I'm looking at buying a 1979 Robalo but the title has a NJZxxxxxxxxx ID Number. I know the old boats in NJ when ID'ed this way (as homemade)before MFG Vin # but the title and registration both have proper manufacturer description and registration numbers on them. The boat clearly has a MFG registration # on the transom but not on the title. Does anyone know whats going on with this?
