look under the splash well.......look under the bow........maybe there

Probably had the transom replaced at some time and they covered up the original HIN. When I did my transom in my ventura, I accidentally filled the HIN with resin. I had to scrape the resin out so the HIN was still visable.

The HIN on there is just a generic number issued by the state to register the boat. Probably the owner had no documentation, so they just registered as a homebuilt.

Curious though, did you get the rest of the boat with that purchase??
