The fuel mix for an 8HP Yamaha outboard engine typically requires a 50:1 ratio of gasoline to 2-stroke oil. This means you should mix 2.6 ounces of 2-stroke oil with one gallon of gasoline. Always refer to the owner's manual for specific recommendations, as mix ratios can vary slightly between models and manufacturers. Using the correct fuel mixture is essential for optimal performance and engine longevity.
