Please help me with the problem of a frozen bolt on the lower unit of an old 3 cylinder 70 HP Evinrude engine. The bolt is the rear bolt above the trim tab that is giving me an uncommon problem; at least uncommon for me. I can use a 24 inch 1/2" breaker bar and using all my muscle move the bolt an 1/8 inch counter-clock wise move, the bolt squeals loudly like the bolt is stripping the threads. I have turned the bolt about a 1/4 to a 1/2 turn with no change in the condition. My question, is should I keep on turning the bolt until it breaks or stripes itself out, or have I missed something very elementary.
I would have thought the bolt would have broke if it was entirely frozen. Or if frozen would have broken loose after turning the amount I have done. I tried both my torque guns 3/4 extended shank and my 1/2 inch with no success, they sit there.
A boat mechanic told me to heat the area with a torch while turning the bolt out. ?? For some reason this doesn't make sense to me. Hopefully someone in this forum can advise me one way or the other. I have used a torch on many a stubborn steel part to help assemble or disassemble, but never anything aluminum. Help please, anyone!
Thanks,
