How do you find out what year your mariner?

To determine the year of your mariner, check the serial number located on the engine's identification plate or on the transom bracket. You can often find the year by referencing the manufacturer's website or contacting their customer service with the serial number. Additionally, many online resources and forums provide databases for specific models and their production years. If you have the owner's manual, it may also contain information about the year of manufacture.
