Custom Trolling motor mount

[ANAYALATOR]

Hello I just bought a 2002 maxum 1800 SR runabout. I would love to be able to mount a trolling motor to the bow. Is there some kind of custom mount that would fit level so I can mount a trolling motor to it? Also how do I know what size of trolling motor(length) I would need? If anyone has suggestions I would appreciate it, thank you in advance✌️ , Nino
