Just picked up a 70 something Starcraft mariner 18ft, they're rare around here and so when this came up I jumped on it. Got it for a decent price so I paid the man his money and towed it home. Now that I'm looking at it its rougher than it first seemed. Knowing nothing about boats, nothing at all, I could use some information. First is where do I find a HIN number? I cant find one. Would these years have a second hidden one? If there isn't how do I get one reissued?
