Stick with a "marine rated" battery. It's safer. Also if its a wet cell type make sure it's in a compartment vented to the exterior:p

The spacers between the plates are designed different. Using non marine batteries in a marine application will result in problems from early battery failure (shorted/dead cells) up to catastrophic failure (GO BOOM). Along with the problems of loss of warranty and or loss of insurance coverage.:p

Have you considered a generator? All that draw for a full day is beyond the scope of just about anything marine. As was said, you could rig in a towmotor battery but when it fails and explodes from the bouncing that a boat gets, don't expect your insurer to take your calls.

I've also heard golf cart batteries are the way to go.
