I have a 2007 Monterey 268SS, 8.1 Volvo and the power just shuts completely off randomly. It has done this while cruising as well as while idling along. After about 15 - 30 seconds the power comes back on and the boat starts and runs perfectly. It is doing this more frequently. I have checked the battery connections and replaced the kill switch lanyard. Does anyone have any other ideas as to what the issue may be. Thanks!

I have a 2007 268SS. The hour meter that is in the face if the tachometer has stopped working. Can this be repaired or will I need to replace the tachometer ?
