07 Puma w/ 225 Pro XS loaded with 450 lbs. of people 20 gallons of fuel in the rear tanks water in wells and full of gear I can get 71 w/ 26 fury or 73 w/ 27 tempest before the boat starts to chine. I am still trying to learn to drive the boat to stop the chine, hopefully once I get it figured out I will gain a few more mph.
