New Troller motor & 2 marine batteries

New Minn Kota 55lb thrust. Never hooked up. Have all paperwork and receipt from bass pro. Bought in April. Also 2 Deep Cycle bass pro marine batteries. Same as above receipts etc. I never hooked them to the boat. I bought a boat off Craig's list, and it didn't have motor. Reason for the troller motor and batteries. I pd $239. Motor $130. Each for batteries. $500.Plus tax. Bass pro doesn't take these type of items back apparently.
