I have come across a 19' Center Console made by North American Boats. They went out of business forever ago but apparently it is the same mold as a 19' Mako. Looks just like a Mako to me. Anyone ever hear of North American or know much about them?
For a boat that old (and at a good price I assume) the overall condition of the boat is more important than any history. If the floor and transom is solid and the engine runs then that's probably all that matters.
It does look a lot like a Mako. I've looked on a couple of search sites and the only thing popping up are some boats for sale.
