Five hp Gamefisher air cooled motor
Last fall I was given a 5hp Gamefisher air cooled outboard. It was sold by Simpson Sears. Today I dug it out and tried to find the gas/oil mix but had no luck. It is probably 20-30 years old, in very good shape but there doesn't seem to be any serial number or other details. I figure I will try 40:1 synthetic mix with high test gas unless anyone has a better idea.....

32:1and use an oil designed for air cooled engines as compared to tcwIII which is designed for the lower operating temps of liquid cooled engines.

These were made for Sears by Eska using Tecumseh motors. Agree use 32:1 and hi test.

Sounds like my 40:1 chain saw mix should be pretty close...

Should be close enough. Make sure you run premium. Also, if you need parts, I have half a dozen of these things.

According to the manual the mix rate is 20 to 1. I usually go at 30 to 1.

Now it's air cooled oil in hi test gas....my old Elto wouldn't recognize a modern diet......
My first outboard was a 1958 18 hp Evinrude electric start. It was 24:1, 1 quart of SAE 30 to 5 imp gallons of gas

My 1955 johnson seahorse says 20.1 on the fuel tank with 10w30 oil LOL
Always ran 91oc at 40.1 with shell 2 stroke marine oil. Oil is a lot better now a days, I dont think theres a need for any richer than 40.1 unless it really tired
