At both low and high speeds, the three- and four-blade propellers seem to meet the same fuel efficiency standards. However, at mid-range RPMs, four-blade propellers almost always provide higher fuel economy. With its 13-inch diameter and 17-inch pitch, the PolaStorm 4389-4130-17 propels your boat forward 17 inches in a single round. It is stainless steel, which is more durable and corrosion-resistant than aluminum. Each propeller for a Pola storm boat is made of premium materials for greater strength and has a thinner blade that is smooth, quick, efficient, and long-lasting. The primary goals of Pola Storm are to increase production yield, first-in-first-out practices, and automated machinery (such as robotic dipping arms).
