Picked this up this past weekend. I took off the azimuth ring to paint the pod. I broke the stud that the knurled nut is on when I took it apart. and still can't get the left over stud out of the nut. Heat hasn't helped, and am worried about putting too much heat to it. It has a demill cut in the casting that has been welded back up. What do you all think? What are these going for now?
