they are both 927 HP (restricted), the v-12 at 8500 rpm and the sterling at 6500 rpm, they weighed 10,560 coming out... so other than more HP, more tunnel width, more hull length plus rudders.... it was pretty even with the 850 boats. :ack2: It was still fun though. They could of ran off and hid from the drop of the flag, but they made a show of it for the fans, plus they were good guys to talk with and hang out with.
