I bought a boat without an engine that has a teleflex steering cable. I found a good engine too cheap to pass up, a 40 hp Johnson (I think it is a early 70's, not sure though) But, the Johnson I purchased doesn't have a teleflex hook up. The Johnson was attached to a boat that had a series of pulleys and cables for steering. I need a conversion kit to make this work. Is there such a kit? how much?
