Fuel can deteriorate, batteries discharge, corrosion continues, and water hiding inside a gearcase becomes especially concerning where freezing temperatures are possible. Mercury's exact winterization procedure varies by engine, so your owner's manual should always be the final reference for your model.

Modern outboards, including those from Mercury Marine, are designed for durability and can deliver thousands of hours of operation when properly maintained. However, engine hours alone do not determine overall condition. Outboar …
