White Water Jetboat Racing is a lot of fun. Basically four classes. crate motor (such as ZZ4) 360 ci and under, up to 454 ci and unlimited for anything larger than 454. Our team ran a Kwik Kiwi hull from New Zealand with a Fuel Injected, Whipple Supercharged 502 running 750 hp. It was not the fastest boat, but it was over 454 ci, so we had to run unlimited. There are hardly any boats left in the sport. That is too bad, because it is a cool sport and easy to get into. For more info see http://www.jetboatracing.com/
Here is our team boat. I crewed and navigated.
