I am going to drop the engine in today for a fit check. I will set the batteries, trim/tilt pump, and the trim tab pump in place to see where to fit them and where I can maybe put in a thru hull with seacock. Once that is done, I will pull the engine back out and lift the boat off the trailer to see what I can do with those rollers. The outside end rollers run just inside the chine so I don't thing I can move them out. The brackets don't seem to be adjustable side to side.
