What is the fuel ratio for a 2-stroke outboard motor?

2-STROKE OUTBOARDS (CARBURETED) During the break-in period you should use a 25:1 oil/fuel mixture (1000 mL of oil for every 25 liter of gas). See our oil/fuel chart for more info on the 50:1/25:1 ratios. Tohatsu 2-stroke outboards use TCW3 oil which is specially formulated for 2-stroke outboards.

What is a 50 to 1 fuel mix?

How much oil to mix in a 5 horsepower motor?

Divide the number of gallons by the mix ratio for the motor use. While a 5-horsepower motor is unlikely to be subjected to racing conditions, the racing mix is 25 parts gasoline to 1 part oil–a full 5-gallon container, 640 ounces, is properly mixed when you add 26 ounces of oil: 640/25=25.6, or 26 ounces. How do you mix 2 cycle oil on a boat?
