Be pretty noisy. 6-53s are pretty dang loud. We used to have them in the Avalon Shore Boats that did the cruise ships, they made for a long day.
Not to mention the description is "parts only" with no photos of the interior. Still, it looks like a boat and they're not making them anymore so enough money could probably get it in the water again. I hope to be in the market for something similar in a few years but even if I were there now I would pass on this one.
