[QUOTE="Whoopbass, post: 277229, member: 2243"] I have a modified 15' v-hull and have a 1987 Evinrude 25 hp motor on it that has thru hub exhaust. It does 25 mph on the GPS. I had a 1978 Evinrude 25 hp with non hub exhaust and I got 27 mph on the GPS. The tests were done on different days but I am sure the non thru hubs are just as fast as the thru hubs. The gear case is smaller so there is less drag so that could be a reason it was faster. The 1978 motor was pretty cherry and had less hours then the 1987 motor so that probably played a role in it.
