To determine the year of a 20hp Mariner outboard with the serial number C182222, you can typically refer to the manufacturer's serial number identification guide. For Mariner outboards, the letter "C" often indicates the model year range of 1980-1989. Specifically, the serial number suggests that this outboard was likely manufactured in 1982. However, for the most accurate identification, checking with a Mariner dealer or the manufacturer's resources is recommended.
