Oil/Gas Mixture for a '73 Evinrude

[loopit]

I have a 1973 6 HP Evinrude motor and I was wondering what oil/gas ratio to use. I've heard 32:1, 40:1, and 50:1. Which is it?<br /><br />Also, I have a 6 gallon tank. Is there an easy way to tell how much oil to put in the tank? Such as one or two pints of oil for every full tank?<br /><br />Jeff

50:1 One pint quality 2 stroke oil to 6 gallons of regular gas.<br /><br />Bob

Is it better to use 93 octane or should I stick with 87?<br /><br />Jeff

Hi Loopit,<br />Try 3oz. per gallon that will be real close to 50:1 It also helps when you arn't putting in a full 6 gals.
