Just picked up a little motor tonight. Its an Evinrude 5.5hp fisherman. I got it running but want to know the year for ordering parts. Ive done some research and came up with it being a 1956 but I want a second opinion. The only #s Ive found so far is on the frost plug lookin thingamajobber. They are 5512 05607. Your help would be much appreciated. THANKS GUYS.
