Well, since nobody else has chimed in, and you're waiting patiently for an answer, I will give you my experience with the issue. I didn't want to mount the transducer on my transom because of the drilling/mounting/sealing involved, so I bought a trolling motor bracket from BassPro and ran it that way. It worked fine. The only problems I had with that setup was the transducer wire would occasionally get in the way, and I could only use the fishfinder when the trolling motor was in the water. I then tried an aluminum transom bracket mount which mounted the transducer on the transom without the drilling/mounting/sealing steps. And with this setup, I can run the fishfinder while running the outboard. Personally, I like this setup much better. And if I ever change my mind or find something better, it's very easy to remove. I'm pretty sure the aluminum bracket was bought at Cabela's. No pictures of the setup, but if you're interested I can take one when i get home this evening.
