What's wrong with this! It's a 2 blade prop

 

[Slow Mo^cean]

3 blade props are overrated anyways...

Throwing a blade into the hull could do some damage, I would think.

I've read that single-bladed propellers are the most efficient for displacing air or water ... efficiency declines as blades are added. The problem is vibration. Vibration is the worst with a single blade and improves as blades are added. Everything is a compromise! <sigh>
