 Protect your Mercury motor during winter with proper storage and winterization. Ensure you flush the motor with fresh water, change the engine oil and filter, add fuel stabilizer, grease fittings, tend to your battery, inspect the propeller, and cover the motor and boat with a waterproof cover. Regular maintenance and winterization will extend the life of your Mercury motor. Sierra offers a complete range of accessories and parts needed for proper winterization of your Mercury outboard motor.
