Marine Applications: Diesel Engines

Nothing Runs Like A Deere™

John Deere PowerTech™ engines are as powerful and dependable in the water as they are on the land. Our marine propulsion, generator, and auxiliary engines share the same reputation for performance and reliability that their agricultural and industrial counterparts have enjoyed for decades. They are built for long life, reliable performance, fuel efficiency, quiet operation, ease of access to major parts, and simplified integration. But don’t just take our word for it. Find out why John Deere is the powerful and reliable choice.

Meeting regulations around the world

John Deere marine engines comply with international, European, and United States emissions standards for regulated vessels. John Deere meets U.S. Environmental Protection Agency (EPA) Marine Tier 3 emissions regulations with a complete line of PowerTech engines for newly constructed vessels as well as repowered boats.

• EPA Tier 3 regulations for vessels flagged in the United States
• European Union Nonroad Mobile Machinery (NRMM – 97/68/EC as amended), whose standards are also recognized by the CCNR for sailing on the Rhine
• European Union Recreational Craft Directive II (RCD II)
• International Maritime Organization (IMO) Tier II
• Engine International Air Pollution Prevention (EIAPP) certificates issued by the EPA or American Bureau of Shipping (ABS) are available for select engine models.

Engines for non-regulated territories

In addition to the engines for various emissions regulations mentioned, John Deere offers engines for the non-regulated regions throughout the world.

Marine classification societies

John Deere provides a full line of marine engines designed to meet the requirements of the various marine classification societies.

Marine propulsion M ratings

Ratings are based on the ISO 8665/SAE J1225 standard power rating and the ISO 3046/SAE J1995 crankshaft power rating. The M rating definitions are provided as a guide to help in the selection of the engine that best fits the application requirements. It is recommended to consult a John Deere marine dealer or engine distributor to verify the optimal rating for the specific application.

¹ Load factor is the actual fuel burned over a period of time divided by the full-power fuel consumption for the same period of time. For example, if an engine burns 160 liters of fuel during an eight-hour run, and the full-power fuel consumption is 60 liters per hour, the load factor is 160 liters / (60 liters per hour x 8 hours) = 33.3 percent.

† Cruising is any operating time where the engine speed is more than 200 rpm less than the maximum attainable engine speed.

Propelled performance

John Deere engines give you an effective blend of pure power and strong-willed durability. From 60 to 559 kW (80 to 750 hp), our complete, high-horsepower lineup offers the right engines for your needs — each of them with added torque at slower speeds. The result? John Deere engines build power faster for cruising at higher speeds with lower rpm. Boost your vessel’s performance in wind, swells, tides, or currents with reliable power that’s ready when you are.

Power that never lets you down

John Deere is a trusted provider of generator drive engines worldwide. For reliable power from  40 to 416 kW (54 to 558 hp), John Deere generator drive and constant-speed auxiliary engines deliver quiet operation and low vibration. The water-cooled exhaust manifolds provide cool, quiet performance. And all 4-cylinder models have internal balance shafts to reduce vibration. 

Marine generator drive engine ratings

The marine generator engine rating is the power available under normal varying electrical load factors³ for an unlimited number of hours per year in commercial applications. This rating incorporates a 10 percent overload capability, and conforms to ISO 8528 prime power. Average load over a 24-hour period shall not exceed 67 percent of the prime rating, of which no more than two hours are between 100 percent and 110 percent of the prime rating.

This rating is used for applications that require constant speed in auxiliary applications.

³ Load factor is the actual fuel burned over a period of time divided by the full-power fuel consumption for the same period of time. For example, if an engine burns 160 liters of fuel during an eight-hour run, and the full-power fuel consumption is 60 liters per hour, the load factor is 160 liters / (60 liters per hour x 8 hours) = 33.3 percent.

⁴ EX = MARPOL Annex VI exempt. Also meets EU Stage III A emissions regulations. Specifications are subject to change.

Dry-exhaust or wet-exhaust manifolds

John Deere PowerTech radiator-cooled, dry-exhaust manifold engines (TF and HF models) are engineered to run vessel auxiliaries such as pumps, winches, deck cranes, and hydraulics. With displacements from 4.5 to 13.5 liters and power ratings from 74 to 448 kW (99 to 600 hp), meeting EPA Marine Tier 3 requirements has never been easier. John Deere PowerTech radiator-cooled, wet-exhaust manifold marine engines (HFM models) are rated to provide dependable auxiliary power for oceangoing vessels and other applications that require type approval for marine classification societies. With power ratings from 242 to 373 kW (325 to 500 hp), these engines are ready to work.
