2004 Sea-Doo Challenger X Want to break the law of gravity? Here's your accomplice. The Challenger X has been thoughtfully engineered to take wakeboarding to new heights. Launch your vibe with a radical black hull, custom matched trailer, built-in cooler and water-rippling CD stereo system. Stick big air with a collapsible aluminum tower that provides a solid tow point seven feet above the water line. Dial it in with 600-pound-capacity fat sac that paves a curl smoother than a half-pipe. Eliminate take-off drag with the power of an optional 250 hp OptiMax Mercury M2 jet drive. Just don't blame us if air traffic control picks you up on radar. - Sea Doo Challenger
