Hello everyone I have a 1989 88spl evinrude outboard and I have a omc remote control I can not figure out how to get this cable adjusted rite I cannot get the warm up throttle to give me any rpm change I have adjusted this thing all different directions I have taken apart the controller and really don’t see anything broken or worn but I’m not really sure what I’m looking for I don’t know how to determine if cable is stretched any help would be appreciated thanks
