onplane, on the same forum i got the pro xs results, it showed the 250 sho running 74.4 mph @ 6090 rpm and the 225 sho running right at 74 mph @ 6000. there is a 250 yamaha 2 stroke that says they are getting 75 mph @ 5950 rpms. and just like Darth stated there is a 250 Evinrude HO running 79.1 mph @ 6200 rpms
