They do still make the "power drive" in a V2.. I figured they had discontinued it. It's kind of silly... Both motors are almost the same with most of the same features. You can get the powerdrive with the "updated" AP or you can get the Terrova without the "updated" AP. So the main differences seems to be the foot pedal and the options on the remotes, which aren't interchangeable.. They both have their own version of an updated stow and deploy assist... After that, it's what thrust and what shaft do you want. One main difference seems to be that an AP upgrade on the Terrova is kind of cost effective where it isn't on the Powerdrive V2.
