Ahoy, Joey.<br /><br />It would be best to know when the engine was made, as Hooty asks.<br /><br />As a (very) general rule, engines made before about 1970 usually used a 24:1 mix. After that, 50:1.<br /><br />Because I don't remember ever seeing an Evinrude-made Sears engine I think it probably falls into the 24:1 era.<br /><br />Red sky at night. . .<br />JB :)

Hi there Joey!<br /> Hooty & JB are right we need numbers on the motor to get the year & who manufactured it. JB is right in that Evinrude {OMC} did not make it. My info shows that West Bend,McCulloch,Clinton & Eska were manufacturers of Sears over the years so the fuel/oil ratio will vary quite a bit.<br /> Note: this is the best marine info forum I have ever come across. Yknot.
