The switch is good, both of them actually. The wiring is hard to find because it's an insulated bundle. It's been so dang hot here in Mississippi, I haven't been up for taking the time to trace it down yet. I have no idea where the wires run at this point.
I have an old 3.0L Mercruiser Alpha One. I recently replaced the carb and although it ran much better, I found shifting back into neutral almost impossible in the water. (This made for quite the adventure on a boat ramp with a lot of water current.) Anyway, I got home and tested the shift...
