How To Fog A Outboard Motor

How to Fog an Outboard Motor: A Comprehensive Guide

Maintaining your outboard motor is crucial for its longevity and performance. One vital step in this process is fogging, a crucial procedure that protects your engine's internal components from corrosion during periods of inactivity. This guide will walk you through the process of properly fogging your outboard motor, ensuring it's ready for action when you are.

What is Fogging?

Fogging an outboard motor involves spraying a specialized fogging oil into the engine's intake system. This oil coats all internal parts, creating a protective barrier against moisture, rust, and corrosion. This is especially important during off-season storage or periods of extended non-use. Without fogging, your engine's vulnerable internal components are at high risk of damage.

Why Fog Your Outboard Motor?

• Corrosion Prevention: Moisture is the enemy of metal. Fogging prevents moisture from accumulating and causing corrosion on critical engine parts.
• Extended Engine Life: Protecting your engine from corrosion significantly extends its lifespan, saving you money on repairs or replacements.
• Peace of Mind: Knowing your engine is properly protected gives you peace of mind during storage, knowing it'll be ready to go when you need it.
• Smooth Startup: A well-fogged engine often starts more easily in the spring, compared to a neglected one.

What You'll Need:

• Outboard Motor Fogging Oil: This is crucial. Do not use regular motor oil. Fogging oil is specifically formulated for this purpose.
• Fogging Oil Spray Can (or Pump-Style Fogger): Choose a delivery system that works for you.
• Gloves: Protect your hands.
• Safety Glasses: Protect your eyes.
• Rags: For cleaning up any spills.

Step-by-Step Guide to Fogging Your Outboard Motor:

1. Prepare Your Engine: Ensure the engine is off and cool. Disconnect the battery to prevent accidental starting.

2. Locate the Fogging Oil Inlet: This is usually near the air intake or carburetor. Your owner's manual will show you the precise location.

3. Connect the Fogging Oil Spray Can: Attach the can to the inlet.

4. Start the Engine: Crank the engine, ensuring it's running at a fast idle speed.

5. Spray the Fogging Oil: Begin spraying the fogging oil into the engine's intake. Continue spraying for the duration specified by the manufacturer on the fogging oil can. This is typically between 10-15 seconds.

6. Let it Run: Let the engine run until it stalls, as the fogging oil displaces the fuel and coats the internal components.

7. Disconnect and Clean: Remove the spray can from the inlet and carefully clean any spills.

Post-Fogging:

• Storage: Once fogged, store your outboard motor according to the manufacturer's recommendations.
• Re-starting: When you're ready to use your motor again, you'll likely need to run it for a bit to burn off excess fogging oil before normal operation. Your owner's manual will have details.

Important Considerations:

• Consult Your Owner's Manual: Always refer to your outboard motor's owner's manual for specific instructions and recommendations. The process may vary slightly between different motor models.
• Use the Right Oil: Using the wrong type of oil can damage your engine.

By following these steps, you can effectively protect your outboard motor from corrosion and extend its life. Remember, preventative maintenance is key to keeping your outboard running smoothly for years to come. Proper fogging is a simple yet powerful way to ensure your engine is ready for its next adventure.
