Just finished up getting the motors freshened up. Now I want to see about getting some new props to get some more top end out of her without having to turn the motor 6000rpms. As of now @5000rpms the boat on GPS will 65-68mph.. I would like to do 75mph top@5500rpms. I have 3 blade props now? Any help will be appreciated. The boat is a 35ft Fountain Lightning with twin 468ci. BBChevy Engines. Appx. 1100hp combined.
