Looking for ideas and where to place another battery. My 86 offshore with twin yamaha's is already a little stern heavy. I want to add a group 27 house battery strictly for house loads. I currently have 2 group 24 batteries in the bilge 1 for each engine.

My 241 Offshore has a giant space under cockpit floor I think is for a second fuel cell. Wonder if that may be a feasible location if yours is the same?
that spot currently houses my fuel tank. I don't have the second fuel tank. I was thinking of moving all the batteries into that space but then that would require unsealing the deck plate if i would need to get in there at the batteries

Mine is an I/O, and fuel cell is towards helm area. Is yours towards stern? If so, I've seen several pics where people hinged the cover to use the forward area for storage. A few of them are are on this forum.
My fuel cell is at the helm area. My boat also has twin outboards so i have the extra fuel cell area but no tank was ever installed. Below is a pic of my deck i was thinking of moving all the batteries to where the second fuel cell would be. That would free up some weight from the stern. I like the idea of hinging the deck plate got any pics?? Ypu can c where the fuel hoses are on the right. That is where i was thinking of putting all 3 batteries
Also the distance from where i want to place the batteries is 8 feet. I have enough 6 gauge battery wire left over from another project. Would that be ok to use? The engines are 1987 yamaha 150 2-strokes. From what i found out the alternators put 25 to 30 amps max.
I see your tank is in the same area as mine. are your outboards mounted directly to a notched transom, or do you have an enclosed transom? Reason I ask is that if you have the notched transom, every now and then a large amount of water can come over it into the cockpit. If you hinge that rear cover area, that could create inlet for water entering bilge in large amounts. I recall one time far offshore when I was in dire straits in a 22' Seafarer with notched transom. Waves were breaking over the bow for considerable time, and cockpit floor was swamped for hours and drains could not keep up with water coming in. At times it was so bad water poured out of boat over the transom notch. If I would have had a hinged floor cover in that boat, I would not be here to tell you this. Just food for thought.
I have a full transom that is one of the reasons i bought the boat. I'm planning on using that space also for 30 gallon fresh water tank and mounting the raw and fresh water pumps in there as well. I could also install a bilge pump if need be. I will probably just install everything in there and seal the hatch again. If i have to get in there i just have to cut the seal and remove the screws
