three Questions <br />I just got a Mercury 4 hp for free, serial # 7120417, want to know what year is it?<br />What plugs are recommended? and gap<br />Starts good know but bogs close to full throttle, any suggestions?<br />Thanks
Looks like a 76-79 but Im sure the Merc experts can tell you for sure. You might try posting in the Merc section for better response.<br /><br />Good luck!
