I've got a 55#w/auto pilot and co-pilot. Works like a dream. I have to agre with cane pole about the up and down part, and I can't stress this enough, don't ever forget to slide the locking ring up against the base every time you dock the motor. If you have ever seen one of those things raise up and go in the lake at about 40 MPH you will know what I mean. Ugly sight.
