I mounted the transom mount transducer for a hb 798ci hdsi on my terrova and I am having some problems with the picture. I am not sure if it is because of the turning or the ducer itself. Do others have the transom mount on the trolling motor and is the pic good? It sticks out away from the TM a little while the TM transducers do not. I am thinking I might have to spend the money to get the TM ducer to get the pics I want but wanted other opinions before I spent the money and went back through the install process. Thanks
