My neutral safety switch went bad ( not shift interrupter switch ). It's intermittent on an ohm meter causing boat not to start. Jump it and it runs, hook it back up and no go. Obviously bad. 1980 Bayliner Eagle 350/ 260 Mercruiser. Question is, Have the switches used over the years been pretty common ? or has every manufacturer used something different. Going to dealer Monday hoping to find the switch, just looking for a possible answer and hoping to not have to buy a new shift control. Don????????
