Update: I decided to do it the right way and bring it up to my name first before I sell it.
Problem is, previous owner only gave me a bill of sale with the hull number on it and such. I never got a registration from from him. It’s weird he has MN address but the registration tags on the boat are WI.
Can I just bring the bill of sale to Iowa Recorders Office and they take care of the rest? I have no clue how to contact this guy to get the registration.
