I think you will want one that has a seperate transducer wire so it can go with the trolling motor up front. Or put your own quick disconnect in the transducer cable. You will have your transducer cable tied to the trolling motor shaft.

In the back I would get one of those clamp on transducer holders so you can move the transducer from boat to boat. A portable fishfinder may work easier here for moving boat to boat.

My neighbor has a quick release trolling motor mount and I watched him use it once seem to work okay.

Someday you may want to consider a stick steer boat so you don't have to move from back to front. Or get good with a rear mount trolling motor so you can just stay in the back. I have tried an older remote control trolling motor..its not for me. Maybe the new ones okay but expensive. Good thing about the old transom mount they are cheap.

I rigged a seat up front on a pedestal pole so I don't have to sit on the bench and I can turn all the way around. I have a couple length poles so I can sit deeper in the boat when I want...and one casting butt seat when I want to sort of use it like a bass boat but my feet are still on the floor....no deck. It's a modified Lowe Big John 16/48 and has a middle bench.
