How to run an outboard motor during winter?

As the winter season arrives, boat owners need to take extra precautions to keep their outboard motor running smoothly. Winterizing an outboard motor is not a challenging task, but it requires careful attention to details. Here are some tips on how to run an outboard motor safely and efficiently during winter:

1. Use the right fuel: It is essential to use the correct fuel for your outboard motor. Check your owner’s manual or contact your dealer to determine the appropriate fuel type for your engine. Use only marine grade gasoline with a minimum octane rating of 87 as it ensures that the engine runs smoothly and consistently even in colder temperatures.

2. Protect the fuel system: Fuel systems can be vulnerable to water, condensation, and fuel breakdown, leading to engine failure. Therefore, it is essential to treat your fuel system with a fuel stabilizer, which prevents moisture buildup and gas oxidation during winter storage. Add the fuel stabilizer to your fuel tank and run the engine for at least 10-15 minutes to ensure the stabilizer reaches all the internal parts of the engine.

3. Change the oil: Changing your engine oil before the winter season is a must as it keeps the engine running smoothly and ensures that it stays lubricated during long periods of inactivity. Follow the manufacturer’s recommended oil changing procedure and use the specified oil viscosity for your engine.

4. Flush your cooling system: Before winter storage, flush out the cooling system with fresh water to remove any salt, dirt, or debris that may have accumulated during the summer season. This will prevent corrosion and keep the engine cooler, thus prolonging its life.

5. Disconnect the battery: Disconnect the battery cables and terminals to prevent any self-discharge or short-circuiting during storage. Store the battery in a dry location, away from extreme temperatures or direct sunlight.

6. Cover your engine: Use a high-quality cover to protect your outboard motor from the elements during winter storage. A cover that is water-resistant and breathable will prevent any moisture buildup and keep your engine clean, dry, and dust-free.

Running an outboard motor during winter requires more attention to detail than during other seasons. But with these tips, you can take the necessary precautions to keep your outboard motor safe and running efficiently throughout the winter season. Happy boating!
