Most Powerful John Deere Launched

The 12.5 litre 6125SFM75 offers 610 horsepower (455 kW) and is EPA Tier 2 emissions certified, meets EU emissions requirements and is IMO compliant.

The new 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% with one hour out of each 12 hours of operation at full power. At its M4 rating, the 12.5L offers 610hp (455 kW) at 2,100rpm and consumes 31.3 gallons of fuel per hour at full load rated speed.

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.

The new 6125SFM75 marine engine is suitable for applications such 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: 526hp (392kW) at 2,000rpm, 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% for applications that use full power for no more than four hours out of each 12 hours of operation)
• M2: 449hp (335kW) at 1,900rpm, 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% 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: 380hp (283kW) at 1,800rpm, 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%)

John Deere offers marine engines from 80 to 610hp (60 to 455kW) that meet EPA Tier 2 emissions requirements, as well as non-emissions certified marine engines that range in power from 75 to 610hp (56 to 455kW).
