Greetings, folks. I'd like to learn what year my Evinrude 5.5 Fisherman is, and I'm guessing from reading old postings that the serial number is a clue. Mine is 5518-07677. It's a blue & white engine cover. I'm definitely not a mechanic, but I'm interested in bringing it back to life. It's probably from the mid to late 50's. If someone can point me toward the year and maybe a suggestion for a repair manual, I'll be grateful. Thanks much.
