Have a 2009 ProStar 197 and the gauges keep turning on and off, similar to when the ignition is turned on. Any suggestions on why or what might be going on? Could it be the MMDC going bad? If so why would it be going on on a 2009 boat???

Possibly a bad ground connection. Start at the battery. Then check where it connects to the engine. Trace the ground back to the dash. Good luck.

Mine is at the dealer right now for the same thing.

I am curious about what you find out. Mine do the same but it was after my subwoofer bounced out of place under the dash on a rough day. I assume it broke a connection somewhere but I can't find it. There are a lot of wires under there!
