Development, Test and Evaluation of Hydraulically-Driven Marine Outboard Propulsion Units

Abstract

Naval Amphibious Construction Battalions have used propeller-type out board propulsion units since World War II to move Navy Lighter (NL) pontoon craft such as lighters, barges, and floating cranes in harbors, and for warping tugs in amphibious operations. This type of unit, as illustrated in references 1 and 2, consists of a deck-mounted frame with an engine, plus a tail section extending downward over the stern of the craft about six feet below the deck. A power train, from the engine to a propeller at the lower end of the tail section, passes through two right-angle drives which require expensive, high precision gears. A misalignment of the gears, causing damage requiring extensive repairs, may result from either the propeller or tail section striking a submerged object or the sea bottom.
