i´ve got an merc 300M 35hp ´63 or ´64<br />s.no:1352979 (straight 4-cyl)<br />and my problem is the oil/fuelmixture.<br />Should it be 4% or what?<br />With modern oils, do I need that much oil?<br /><br />Second question, does anybody know where to get props to that engine?<br />(There´s no exhaust in the propcenter)<br />Hope to get a quick answer from anyone who knows about these old engines...<br /><br />------------------

50:1 with a good quality modern outboard oil is fine.
