i can get a 3 blade aluminum for $60 or a 3 blade steel for $120
what are the pros and cons of either prop and which would you go with?

Pros of AL: cheap, possibly some degree of l/u protection from prop strikes (debatable)

Quackrstackr said:All things being equal, a 2 blade should be faster and more efficient than a 3 blade because of reduced drag and friction, less rotating mass, etc.
It just depends on what you want. More blades equals more low end performance and less blades equals better top end.
Notice on most trolling motor props that their 2 blade versions are usually marketed as "power props" while their 3 or even 4 blades are general purpose or weed whacker props.

I woudl not waste the money on a SS prop for a motor of that size. Instead, get a few different aluminum or even composite props with different pitch and blades and see which gets you what you want with your motor, hull and weight
