I was rummaging around for some boat parts when I came across this which was in a box of bits from Blue Clipper our Van de Stadt 34 we sold 22 years ago.
TillerMaster was an early electrical self steering gear, it was very robust built of metal and I believe it used light aircraft actuators which were quite powerful and very reliable. The drive mechanism on ours was still working fine but the course setting and control had problems which I never managed to fix, plus we had a Clearway Autosteer wind vane gear which was a super piece of kit so repair of the TillerMaster was always one of those jobs you put off and was sold with the boat.
Blue Clipper was built in 1970, so I'm guessing the TillerMaster was from the early 70's, it was certainly old when we bought the boat in the 90's.

There's also a great instruction and repair article by Electric Marine which if it had been around back then I might have had more luck fixing our old unit.
