I mounted the ducer to the right. It's unaffected by the propeller. The information is the same if the engine is running or stopped. It has not been a problem with our trailer.

The ducer was no problem even though it is longer than the usual old style. I went to a lot of trouble to install mine by first carefully sealing the old ducer screw holes. In then cut a piece of 3/4" white Starboard marine lumber and fitted it to the transom to serve as a mounting surface for the new ducer. I used Gorilla Tape to dry mount the Starboard before drilling and mounting it to the transom. I did the same with the ducer being particularly careful to get the height perfectly set. I then screw mounted the ducer to the Starboard.

The transom on our 13 is curved therefore the ducer points a little to the right but that has not affected performance. Mounting the very rigid Starboard was not a lot of fun. If you use it, cutting a few vertical "kerfs" about half way through the Starboard toward the center could make it more bendable.
