Hi,<br /><br />I just bought a 120 HP V4 evinrude (supposedly a 1991) serial number is: M or W (unreadable) 1738847<br />Model number either: Bl or BE and then b2011cca<br /><br />I went to the Evinrude site(Ken Cook) but I can't find anything that matches my info. Is there anyone who does know what this could or should be?<br /><br />I need them because I want to find out What sparkplugsand I would like to know how old my engine is.<br />thanks
