What do you have for an engine in your boat?
I personally wouldn't o nuts. A properly spec'ed Stainless Steel prop will set you back a few hundred and might eek out a couple more miles per our but that first rock you hit, the blades might not give way, and you could damage your lower end. An aluminum prop will likely sheer a blade before damaging the lower end.
Clammer's different. He uses Magnetic props and fishes around a lot of iron ore
