This is principally owing to the extreme variation in costs in the geographical areas The larger the diameter of the propeller, the slower the shaft speed RPM that is However the trade-off is that, with fewer blades, each one carries more load. As the propeller blades turn in the water, they generate high-pressure areas 

Marine propulsion – Wikipedia

Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or engine turning a propeller, or less frequently This, along with improvements in boiler technology, permitted higher steam
