Mercruiser MCM 165, ser. no. B648337. I'm trying to troubleshoot dead battery problem. Seller said it happened to him a couple of times recently. I bought a brand new battery. It too went dead after a couple hours of motoring around the sound.
I measured around 17 volts at the battery at idle and 2000 rpm. Is that kosher? Too high? My SELOC manual is lacking in these kind of details.
Any other hints for why a new battery would go dead, besides the obvious (loose wiring or corrosion)?
BTW, before I drop another $80, is the Mercury #8 manual a lot better than the SELOC manual? I wasn't terribly impressed with it. I can do anything, practically, with a Haynes manual including remove and rebuild an engine, but I thought the SELOC glossed over things too much. Any opinions?
