Seat-mounted?
I took the picture but I didn't install the unit. It came with the boat when I bought it used two years ago.I'm not sure what you mean by "seat-mounted", unless you are referring to diagrams in tha manual. I found the 1000 manual on the web, and the distance from the rudder pivot point forward along the axis of the tiller handle is for mounting is 18 inches which is the same as mine.From there you need 90 degrees to the cockpit wall. Wouldn't this always be aft of the seats? Looking at the manual, your 1000 is basically the same shape and size as my 800. Sheesh, I didn't realize that Autohelm and Ratheom are the same company/product!...RickM...
