The Hung Shen KCA-4B is a traditional propeller for fairly efficient operating speeds below 25 knots. The vibration and noise produced by this propeller for medium and high shaft inclinations is minimal. Hung Shen KCA-4B & 5B propellers are for use on vessels operating at speeds lower than 30 knots. The blades are wider to help control cavitation on the blade surface. The level of vibration produced by these propellers is lower than the KCA-3B propeller.
