    MERCURY SMARTCRAFT ISSUES

    I came out to take my boat out and out of no where I'm getting no of my smartcraft gauges are working. The system says no tach found... what can te problem be?? The boat stil starts and both engines run. I had the marina check the wiring harness from the engines and all seems fine. Any help would be great. Thanks everyone

    Try unplugging the Tach at the tach, and at the Junction Box. Likely a lost connection (unless the Tach has been scrambled by lightening, etc).
