Propspeed is the original and best foul-release coating system for propellers, running gear, and underwater metals. Unlike traditional antifouling, Propspeed is a non-toxic coating that uses a slick silicone surface to prevent marine growth from attaching. This results in more speed, better fuel economy, and protection against corrosion. The Propspeed range has expanded to include Foulfree for transducers and Lightspeed for underwater lights.
