I'm currently trying to bring my 23.5 back to its original configuration and have a couple questions about the battery. First, does anyone know what the recommended battery was for this vessel. The PO (previous owner) of my boat had two huge size group 31 batteries stuffed into the right side bilge well (I believe the original location) and under the galley sink. Yes, this one was a bear to get out as it must weigh about 70 pounds. The PO did a wonderful job of securing these batteries. Unfortunately, the trays were secured with screws that were at least one and a half inches long, two of which went through the hull and another five through the ballast tank. I've since repaired the holes with some good ole 5200. Back to the original gripe er, question, Looking at the original battery support, it seems a little small, even for my planned single size group 24 battery. Could someone post a picture of this area with and without the battery installed? Does anyone know what size battery was originally recommended? Could I add a layer of epoxied wood to provide a wider (and thicker) base for the battery tray? If anyone else has made upgrades to the battery, I love to hear about it or see pictures.
