Thanks for all the info. Previous owner said 5 hours max as set up. And he would bring 2 extra batteries to finish out the day.

I have 2- 31 batteries from Walmart on a 24 volt Terrova and can pull cranks for 10 hours and have some left.

Not all batteries are created equal, not sure of the brand you have now. As I mentioned in my previous post two group 29s out performed my current 31s I have. Another thing to consider I guess is how the previous owner pulled cranks. I like to sit on the front deck and pull off the sides. I have no proof of it, but if I sat on the rear deck I bet my run time would decrease. Less bite on the trolling motor due to the bow being raised and more drag from the pad and big motor even being raised up, it would still be in the water some. I don't even trim my big motor up when pulling all the way now.
2nd suggestion, your set on buying two new 31s anyway. Buy a couple of good batteries install them and set the others to the side. Take the boat out on your local lake the first couple of times and see how it does. If the two new batteries don't do the job then you install the other two the way your describing. Always best to test your setup locally before you make a long trip to find out something isn't right.

Check these batteries out. The US 31DC XC2 Minutes of Discharge @ 25 Amps: 225, that's very good for a group 31.
The US 185HC XC2 Minutes of Discharge @ 25 Amps: 443, that is unbelievable and bet you could pull until the cows came home on two of those. Biggest thing is look at the dimensions they are larger and taller than 31s so want to make sure they could fit. In my battery compartment I would only have a couple of inches of clearance to the lid due to the height of the batteries. Also, I would have to get new battery trays.

Consider the size and length of the wire to the trolling motor. The smaller the wire and the longer the wire the more resistance and therefore more amps drawn. I have seen the suggestion that you should take battery leads off of the battery, turn the trolling motor switch on high and measure the resistance across the battery cables at the battery. Divide that number by the voltage and that gives you the amps drawn. Divide the amp hour rating on the battery and that should give you the number of hours you can expect at full speed.
