You can check out Beavertail's 75 mph rocket sled this weekend at the Tampa State Fairgrounds. And that's not a typo, the Lightning's top speed with the 200hp Evinrude is really 75 mph. Here's a shot of the GPS to prove it.
This boat is actually rated for a lot more power and the next one is being rigged with a 250hp Mercury Pro XS. I'm thinking 80 mph is a possibility. And no, I won't be replacing my 70hp BT3 with a Lightning any time soon. I don't need that much boat but if I ever wanted to make a go at the redfish tournament circuit, it would be on top of my list.
