John Deere Power Systems
(JDPS) is introducing a redesigned PowerTech™ 6068SFM75 marine diesel engine
that offers a power range of 249 hp to 400 hp in a more compact 6.8-liter
The redesigned PowerTech 6068SFM75 joins the 550-hp
PowerTech 6090SFM75 and the 750-hp 6135SFM75 to complete the Waterloo,
Iowa-based engine manufacturer’s high horsepower marine engine lineup. The company
says the new 6.8-liter 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 6.8-liter marine
engine is 9 inches narrower than the previous 6068SFM75 design, which offers a
more compact engine for vessels with reduced clearances in the engine room. The
6.8-liter 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.

smaller size gives us an engine in the 7.0-liter size range that will
complement our 9.0-liter and 13.5-liter marine engines,” Flaherty added.
The company says the engine is an ideal choice
for a variety of applications that include commercial fishing vessels, small
workboats, sportfishing boats and high speed yachts.
