I have seen the boat & unfortunately, I doubt you will get much for it.
It's a heavy hull with lots of holes in it. The entire cockpit would need to be totally replaced with bolsters, rear seat, sun deck, dash. It need lots of holes filled on the deck where the gun mounts were & generally, a whole boat load of misc. parts will be needed.
After all of those expenses, a complete paint job will be needed (after the hull sides are straightened out), plus the engines, drives, tabs, props, gauges etc...
I hate to sound negative & I certainly don't want to sound like I'm bashing your boat, but that is going to be a major tough one to sell.
