Props are measured by inches. A 54-50 means in perfect fluid conditions that prop will go 50 inches in 1 revolution. Some prop manufactures use degrees so that you can set the prop on site. If you talk to Edd he will explain it. The reason different props perfume differently in the air is there design. This includes boat prop.
