That minnkota 28 is actually a 28amp motor but will reach a max of 35amps.
Deep cycle batteries are always recommended for any type of freshwater applications. Since you can only charge it at home or through the use of a plug in charger, the battery will only discharge with use.
Normal lead acid batteries are not designed for the continuous draining down and recharging.
To figure your battery size simply take the max amperage of your motor, and calculate the max amount of time that you will need to use the motor. Figure on a 10 hour day so that you don't come up short.
Your minimum size battery should be a 350ah battery. Or simply multiply that by 5 Cold Cranking Amps and you will come up with a Deep Cycle 1750CCA battery.
You can always go with a bigger battery if you desire. This recommendation is only for a minimum size requirement.
