I purchased a 1981 sanger drag hydro in 2006 from a friend with no papers.(He said the gentlman lost the papers, it sat under a tree in Napa Valley since 1991) I went to registered it today. I had no problem with the trailer but, I was told the boat had a lien on it. The DMV gave me a # in Sacramento to call to get more info. Has anybody went through anything similar?
