Mounting trolling motor on pontoon

Putting a 24v system on my pontoon. The pontoon is set up for a 12v system currently. Will rewire the boat running the wire from the back of the boat where the batteries are to the front. I will stay completely away from the preexisting 12v system as I will use it for my depth finder. Looking for some type of "solution" at the front (some type of box or outlet where I can connect my trolling motor plug to the wires). Have thought about using an electrical box and plugging in the trolling motor plug. Anybody ever done this??? What did you use for your junction box to plug in your trolling motor plug? Just trying to make it where it doesn't look cobbled together..thanks

I would use a Gray plastic weatherproof box.
