Went out this AM and about an hour and a half into the morning, my RPM gauge and PP started freakin out. The RPM needle started jumping around and the PP, while not in use, started beeping and flashing at me. The boat kept running normal, temp good, oil pressure and battery was all normal. The stereo was on but turned down way low. The RPM gauge and PP finally flat lined and shut off then the stereo started popping on me and it shut off.
When we got back to the dock I shut the boat off and tried to re-start and nothing!
I am sure the battery is the culprit but should I be concerned with anything else?
Boat is an '05 Malibu Wakesetter 23 LSV and the PP unit is factory installed.
