I am wondering if someone could help me idenify the year of my 85hp Evinrude. I found some numbers on the side of the cylinders: "310532" then "2D" under that set of numbers. It is electric shift. Hood says Electric ignition and 85 on front, and Starflite on back. It is a V-4. Color is white. Also, does anyone know where to look for a book or a web site on idenifying outboard parts/motors? Any help would be appreciated.
