12/24V Trolling Motor Wiring

I have a 12 volt trolling motor in my Skeeter. I was confused when I looked at the wiring because it appeared that they were connected in series for a 24 volt. I checked and did find out it was 12/24. However, I want to just wire it for 12 volt, and hook 2 in parallel for it. Can I do that with that setup? Is it just a matter of disconnecting the 24 V lead, and going from the 12? Any help would be greatly appreciated.
