Looking at replacing my old dud Wagner autopilot pump. It has several issues, parts are hard to come by. By the time I buy the needed parts and put in the time to fully rebuild it, I figure it is worth looking into buying something in current production. The Simrad pump and Octopus gear pump look similar in build, but a couple hundred dollars price difference. Furano has their accu steer pump that is bit cheaper than the Simrad, but more power hungry. Octopus also has a piston pump that looks to be the most power efficient, but is reportedly on the noisy side. While I am not easily bothered by noise, my wife is. Got a big old barn door rudder, so need plenty of hydraulic power, while hopefully not using too much electric power. So what are people's experiences and thoughts and these autopilot pumps? Pros and cons.
