Went through this a good bit, may be alternative but this has been my experience. Kansas is a non title state and Missouri titles boat, motor, and trailer separately. Easiest if the previous Kansas owner notifies Kansas Wildlife and Parks that he is selling which he is required to do by law. He could provide you with his copy of registration and sign off on it or you can contact the agency with your engine serial number for verification. Somehow it never seems to be easy sorry to tell ya.
