If you do the math on the reduced speed and fuel burn over time, there is not a lot of benefit. The engine would be grossly undersized as a single and the load increased exponentially. Not worth costing thousands on engine life to save 10's on fuel.

Consider load like trying to pedal a bike in the highest gear. It's not about speed, it's about resistance. A feathering prop would be insignificant compared the small single engine and the mass of the boat.
