Ssobol, There are several other differences, and one is that the AWG is thinner wire strands, so less likely to break under stress. I happen to use all marine cables--because I have it in my shop--lots of pieces from past projects. (My wife threatens to get a dumpster for my hoarding boat parts!).
I have seen some auto cable (as well as marine) which corroded, and broke.
Salt is more corrosive, but so is fresh water. Keeping connections, and well supported with adhesive shrink wrap is important in all cases. Unfortunately, most auto part stores are not adhesive shrink wrapped.
The other argument, is though you will only use the boat in Fresh Water, the next owner may not-(and VA has some fantastic salt water areas!)
On the other hand a lot of folks use welding cable--again there are mixed review. The wire is finer, but often breaks down, and my feeling is that the insulation is not as good in many cases (also holds true for auto).
Buying from a good supplier is important. We do have one of the wholesale suppliers in Pensacola, and I had never thought about setting up a way that we could get OEM prices…I may look into that when I get home. The Australian distributer stays with us when he is in the US, about once a year.
