My prop is a 3 blade Flexofold, described by the manufacturer as: Cast Nickel/Aluminum/Bronze (NIBRAL), high strength, corrosion resistant and 82% copper for anti-fouling. I am not sure the anti-fouling features is working because the prop has to be cleaned every 3 to 6 months to get rid of the barnacles otherwise the motoring speed drops by 1 knot. The boat is in the Med, sailed most days from April to November. Is this to be expected? Any solutions, including anti-fouling and vaseline?
