Hello, could someone help me with the recomended mix of oil for a 50hp Mercury from 1979 or 1980 # 9248919.<br /><br />Can I find out the year of manufacturing from the serial number?<br /><br />Thank you!
Yes...the serial number will reference the year. Unfortunately, I don't have that info at this time...sorry. Your engine should run fine on a 50:1 oil/fuel mixture.<br /><br />Walt
