looks a bit nuts, I wouldn't care if it was my bike, a bit of water never hurt a quad as long as its cleaned out properly, I dunno what damage hitting the water hard would be though at those speeds if you wipe out, problem is that my quad is a king-quad 300, a 91 4x4, so its not exactly "newer" or does it have the power to even go that fast, although it is submersible....
