Just done here by EB MARINE. The boat (288 Sunsation) was GPSing 65ish with a 496Mag/375. The only differences between the 375 and 425 are the cam and ECU. Upgraded to the 425MagHO cam and had Dustin reprogram the ECU to 425/Whipple blower specs and the motor makes 623HP now. Runs 78/79 GPS. No need to move the seat. Any boat that picks up that much speed may require some rerigging. That would be considered a good problem ...........He has put tabs on the boat. I think he has hydraulic steering in his future plans. Any boat running over 75 should have hydraulic steering.
