Free Michigan Boat Bill of Sale
Michigan keeps boats in the family: while most states route vessels through a wildlife or natural-resources agency, Michigan titles them at the same Secretary of State branch that handles cars — one agency for the whole garage, with the WR-11 watercraft form standing in for the TR-11L cars use. The money follows the same clean pattern: a flat 6% with no local additions anywhere in the state, and no inspection of any kind. The trailer under the boat titles at the same SOS counter (over 2,500 pounds) or rides on registration below it — remember Michigan's permanent, non-transferable trailer plates when pricing the package.
