I have heard claims of 30 MPH but I don't know for sure. When I made the video I was using an over sized lifting prop. Since then and after the engine break in I installed a new Grim Racer 36mm X 55mm prop it's really fast with the hull out of the water on the last 2 or 3 inches of the hull. I can only guess but seems like its going around 35 MPHTEK ProBoat Formula Fastech NitroComment
