I have 50hp Mercury that runs good. The tach reads at idle but as you accelerate it turns counter clockwise at a rate that seems to match where it should be but backwards. Anyone have any thoughts?
only really 2 things possible
bad tach or bad rectifier regulator

Thanks, I’ll google how to test the rectifier.
