where are all the experts? no replys to last three posts. I would like to know how much trouble to convert from a tiller to remote on a 1987 60 hp Johnson, and if any one knows where i can find a good used powerhead for a 1987 70 hp Johnson. Third post was for a tack for a 1975 40 hp rude with point ignition. Someone please answer, I have faith in you all.
