In the US, we register power boats with the state Dept of Motor Vehicles. A phone call (or several - they're not the most helpful of groups) should get a name of the registered owner, which would go a long ways in determining whether a sale is legitimate.
Nope, no required national registration scheme, or insurance requirement over here.
Datatag tried to create a compulsory scheme for skis 20 years ago with the help of insurance companies and some bodies of water, but it never became a legal requirement.
