Installed new Raymarine ST-2000+ Autopilot. Purchased from Barton Marine. 3 year warranty.
Installed new connectors and wiring for power and NMEA 0183 data connected to the output of the multiplexer.
All works well so far.
Did sea trials and calibration on 24 September 2016.
PD. December 2021
After 5 years of not-intensive use the ST-2000 finally died. It had been unreliable for the last year. I opened the unit to find a mess of broken and worn gears. I have now replaced it with the Simrad TP22. So far it appears to be a big improvement over the old Raymarine.
