Re: mercury controls
Funny, I don't remember. I had the control loose and to get it out of the triangular hole in the boat, the lever HAD to come off. I popped the set screw and applied a serious amount of high quality penetrating oil to everything associated that I could see. After a good soaking, I tried to prise it off with 2 very large screw drivers, then a hammer on the screwdrivers and finally the saw. I think I put the blade between the handle and the control housing as it was the smallest diameter and all that diameter had to come off anyway. I was surprised that the saw worked it's way through it very easily considering the fact that I was sawing metal.
