I am planning on purchasing a new trolling motor with GPS to anchor down. The only difference between the XI3 & XI5 I can find is.. One comes with a pedal and the other does not.

Anyone know if the build or operation is different? I have an RT178 and have been told shaft lengths of 45"-54".. So that is another answer I would like to ask about. What length is best for DFW area waters. I have read people complain about the wireless pedal, but wanted to ask those that have first hand experience with these TM what they think.
