Some quick numbers on the force of the water against the blade surface area and mass of the propeller shaft (worst case not spinning) including the distance to travel to the rudder the impact against the rudder ends up being incidental. Plus the blade contacting the rudder would be at the tip of the blade which would yield and roll over close to the rudder bearing (lowering the bending moment) further cushioning any impact . Unless the rudder was significantly cracked and ready to fall off I can't see this situation panning out.
Tom, while we are waiting for an update from Lawrence......I had a question for you. How does Algonac attach a stainless shaft to a bronze rudder plate?
