The oil ratio for a Johnson 4R69B outboard motor, which is a 4 hp model, is typically 50:1. This means you should mix 2.6 ounces of two-stroke oil with one gallon of gasoline. Always use a high-quality oil designed for air-cooled two-stroke engines to ensure optimal performance and engine longevity. Always consult the owner's manual for specific recommendations and verify if there are any variations based on the motor's condition or operating environment.
