Oil/Gas Mixture for a 1956 Evinrude

[FDenny]

What is the proper mix for this vintage motor. The gas can that came with the old motor says 1 qt per full tank 20:1. This tank was rusty and I was able to find another used newer tank ( 2 line system) and it says mix 50:1. I would assume the 20:1 is proper but just want to be sure.
But after thinking 1 qt per tank may be US gallons an would be approx 6 gallons. This mixture would be 24:1. Canadian or US I still need the proper mix.

It will be happy with TCW3 @ 24:1.

I've never been let down going 32/1.

Try the semi synthetic or synthetic, they smoke less. Rick

That engine calls for 24:1 ratio. One quart TC-W3 oil to 6 US Gallons petrol.
