John Deere Power Systems is pleased to announce a redesigned PowerTech 6068SFM75 marine diesel engine that offers a power range of 249 up to 400 hp. The redesigned PowerTech 6068SFM75 joins the PowerTech 6090SFM75 550hp and 6135SFM75 at 750 hp to complete the John Deere high horsepower marine engine lineup. The new 6.8L marine engine represents John Deere's continued commitment to offer customers a complete lineup of marine engines rated for commercial fishing and high-speed recreational craft. John Deere's redesigned 6.8L marine engine is 229 mm narrower than the previous 6068SFM75 design, which offers a more compact engine for vessels with reduced clearances in the engine room. The 6.8L propulsion engine is due to hit the water in the fall of 2011, while the generator drive ratings will be available in 2012. The newly redesigned engine meets Environmental Protection Agency Marine Tier 2 European Union emissions requirements and is MARPOL Annex VI compliant. The PowerTech 6068SFM75 M1 series has 6.8L of displacement and offers 249hp at 2400rpm, in a 6-cylinder, electronically controlled, turbocharged and air-to-seawater after cooled marine engine.
