34 ft Californian I just acquired has two 8D batteries in an impossible place in the boat. Outboard of the port 3208N engine. They look pretty bad, neglected, and how old I don't know, nor did the POwho didn't use the boat much. One is said to be for start and the other house. One perko switch with 1, 2, both, and off positions. Don't live aboard nor spend more than a weekend at sea. Have a generator and will remove the ice maker and probably the refrig--just use ice chest so demand on house battery isn't great. Have*been told*that multiple 27s or 31s could be used.* I think I understand that wired in parallel you get max cranking amps and in the case of 6 volts wired in series gets 12 volts. Is that correct? For the 3208NAs would two 27s in parallel be sufficient. I'm in Florida so only have a few cold days in the winter and our use would be minimal during Jan. and Feb.* 70 degrees out there now. How about two 27 deep cycle for the house side?*Have seen*opinions that*the wet cell seem sufficient considering cost difference compared to gel etc. Also Advanced Auto got a plug for their batteries.

I considered moving the battery location but that would require a lot of new wiring and not sure where I would put them. Considered the 6 volt batteries but they are pretty heavy as well so would like to stay with 27s or if necessary 31s. Your thoughts on size of battery, type, and brand name. Thanks
