I am not sure if mounting the FF in the stern will effect the performance in a significant way but if you have a Revo, there may be a good reason to mount there. The space in rear hatch on the Revo is not easily accessible while on the water and therefore the real estate is less valuable, at least to me. Having the transducer mounted there would save some storage space up front.
I store my FF battery in the otherwise mostly useless tray that came with my Revo. The stern is usually dryer than the bow and therefore probably a good place for electrical stuff to live.
Give it a try.
