This might answer your question. I am pretty sure your going to have issues getting the pod and wet switches covered by at least a inch of water for it to work. The shaft length of the ultrex mega 360 is 39” and the pod is another 9”. Your better off to maybe get a separate attachment device like a DaDucer from podunkideas.com and install the mega 360 on it. Or buy the Mega 360 Universal which has a 50” shaft length. HB website shows out of stock but give bbc marine electronics, a crappie.com sponsor as he might have one in stock if you choose to go that route. I have my mega 360 in a DaDucer and really like the setup.
