Don't think you're going to get that cash back, but I would be stern about the pistol. Filing a police report is a bad idea. it was a part of the deal, no different than cash. It's no stolen at this point. That's a false police report and bad juju. If you can confront him tell him you're taking the boat and the gun and calling it even, or you can take him to court, but that at this point, this is on principle and you're not letting it go.
He might bow up and call trespassing on your property. be prepared to show you own the boat and the gun to a LEO in case he decides to be cute and call them. remain calm, remain respectful despite his reactions. If an LEO shows up, remain even more calm and more respectful. you will get a lot farther that way.
