Stainless propellers are thinner than aluminum but stronger at the same time. You will definitely gain a bit of speed and economy by going to them. They can be repaired more often than aluminum. You can normally go up one hole higher on the transom if so desired but not always the case. Dont drive yourself nuts getting into diameter vs pitch. Go with the same pitch if staying with a 3-blade or go down 1" in pitch if going to a 4-blade. In almost every case you can go up a hole in height with a 4-blade and your out of the hole acceleration will improve as will your cruise speed and economy. In a nut shell thats about all you need to know. Stay with a quality prop manufacturer. Happy Memorial Day!
