1972 Crestliner 17 footer, pretty decent shape. Paint is way too fresh to be original, so I think it's been repainted. Big question...can't find the data plate. It's not on the transom, not on the dash, where else could it be...and if it's nowhere, how big a problem is this? With Illinois DNR (to get title and registration?) With the USCG (if they spot-check me?) Any help is greatly appreciated, as always...
