This unique design offers an “overdrive feature”, with 2 controlled pitch settings in forward and full reverse thrust. The “overdrive feature” gives lower engine RPM for the same cruising speed when in calm waters or motor-sailing. The 3-blade propeller is available in diameters from 15” ~ 30+”, and pitch settings between 60% and 80% of the diameter. They are available in both LH and RH configurations for both saildrive and shaft installations.
