I use my MarCum on the bow of my boat every year. One on the bow one on the dash. You need to buy the trolling motor mount transducer for the bow or the high speed for the stern. The mount real easy.
On my boat I run my graph through the Minn kota universal ducer and have the MarCum ducer mounted next to it. I strongly recommend using a flasher on your boat, that real time feedback is great.
