Hi all:<br /><br />I recently came across some Merc motors. Can anyone tell me what year they are and what gas
il mix would be appropriate? Also, what spark plug do they take?<br /><br />First motor: Merc 110, 9.8-hp (serial # 2074924 or 207492A or 207492H - couldn't make out last character).<br /><br />Second motor: Merc 7.5-hp (serial # 3373225)<br /><br />Thanks in advance.
