Look at a pypilot, fairly inexpensive controller and works well.

Re: tiller autopilot with electric hydraulic pump

Will say we were in the land of the inexperienced as far as new computer items go when we started w/our project not too long ago. Not too bad now, but not going to write programs like Sean does (creator of pypilot).
You'll probably like his stuff he has on his forum. Sean has made an electric drive from a windshield wiper motor. Had it working on both a tiller and wheel.

Here are links to how we assembled our nav computer and then the pypilot if you are interested.

Re: tiller autopilot with electric hydraulic pump

Take a look at Pelagic autopilot. You can buy just the control and drive electronics package for $900, and wire it into your existing hydraulic drive. No need for DIY unless you just like doing that.

Re: tiller autopilot with electric hydraulic pump

Check our Simple H bridge, the HD version runs 12v.

IIRC max continuous power is 25 amps with the cooling kit.

You can also make up your own H bridge pretty simply as well.

Typo, I blame autocorrect.
It’s on line, Google it, no proprietary interest here...
