  3. Additional Recommendations



To prevent injury from contact with rotating propeller, remove the propeller before flushing.

DO NOT start outboard without a water supply to the outboard's cooling system. Cooling system and/or powerhead damage could occur.

Fuel System Treatment

Stabilize the boat's fuel supply with Evinrude/Johnson 2+4 Fuel Conditioner following the instructions on the container.

Prepare a "storage mixture" of fuel in a separate outboard six gallon fuel tank. The storage mixture should consist of:

  • 5 gallons of fuel

  • 2 quarts of Evinrude/Johnson Storage Fogging Oil

  • 2.5 ounces of Evinrude/Johnson 2+4 Fuel Conditioner

  • 1 pint of Evinrude/Johnson outboard lubricant

START outboard and RUN at IDLE speed for five minutes to ensure that the entire fuel system is filled with the storage mixture.

Proceed with Internal Engine Treatment.

Internal Engine Treatment

Check level and condition of crankcase oil. Change oil and filter if required.

Use Evinrud/Johnson Storage Foggin Oil to prevent corrosion of internal engine components during periods of storage.

Remove spark plugs and spray a liberal amount of Evinrude/Johnson Storage Fogging Oil into the spark plug holes.

Turn the flywheel in a clockwise direction to distribute the fogging oil throughout the cylinders. Install and torque the spark plugs.

If outboard is equipped with a portable fuel tank, disconnect fuel hose from outboard and tank.

DO NOT restart outboard until it goes back into service.

If the outboard is removed from boat, examine all loosened and removed hardware. Replace damaged or missing parts with guenuine Evinrude/Johnson parts or equivalent.

Additional Recommendations

  • Replace gearcase lubricant.

  • Remove and inspect propeller.

  • Clean and grease propeller shaft.

  • Lubricate all grease fittings and linkages.

  • Clean or replace fuel filter element.

  • Inspect outboard and controls. Replace all damaged and worn components. Refer to manufacturer's maintenance and lubrication recommendations.

  • Touch up painted surfaces as needed. Coat outer painted surfaces with automotive wax.

  • Store outboard in upright (vertical) position.

  • Check for fuel leakage.

Failure to check for fuel leakages could allow a leak to go undetected, resulting in fire or explosion.
