It is way too much fun. It's the last refuge of "no speed laws apply" I can go boating any time I want and run as fast as I need or feel like. I was taking plenty tickets with my old Camaro and this just felt like the thing to do. I have seen several small block build ups, but none would work that great in a boat. Cars have the benefit of gears. Boats don't. Our races generaly are 70 - 100 mile legs in one day X 6/7 days for a total of 500 miles. To run a engine at 6500 / 6900 RPM, there's a good chance that parts are going to come apart. Some have tried and many have failed. Like in any race; you need to finish to win. Those UFO are geese!! You should see the pelicans try to get out of the way! We smoked one in Mexico in 2002. Here's another shot, from New Zealand in 2001
