JDPS Releases New Propulsion Engine

Monday, September 10, 2007
John Deere Power Systems (JDPS) is announced the new PowerTech 6.8L marine propulsion engine. The 6068SFM75 offers up to 298 kW (400 hp) and is the newest marine engine offered by John Deere.

This new engine model meets EPA Tier 2 and EU emissions requirements and is MARPOL Annex VI compliant. The 6.8L marine engine is available in M1 through M5 ratings. The M5 rating is for marine applications that operate 300 hours or less per year and have load factors less than 35 percent with 30 minutes out of each 8 hours of operation at full power. At M5, its highest rating, the 6.8L offers 298 kW (400 hp) at 2800 rpm* and consumes 77.6 liters of fuel per hour (20.5 gallons) at full load rated speed.

The M5 rating is most suitable for recreational applications, but the engine’s four other ratings, which are suited for both recreational and commercial applications, also offer increased horsepower. The 6068SFM75 offers top-of-class fuel economy for every rating at both full load rated speed and typical cruising speeds. The 6068SFM75 is a new marine engine design based on the heavy-duty John Deere off-highway PowerTech 6.8L engine used in John Deere agricultural and construction and forestry machines. This engine offers new features such as a 4-valve cylinder head, a high-pressure common-rail fuel system with pilot injection, a new seawater aftercooler, a heat exchanger with integrated top tank, a water-cooled exhaust manifold and turbo, as well as a viscous damper and a closed crankcase ventilation system.
