Thought I'd ask the collective wisdom of the'Fire.

I just bought a new boat--lucky me--its a 17ft Crestliner with a 115hp Merc 4 cycle. Big diesel Tugs and small skiffs with 20hp motors I understand, but runabouts like this a new to me.

I got a couple of questions, why are stainless steel props 3 times as much money?

The boat came with a A45 17p prop--I can get a SS but its 19p for cheap--what will change performance wise?
