This document summarizes boat registration requirements in Kansas. It notes that Kansas does not issue boat titles, but only registration. Boats must be registered with the Department of Wildlife & Parks and display a registration number starting with "KA" and sticker. The registration certificate should be checked for any liens before purchasing a used boat. Boat registration records can be searched through Boat-Alert.com, though not directly on the state website. Registration fees are around $33 and vary by boat length.
