Thanks bobeast, I will try it as soon as I visit my boat!On the rear of the engine is an electrical "umbilical" cord that looks a lot like a trailer connector. That cord carries all of your gage signals. I had a problem with an intermittent tach that I solved by unplugging that cord and cleaning all the pins in the connector. worth a shot.
