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 Saturn 3 propeller is designed for all-around general purpose performance with good acceleration and is a more durable and cost effective replacement for aluminum props. 13" Diameter. 19" Pitch.
