Hey guys, I've got this old evinrude kicker motor laying around and I have no idea what year or hp it is. The color is grey with a white and grey hood, and the hood is shaped like it might be mid 60's. There are no numbers of any kind anywhere on this thing. The only numbers stamped in this are the point gap and the number 57 stamped on the flywheel. Can anybody tell me where to look or maybe what size or year or anything this is? thanks
