I just noticed today that the hourmeter in my boat seems to have stopped working. The hours still show, but the 'hourglass' is not flashing and the hours are not being recorded. I tried turning the boat on and off but no change. Any ideas on what could have caused this to happen, and how to repair this? I realize some may see this as a 'good thing' but I would prefer for the hours to remain true Thanks for your input!
