I have a new terrova and it’s a 12 volt , so I’m no help on that part. What I can talk of is the PD V2 24 volt 70 lb with auto pilot and co pilot. I’ve had it near ten years and I use my equipment but also take care of it and it’s usually stored out of the weather. I’ve had zero issues with the motor or anything to do with it. When I troll I’m usually on the motor constant for no less than 4 and as many as 7 hours without a hiccup. The performance and durability of this motor led me to buy the 12 volt Terrova for my current boat. Only two things kept me from using the PD V2 on my current boat. One was the second battery that I had no room for and the spot lock feature. Anyone that fishes in any wind at all appreciates that feature. The PD is still running fine and for sale to a new home so I can’t yet say how long they last but it’s longer than I’ve owned mine.
