Yes, I did install my own autopilot but,
years ago, I bought the Autohelm 800 and installed that with a bracket that I made up myself out of Bronze pipe and Teak. So this time around when my 800 bit the dust about two years ago, I bought the ST 1000 + and only had to change the electric outlet. I have my autopilot mounted on my gasoline compartment cover because I really don't care if water gets into it, as it is open to the cockpit. At the time when I had bought the 800, you didn't need extensions for it. The push rod could be adjusted by screwing it in or out to get the desired length. The new ST 1000 seems to work the same as the 800 did. It's a little bit noisier than the 800, though. Chuck,--I'm not sure about the extensions, but if I were you I'd order the bracket for it and consider installing it on the Starboard side only because you're more likely to need to get into the lazerette compartment for ropes and gear than you are the gasoline compartment. If I had it to do all over again, I would have just bought the mounting bracket. The one I made is stronger and just as easy to take on and off, but it sure looks ugly! I know that you guys are going to love this autopilot as I do. These are some of the things that I've done under sail with this autopilot steering my boat; 1. used the head. 2. made a clam chowder from scratch. 3. Cook all my meals and eat while keeping a constant lookout. 4. Lay inside the folks'le reading a book with a mirror to glance out my opened forward hatch. 5. Take a shower on the forward deck with the bag raises from the Jib halyard. 6. On extremely hot days, I've climbed down my stern ladder and hung on to it with both hands while floating in the water. I stopped doing that last one when my wife and I were sailing near Cuttyhunk Island in the Vineyard Sound one day, and saw a large fin in the water. OK. It's true. I'm a Nut!
