I have a 73 50 hp johnson power shift 2. My problem is when the remote throttle doesnt move much when using the remote throttle only leaver but will move all the way to wot when using the gear and throttle leaver. has anyone else had this problem or know whats wrong with it. ive removed the cables and greased them and they move freely. Ive also taking the remote box appart but nothing seams to be wrong but i could be wrong about that. i upload a video showing the throttle only, then gear and throttle.
