Could anyone tell me what year my Evinrude Lark X 40 hp is and proper oil to gas ratio and any other specs on this motor. Model# 40063a Serial#E01773 Thanks.
i think, if your numbers are actually model #40053, it is a 1970 .... 50:1 is the oil mix...<br /><br />check the old omc site<br /> http://mitglied.lycos.de/old_omc/
