Each Solas boat propeller is balanced and precision made with superior materials for a higher strength and thinner blade that is smooth, fast, efficient and tough. Each stainless steel propeller is made with the industry's highest percentage of chromium, nickel and molybdenum, resulting in a boat propeller that is more rigid, highly rust resistant and less brittle. The HR Titan propeller offers powerful thrust and very smooth performance with increased speed and economy in the mid-range. Its high-rake and cupped-blade design provides great stern lift and acceleration. 13-7/8" Diameter. 19" Pitch. Right Hand Rotation.
