Help! Put my 2000 in the lake for its first outing of the year. Everything was going fine. Water temp fine. Oil pressure fine. Voltage fine. RPM fine. Then, lost all gauges. Horn and radio still function and boat runs without issue, but no tach or speedo. Disconnected battery, and reconnected. Nothing. Normally, when turn key half way, gauges "energize". Now, nothing. Any ideas are greatly appreciated.
