Our guide to outboard winterization will help you safeguard your investment and increase the lifespan of your outboard. With appropriate winterization, you ensure optimal performance of your outboard once warmer temperatures come.

Key Steps to Take for Successful Outboard Winterization 

Knowing your outboard's specific model details will help in the process as different models may need specific methods for successful winterization. Always seek accurate information from brand websites regarding original equipment manufacturer (OEM) products. Consider details like flushing the engine and adding a fuel stabilizer to the remaining fuel in the engine. Drain water from the engine to avoid potential freeze damage.

Additional Tips for Your Outboard Winterization Process

Inspecting exposable metal parts and removing deposits using a wire brush or abrasive pad will be an added benefit and help maintain the overall health of your outboard. Additionally, corrosion protection is invaluable; use anti-corrosion sprays on external surfaces.
