WATERLOO, IA (May 18, 2007) - John Deere Power Systems (JDPS) is pleased to announce the new 12.5L marine propulsion engine. The 6125SFM75 offers 610 horsepower (455 kW) and is the most powerful engine offered by John Deere.
This new engine model is EPA Tier 2 emissions certified, meets EU emissions requirements and is IMO compliant. The 12.5L engine is also M4 rated, indicating use for marine applications that operate up to 800 hours per year and have load factors less than 40 percent with one hour out of each 12 hours of operation at full power. At its M4 rating, the 12.5L offers 610 hp (455 kW) at 2100 rpm* and consumes 31.3 gallons of fuel per hour at full load rated speed.
"We are very pleased to be able to offer marine customers our highest horsepower engine yet," says Carl Micu, sales product manager. "Now that the newly configured 12.5L engine has an increased M4 rating, customers can get up to 610 horsepower out of one of our most popular engines."
The 6125SFM75 is based on the popular 6125AFM75 with design changes to accommodate sea water aftercooling and higher power. Some of those changes involve adding a sea water aftercooler, a viscous damper, a closed crankcase ventilation system, high-power electronic unit injectors, a larger heat exchanger, a new intake manifold, a new air filter, a high-flow sea water pump with rubber impeller, a larger water-cooled turbocharger and a new wiring harness.
"We're now able to offer our customers more options," Micu says. "The new 6125SFM75 marine engine is perfect for such applications as charter fishing boats, pilot boats, dive boats and planing hull commercial fishing boats, as well as trawler yachts and heavy-duty recreational applications."
The 12.5L engine is available at three other ratings*:
M3: 526 hp (392 kW) at 2000 rpm, 27 gallons of fuel per hour consumed at full load rated speed (M3 means 2,000 hours per year with load factors up to 50 percent for applications that use full power for no more than four hours out of each 12 hours of operation)
M2: 449 hp (335 kW) at 1900 rpm, 23.1 gallons of fuel per hour consumed at full load rated speed (M2 means 3,000 hours per year with load factors up to 65 percent for applications that are in continuous use and use full power for no more than 16 hours out of each 24 hours of operation)
M1: 380 hp (283 kW) at 1800 rpm, 19.5 gallons of fuel per hour consumed at full load rated speed (M1 means the application may operate up to 24 hours per day at uninterrupted full power for more than 3,000 hours per year and have load factors of more than 65 percent)
John Deere offers marine engines from 80 to 610 hp (60 kW to 455 kW) that meet EPA Tier 2 emissions requirements, as well as non-emissions certified marine engines that range in power from 75 to 610 hp (56 to 455 kW). Please visit www.JohnDeere.com/marine for more information.
