The Terrova w/I-pilot will come with both the remote and foot pedal. A Powerdrive w/I-pilot can only be used with the remote . Personally, I like to use the foot pedal when jigging the river so my hands are free, but use the remote when trolling. It's nice to have the foot pedal as back up in case there would ever be an issue with the remote.
As far as mounting to your boat, It's hard to tell from the pic, but I'm thinking you are going to need to add some type of plate or bar across the bow behind the factory plate to give you a little more surface area to bolt it down. Not sure how much area that current bow plate gives you to work with.
