Why Winterization is Critical
Winter weather can cause serious damage to your Mercury® outboard. Professional winterization prevents costly repairs.
Prevent water from freezing in cooling passages and cracking engine blocks
Protect internal components from corrosion during extended storage periods
Prevent fuel degradation and gum formation in fuel lines and injectors
Ensure your engine starts easily and runs smoothly when boating season returns

Best time to winterize before temperatures drop. Avoid the rush and ensure availability.
Winterize when nighttime temperatures consistently drop below 40°F (4°C).
