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 Titan propeller is a performance propeller for high speed planing hulls. It's high-rake design provides excellent bow lift, acceleration, and top speed. Titan's cupped-blade design increases bite and reduces slip. 13.25" Diameter. 17" Pitch. Right Hand Rotation.
