I have a tiller pilot for sale. It is a NAVICO TP5500, it was used as spare, it is in good working order complete with the mounting bracket for the tiller. . I also have a blue sunbrella cover for the T/P as well as a small dodger I had made to cover everything. I also have the optional wind vane attatchment with the aluminum pole that mounts on the stern pulpit so the T/P will steer to an apparent wind angle vs the compass heading. It was used on a 30' 7000lb sailboat, but I think it was rated for up to 14,000lbs. They always did a great job of handling the boat in all sorts of conditions. I can email pictures.
You can have the whole package with the manual for $250 plus shipping from the NYC area.
