Raytheon Auto Pilot. Worked when I took it off the boat.
Recently replaced with new nmea 200 unit.
One head unit.
One auto pilot,
One heading sensor, and
One rudder sensor.
2 manuals which I believe are for these units.
What you need is a hydraulic pump, which I kept on my boat (mine is a 13 amp pump)
What I have is pictured below;
$250 shipped to continental US via USPS with tracking number. I accept paypal or cash.
I'm sorry , I cannot answer technical questions about it. I do know it worked great but I didn't want to deal with the 0183 to tie it into my new chartplotter.
