Wayne. Difficult one this, everyone will have their own preferances.
To start with, what battery do you think you will be using ?? I would have thought a large gel cell, say a 12v 7A hr one or something would do..you will need a bit of ballast anyway. An MFA 800 turning a 50mm Prop on a 5mm shaft would be an option, or a geared 850 for more oomph…or come to that just an 850.
There are several 900 types out there to direct drive a large prop..or geared 700`s.
I am afraid a surf will be needed, perhaps Cornwall model boats…they have a good range of motors and geared units.
The hull looks a bit yacht like? from the bottom view.
Personally wouldnt bother with a waterproof shaft. Wont have much leakage and in a fibreglass hull of that size it wont matter anyway.
