I bought a 15 hp Evinrude at a garage sale. It is a model number E15RCTA, serial number E0203720. What year could this be? What is the best manual to buy if I want to try to get it running? <br />I also bought a "SeaKing" 3 or 5 horse that needs one of those ropes that you wrap aroung the top to start it. Does any body still sell these things? (This engine actually starts, though I need to figure out what sort of gear oil to use in the lower parts)<br />Thanks.
