Trolling motor mount suggestions for Freedom 255

[tomob3]

I just purchased a 2015 Freedom 255. I'm interested in mounting a geo-locking trolling motor to the deck. The boat does not have a windlass so I think there's room. I'd like to do something that would be removable. Is anyone aware of a trolling motor with enough depth to reach from the deck to the water that is also powerful enough to hold a boat this size in position?

I have a 255 Freedom. I went with the 84” Rhodan, 36 volt. I have been out in 3’+ seas with heavy current and it holds the position and does not cavitate.
I bought the Grady trolling motor mount. It works well but was pricey.
