1972 Evinrude 25 HP, Oil / gas ratio recomended

[BBMAXX]

Not sure what ratio of oil/to gas to use. And is this considered a 2 or 4 stroke engine. Thanks, Brad

bb, <br /><br />It's a two stroke.<br /><br />Ratio is 50:1. One pint of TCW-3 rated two cycle oil to six gallons of 87 octane unleaded gasoline.
