Here's a
link that should answer many of your questions. Here's
another link with a lot of good info. Battery group really only refers to dimensions, important for automotive applications, but not so much on marine stuff. Deka also had a marine applications link where you just look up the cranking amps for brand, and size of motor, but can't find it today for some reason. I think the requirements for a carb'd V-6 are generally about 800 CCA, but I'm sure you can get by with less. Separate starting and deep cycle batteries with a selector switch and/or and ACR is the optimum setup.
