Ro Ro Co. owner Tom Hanna chose these engines to repower his cargo carriers because Mitsubishi engines are simple, reliable and mechanical, Laborde says. The Mitsubishis also provide him with much better fuel consumption than the older engines that he had been operating, the North American Mitsubishi distributor says, and Mitsubishi offers an assortment of horsepower ranges in a 6-cylinder engine.
Mitsubishi’s heavy-duty marine propulsion engines are fully mechanical and EPA Tier 3 compliant without the use of complex electronics or any after-treatment, and typically offer larger displacement and more mass than other engines, says Covington, La.-based Laborde, which services a far-reaching territory from Texas to Florida and New Orleans to Minneapolis.”
