The model and serial numbers of the vertical drive should be located on the engine model and serial number plate. If the vertical drive model and serial numbers are not recorded with the engine model and serial number, they can be found on a plate located on the vertical drive. The transom mount model and serial number plate is located on the inner transom plate.
