VETUS f/BOW125/130/160 Propeller. Set includes all mounting hardware for propeller. Working in close collaboration with the Maritime Institute Netherlands (MARIN) the world-famous hydrodynamic laboratory VETUS has optimized the performance of its thrusters. This has been achieved by utilizing a unique propeller blade profile which creates little or no cavitation. As cavitation produces unwanted noise this new blade design offers a major reduction in the operating sound levels for VETUS bow thrusters. Moreover the application of this propeller has reduced the current consumption by up to 10percent.Zinc sold separately.
