This year I drove one of these (910 model wich was a 29 footer) twin stock 502's and MAN! WAS i IMPRESSED!!! 80-82 mph!!! There was a flat pad underneath it, almost I'd say 5 foot in front of windshield wich sure helped to get on plane but even more to go that fast!
I don't know for the model you are looking at but they seem to be fast boats!
