I have an Autohelm 4000 wheel autopilot in my Catalina 28. Since new it has given me fits. Seems to like to turn 90 degrees to port when ever it feels like it. Also the compass readings are totally different than my ships compass, handbearing, and GPS on certain headings. I have done all of the recalibrating etc. Have contacted the manufacture etc. Recently the pin that hold the engagement lever in place sheared. I took it to the Factory authorized service center for repair. the cahrged me 42 cents for the part and $35 for 5 min labor. I left on a cruise and with in 30 minutes it had broken again. Now to get to the point. I've had it with Autohelm. A friend bought a X brand from West Marine when they told him it used a lot less power and they get half the returns. Another friend has a new unit and is on the 5th control head in less that one year!! Anyway. Does anyone have any recommendations for a replacement unit? If I am going to spend another grand, I'd like to get it right this time. Looking forward to some help!!
