I have put a lot of time into this project. But I know this motor with a 9 pitch prop is spinning way to fast. But I cannot find a Tach for a two cylinder mercury 9.9. Does anyone know if they make them? Also which model is a 6.5 inch cut out. Got PVC to drop in that size tach. Thanks:cheers:

Tiny Tach, one wire to ground, the other wraps around the spark plug wire
