As someone who cranked Big Fours in high school, I considered electric starting an unnecessary luxury. In those days put Speeditwins and Bigtwins on and off the boat with only minor discomfort. Now I no longer consider Lightfours light and find Zephyrs challenge. I find all things get heavier with age . . . I cannot remember any OMC part like that. but will not say it is impossible. Know that many useless pieces of equipment are found in Preowned Merchandise Emporiums (AKA Junk Yards) that most people view as useless. Still most homes have a “Junk drawer” for such stuff. It is usually tossed while Spring cleaning just prior to finding a good use for it. . .
