[Bruce Heyman]

Don,
Conventional wisdom is you should replace both batteries at the same time, preferably from the same manufacturing run.

I tried disconnecting each battery individually, to determine which wasn't providing power by using the battery selection switch on the electrical panel. I guess both batteries are on the same power bus because, no matter which one I disconnected, it shut down ALL power no matter which battery position was selected. Anyone know which battery (No. 1 or 2)is the forward battery in the earlier boats (hull 53/1994), and how you  make that determination? Thanks much.
