With only having a 12 footer, and I assume it is alum.....which ever is the lightest weight. Probably not much difference but the 3 does have a bit more HP providing it is tuned and running properly.
Thanks, thought it would be close. I have a 62 3hp Evinrude pushing it now and have clocked it at about 4.2 mph with a GPS. That's at 6240 elevation with about 400lbs in it. It runs real nice.
