The HD3 is a commercial duty 200 horsepower steerable Z-drive designed for use in all types of vessels. These tough Z-drives have short legs along with heavy duty fixed pitch propellers for shallow water operation. Combined with a extra large steering gear, rugged housing and protective shear pins, these robust steerable Z-drives thrive in some of the worst marine environments.
This rugged azimuth has the option of being fitted with a nozzle for applications trying to maximize thrust. The HD3 has been installed on boom boats, small tugs, yachts, small passenger vessels, self propelled barges, Canadian Coast Guard buoy tenders, oil skimmers and more.
