We bought a perfect shape 89 bayliner 2.3 omc cobra and was told that it was oer heating. The engine cranks and we car not getting a spark from the coil pack. we had the coil tested and it is good. Is there a kill switch or something that will have to be engaged before the boat will fire. This is are first bayliner and not sure where it would be if there was. The is a push switch that the label has come off, but not sure if thay is it. thanks
