Most all models of Yamaha outboards can be operated on a 50:1 fuel to oil ratio.
Shop Manual says 50:1
32:1 is standard fuel mixture for 2 stroke engines, you can use different ratios but this is the reccomended ratio by the manufacturer.
According to yamaha, it's 32\1 or 40/1.
Fuel mixture ratio for Yamaha rt100?
The fuel and oil mixes by itself. Why would you need to do it yourself.
one liter fuel 10 mill oil
The 1984 model, 200 hp Yamaha requires a 50:1 ratio.
Yamaha has been oil injected since they began. If you need to mix yet, run 50/1
oil ratio is 1% Pierre
The. Mix is 20 to 1 it will run well on that. With 91 octane gasoline
