The steering helm seemed to have froze up on me over the winter. i went to http://boatwinch.com/mall/index.cgi..._category=engine part>cable&cart_id=522103757 (Im not even sure if this is the right helm for my Model) and found this. Well the helm fits inside of a large pin wich mounts the enigine. does ony one now were i would be able to find this pin?...or get the whole package for cheap?...This is for a 1979 johnson ML 100hp engine..When i replace this, what should i do to prevent this from happening again?
