How To Winterize An Outboard Motor- Everything You Need To Know

Introduction

Winterizing your outboard motor is crucial for maintaining its performance and longevity during the off-season. This guide will walk you through the essential steps to properly winterize your outboard motor, ensuring it remains in excellent condition when boating season returns.

Step 1: Change the Engine Oil

• Replace old engine oil:
  • Old oil contains contaminants that can damage your engine over time.
  • Use the manufacturer-recommended oil type.
  • Warm up the engine slightly to help the oil drain more easily.
• Drain the old oil:
  • Locate the oil drain plug and remove it.
  • Allow the old oil to fully drain into an appropriate container.
• Fill with new oil:
  • Replace the oil drain plug.
  • Pour in the new engine oil using a funnel to avoid spills.
  • Check the oil level with the dipstick and add more oil if necessary.

Step 2: Change the Gear Oil

• Locate the gearbox:
  • Find the gearbox near the propeller.
• Drain the old gear oil:
  • Remove the drain plug and let the old oil drain completely.
• Refill with new gear oil:
  • Replace the drain plug.
  • Use a pump to fill the gearbox with new gear oil until it reaches the fill hole.

Step 3: Stabilize Your Fuel

• Add fuel stabilizer:
  • Pour the recommended amount of fuel stabilizer into your fuel tank.
• Run the engine:
  • Start the engine and run it for about 10 minutes. This allows the stabilizer to circulate throughout the fuel system.
• Top off the tank:
  • Fill the fuel tank to the brim to minimize air space and reduce the chance of condensation.

Step 4: Fog Your Engine

• Prepare fogging oil:
  • Purchase fogging oil specifically designed for outboard motors.
• Spray fogging oil into the cylinders:
  • Remove the spark plugs.
  • Spray the fogging oil directly into the engine's cylinders.
  • Reinstall the spark plugs.

Step 5: Inspect Your Propeller

• Remove the propeller:
  • Use a wrench to loosen and remove the propeller from the shaft.
• Check for damage:
  • Inspect the propeller for any dents, dings, or bent blades.
  • Replace if necessary or repair minor damages.

Step 6: Store Your Outboard Motor Upright

• Drain any remaining water:
  • Store the motor in an upright position to allow any residual water to drain out.
• Protect from the elements:
  • Consider using a motor cover or tarp to protect it from moisture and debris during storage.

Conclusion

Winterizing your outboard motor is a straightforward process that involves changing oils, stabilizing fuel, and ensuring proper storage. By following these steps, you can help extend the life of your motor and ensure it’s ready for use when boating season resumes. Consider setting a reminder to perform these winterization tasks annually to maintain your equipment in top condition.
