I removed my other reply because I misread the comments.

If you have two batteries that you are trying to wire to your trolling motor while maintaining 12v you need to wire them in parrallel.  Hook a jumper from POS to POS and then a jumper from NEG to NEG.  Then power supply to your TM will be wires from trolling motor to NEG and POS on the same battery. 
This will give you the SAME AMPS AND THE SAME VOLTAGE.
If you just add a jumper from one battery to the other you will be supplying 24v to your TM, thus smoking it
