Just as bears prepare for winter by hibernating, you need to prepare your outboard motor to face the cold months ahead. You’ll start by draining the water to prevent any internal ice damage, which could be a costly oversight. But that’s just the tip of the iceberg. What follows includes treating your fuel system and changing oils, actions that ensure your motor kicks back to life effortlessly come spring. What might be less obvious, though, is the crucial step of fogging the engine—do you know why it’s essential, or how to correctly do it? Let’s explore these steps further and ensure your motor is not just stored, but thoroughly preserved.
Step 1: Drain the Engine
Begin by draining all water from the engine to prevent freezing and corrosion. This essential first step safeguards the heart of your outboard motor during the cold months.
You’ll want to focus on the motor’s cooling system, especially if you’ve been using your boat in saltwater or contaminated freshwater. Salt and contaminants can cause significant damage if they’re left to sit in the engine.
First, locate the drain plugs on your motor. These are typically found at the lowest points of the cooling system. Open these plugs to let the raw water flow out.
Don’t forget to check the water pump and its housing; water often lurks here and can be overlooked.
Next, flush the system with fresh water to remove any residual salt, dirt, or debris. This step is crucial as it minimizes the risk of corrosion and buildup inside the cooling passages.
After flushing, drain the water again thoroughly.
It’s also a good idea to change the engine oil now. Old oil can contain contaminants and moisture that might harm the engine if they’re allowed to sit over the winter.
Fresh engine oil will provide better protection against corrosion and ensure your motor is ready to go when spring arrives.
Step 2: Stabilize the Fuel System
Next, add a fuel stabilizer to your tank to prevent the fuel from degrading and protect your engine during storage. It’s crucial, especially if you’re not using ethanol-free gas, which is less prone to moisture absorption and phase separation. Pour the recommended amount of stabilizer into the fuel tank before filling it up with gas. This ensures the stabilizer mixes thoroughly with the fuel.
Once you’ve added the stabilizer, run your engine for about 10 minutes. This step helps the stabilized fuel circulate through the entire fuel system, reaching the fuel lines, fuel filter, and carburetor. It’s vital to ensure that every component of the fuel system gets treated, as leftover untreated gas can cause issues like corrosion or gumming.
Make sure to top off your fuel tank to avoid any space for condensation to form during the colder months. A full tank minimizes the air space above the fuel, reducing moisture problems that can lead to rust or contamination in your fuel supply.
Lastly, check the fuel line and connections for any leaks or wear. Replace any worn parts to maintain a tight seal and keep your fuel system in top shape for your next boating season.
Step 3: Change Engine and Gearcase Oil
After ensuring your fuel system is secure, focus on changing the engine and gearcase oil to maintain engine health over the winter.
Start by warming up your motor; this makes the oil less viscous and easier to drain. Locate the oil tank and remove the dipstick tube. You’ll want to carefully drain the old oil into a suitable container for proper disposal later.
Next, replace the engine oil. Pour fresh oil into the oil tank, ensuring you use the type recommended by the manufacturer for your specific motor model. It’s crucial to avoid overfilling; check the level with the dipstick to ensure it’s just right.
Now, shift your attention to the lower unit’s gear lube. To change this, you’ll need to locate the drain plug at the bottom of the lower unit. Remove the plug and let the old gear lube drain completely, which might take a few minutes.
After the gearcase is empty, refill it with new gear lube, ensuring it’s filled up to the level of the fill hole.
These oil changes aren’t just routine outboard motor maintenance; they’re vital for preventing corrosion and ensuring your outboard motor runs smoothly when you’re ready to hit the water next season.
Step 4: Fog the Engine
To protect your motor’s internal components during storage, fog the engine using a quality fogging oil. This step is crucial to ensure that your boat motor remains in top condition through the winter.
Start by warming up your motor to open the pores in the metal, making it more receptive to the fogging oil.
Once your motor is warm, remove the spark plugs and spray fogging oil directly into each cylinder. You’ll want to be generous with the spray to make sure you’ve got every angle covered.
After you’ve fogged the cylinders, replace the spark plugs temporarily and turn over the engine a few times without starting it. This helps distribute the fogging oil evenly across the internal surfaces.
Next, you’ll need to actually start the motor and let it run. While it’s running, spray the fogging oil into the air intakes until the engine dies. This ensures that every internal part of your boat motor gets a protective coating, helping to prevent corrosion during winter storage.

Step 5: Protect Electrical Components
Having safeguarded your motor’s internal components, you should now focus on protecting its electrical systems from moisture and corrosion. During winter storage, the electrical components of your boat engine are vulnerable to damage from cold weather, which can lead to costly repairs come spring.
Start by consulting your owner’s manual to locate and identify all electrical connections on your motor. Once you’ve got a clear idea of where everything is, disconnect the battery. It’s essential to remove the battery from the boat and store it in a cool, dry place. This prevents the cold from draining its charge and reduces the risk of corrosion.
Next, apply a moisture-displacing lubricant to all electrical connections, including terminals and wiring harnesses. This step is crucial for keeping moisture out and ensuring that your boat engine’s electrical components don’t succumb to rust or corrosion. Follow the manufacturer’s instructions closely when applying any products to ensure you’re using them safely and effectively.
Lastly, once all connections are treated, cover the engine properly to shield it from dust and further moisture ingress. This additional layer of protection helps ensure that your boat engine remains in top condition throughout the cold storage period.
