EVALUATION OF MURRAY AND TREGURTHA MODEL 9D-200 PROPULSION UNIT,

Abstract

Tests were made to determine the relative merits of the outboard propulsion units, Models 9D-200 and 06DH, for shallow-water operations. The 9D-200 was designed to replace the heavier and more expensive 06DH for use on warping tugs in amphibious operations. Its principal features are automatic hydraulic tail-section elevation and a smaller propeller, which enable it to work more efficiently than the 06DH in shallow water. Tests indicated that the 9D-200 is more reliable and resistant to damage in shallow whater than the 06DH but that in deep water the 06DH develops more thrust. (Author)
