But if you do install the "add a battery" kit. Why are you touching your boats wiring??
On a boat that small, I don't think you house and starting load can be separated. Even if you could, why?
I will have two batteries. To me, the starting battery should only handle starting the boat and everything else should be ran off the house battery. That way if someone leaves my fresh water pump on (has already happened) or something else on the boat on, it is not draining the starting battery, just the house battery. A few weekends ago a friends kid had got on there and was messing around with all the switches. I came back on the boat and the blower, docking lights, and courtesy lights were all on.

That is exactly what the add a battery kit is, a switch and an ARC.
I keep seeing the Blue Sea Systems Add a Battery kit being recommended system as the preferred system to do what I want as you just have to keep the switch set to on and the systems is smart enough to isolate the batteries when not charging. When the motor is running it properly charges both batteries. Maybe I have that all wrong and I'm just not understanding what you are trying to tell me...
On understanding, forgive me but I have mentioned this twice.
On "That is exactly what the add a battery kit is, a switch and an ARC." No it is not as I have mentioned. You can not start your engine on ether battery alone. You must combine the two just to use the 2nd battery in stating. Which can discharge into the #1 battery and more...
And on "To me, the starting battery should only handle starting the boat and everything else should be ran off the house battery." So true. But hard to do on smaller boats since there not wired that way. But it can be done.
Also with the Arc I mentioned. By using the ground wire as a control you can turn it off and on. This is very useful with a on board charger.
Enough said as far as I am concerned, unless you have a direct question. Good luck..
