The cable on the Kraken reached "just " thru the bulkhead to the cabin. (48" i think)
I mounted a weatherproof box in the cabin on that fwd bulkhead.
I ran the 6awg from Refrig space, thru water heater space, into anchor locker, and up to and thru the back of the box.
I mounted a 60A MRCB breaker switch. The Positive power is swicthed. The negatives are on a separate terminal post in the box.
I'll have to post more detail of that. I think I used 5/16 lugs and terminals.

So all connections are in the cabin.
You will need a trolling motor plug and socket because you are going to use a quick disconnect mount.
I would assume you put the socket in the anchor locker(safely) and a plug on the 48" cord. Go in thru the hatch to plug in..
You could put the socket on deck but ...salt water.....
