im my opinion, 2 batteries are a must and they will charge each other when both are used at the same time.
If I have them set correctly, one battery starts 1 of the engines of the boat, the other works the electronics and the second engine. If I forget the electronics on and kill the battery, I only kill 1 battery and not both, so I always have a one battery back up.
Too confusing. For Turbo Dan (and myself) the Yandina combiner is the way to go. Cheapest, easiest and most reliable solution.He can always add an on/off switch between battery(s) and the house circuits if he wants ( I am not going to bother).Just one more thing to get in the way.

Only problem is that there's only space for one battery in my boat. The battery's in one of the stern consoles, next to the oil canister. Can you have one battery back there and one, say, in the center console?
the way they set mine up is confusing, I will show you this season. Usually you have 2 batteries with 1 switch.. I have 2 switches. If I have them set correctly, one battery starts 1 of the engines of the boat, the other works the electronics and the second engine. If I forget the electronics on and kill the battery, I only kill 1 battery and not both, so I always have a one battery back up. If I was to put both sets of switchs on ALL, they both will charge together with the alternator, when the engine is running. If I put the first set of switch on ALL, I still won't be able to access the second battery unless I put that switch on battery 1. Remember, its like nothing I ever seen before, so I am sure you can use the basic rule that your stating, out of the question.

I get confused with were I should put the switches. I usually leave them on both, Which I know drains both the batteries when the engines aren't running. That is why I carry a jumper pack all the time. How ever Mike, I looked at the wiring diagram for a dual engine/ dual battery setup with the combiner and they show several switches in the system. This is confusing to me. How does this work?
