Eagle 175 17.5 ft 40lb trolling motor.

Ok guys, the trolling motor is too small. Will be upgrading. I can go with a edge 55 but I know if I would go with a 24vdc unit it would be better. I have no room to put a third battery in the back and I really haven't looked at moving anything upfront because the only place would be in the rod box.

This is my question, I could series the batteries and then put the motor on one battery which would still be 12VDC. Electrically it will work. But I'm worried about draining the starter battery.

Has anybody done this. All thoughts appreciated.
