Fuel mixture ratio for Yamaha rt100?
32:1
100:1
32:1
Most all models of Yamaha outboards can be operated on a 50:1 fuel to oil ratio.
I have a 1983 IT175 Yamaha and the fuel mix is recommended by Yamaha at 28 to 32: 1 I use 30:1 ratio. Hope this helps
32:1 ratio
The 1984 model, 200 hp Yamaha requires a 50:1 ratio.
50:1
oil ratio is 1% Pierre
i have ran 6ounces of 2 cycle oil to 1 gallon of gas
Around 32:1 depending on the quality of the oil.
