Okay....got my PS31, GT52 (trolling motor), and GT 15. Just trying to wrap my head around anything on the transom. I'd prefer not to drill on the transom, although I have a transom-saver block that I can adhere to it if needed. My goal would be to install on the holeshot plate under my 6" Atlas jackplate.

With the GT15, am I better off putting it in the bilge or can I put in the drain area right in front of the bench seat? Also, I haven't bought the second GT52 yet, because I understand the GT30 is the only one that works with a Y-cable to the GT15 for on plane depth readings? What do I gain/lose with the GT30 vs. GT52 on the transom? I'm using 76xx series Garmin units, two on the bow and one on the console.

Thanks!
