Installation
Chuck,I'm not sure exactly how the pedastal is on the 336, but I was stumped for a short time on this one regarding the 290. The motor for the 4000 needs to install into the pedastal on my boat. This makes installing the little supplied bracket pretty much impossible. I found and copied the installation from another boat, and here is what I did.I carefull (very carefully) marked on the rear side of the pedastal the exact center of where the motor would penetrate the pedastal. I then drilled out a hole just large enough to get a sanding drum into (still needs to be somewhat smaller than the motor diameter). I carefull sanded the hole out to the motor diameter with frequent checks of the fit and position as I went. As I recall, I had already mounted the unit on the wheel, and had the wheel off, so that I could slip it on easily and check alignment. Need to make sure that the fit is tight at the motor / pedastal and that there are no obstructions inside the pedastal where the motor will sit (actually, check that first).The whole operation took me about an hour or so. I did not need to take the pedastal off (man did that look like an awful job). The autopilot works well and no problems to date. I suspect that there is a little pressure exerted on the connection between the motor housing and the drive unit, but the distance is not large and I think the lever load created is nominal.Besides, I really can't see any other way to do it on the Hunter pedastals. Wouldn't it be nice if they actually planned for future installation of an autopilot. My first choice was an ST5000, but could not find any way to fit the linear drive into the boat unless I left it in the box and just stored it there.Try to find another Hunter around with the same autopilot installed. That will help you work it out.Dan Jonas (S/V Feije)
