potion that I could find. I tried to melt wax into the treads. Hammered the case on both sides. Then I went nuclear! Ya get to a point where its gonna come apart or throw the darn thing it the trash! I built two different tools and I kept breaking the pins off or bending them so bad they wouldn’t stay in the holes. I drilled the darn thing out! Literally, see the pictures! Hope you find a better way.
