I bought a used Minn Kota Power Drive V2 Pontoon 68 lb thrust trolling motor with co-pilot from a guy the other day who assured me it was top of the line. I asked him if it had a built in transducer and he didn't know. He also didn't know what infinite speed was on it either, I think he was a boater and not a fisherman. He is trying to find the manuals as he bought it new a couple of years ago at Bass Pro, I don't hold out much hope for him finding this as he is moving from one house to another. My question...what do I look for on the motor for a built in transducer? Thanks in advance.
