Thank you both for your replies!

BH, I never run the boat with the battery switch on BOTH. There's a warning on the switch telling me that doing that will burn out the alternator. That's enough of a warning to keep me from doing that! I checked when I bought the boat and was told by Channel Marine's mechanic that the bilge pump is powered even when the battery switch is off. I've seen evidence of that in my driveway after a heavy rain if I neglected to pull the transom plug when I got home.

JRC, yes, we always switch back and forth on the batteries with each use of the boat so I agree, two marine starting batteries would probably be best given your's and BH's examples of usage. I can live with the shorter battery life at anchor because, theoretically, I'll have the other battery to start with if I actually drain the first one on any given day at anchor.

I think I'll pass on the isolator idea; why complicate things when I don't have to? I'm sure it's a great idea in the right situation, I just don't think I need it in my situation.

Anyone have any thoughts on my radio issue? Is it possible the radio is wired to battery 1 regardless of which battery I'm switched to run on on any given day?
