Winterization is an essential procedure for every outboard engine. As temperatures drop, the risk of engine damage increases significantly. During winter, residual water in the engine can freeze leading to engine block damage. Additionally, water or acids from oil breakdown in the engine oil and gear oil can lead to rust or etching of bearings, gears and housings.
The fuel system can suffer from condensation and fuel breakdown, resulting in poor performance when spring arrives. By winterizing your outboard, you ensure that all components are protected, helping to prolong the life of your engine and maintain its reliability.
