Winterizing a 9.9 Evinrude Outboard Motor, Part I

Winterizing an Evinrude 9.9 outboard motor may seem expensive, but failing to do so will cost more in the long run. Begin by washing the motor. Next, add one ounce of fuel stabilizer to the tank for each gallon of fuel the tank can hold. Run the mixture through the engine.

Flushing attachments, sometimes referred to as “earmuffs,” should be attached to a garden hose. Cover the motor’s cooling water intake with the earmuffs. Run the motor at 1500 rpm for five minutes. Stay tuned tomorrow for Part II of winterizing a 9.9 Evinrude outboard. Keep in mind that as it’s still summer, so continue using Evinrude oil to keep your boat humming along for the rest of the season.
