www.marinelink.com Laborde Repowers Harbor Tug Fleet Osage Marine Service, Inc., a fleeting service with locations throughout the Midwest, turned to Laborde Products to provide products when harbor tug Deborah Ann was in need of an engine overhaul. Laborde supplied Osage's St. Louis, Mo., branch with twin Mitsubishi S6A3-Y2MPTK engines rated 483 hp at 1,840 rpm to repower the vessel that is mainly used for switching docks and working line boats. Osage Marine already has a set of 940 hp engines from Laborde for the next repower and four more on order for next year. It plans to upgrade the entire fleet with EPA-compliant propulsion engines.
