NOTES:

In 1837, John Deere, blacksmith and inventor, had little more than a blacksmith shop, a discarded steel saw, and an idea that would help farmers, changing the face of agriculture for all time. Today, Deere & Company is one of the world’s most admired businesses.
See our John Deere webpage for company history and contact information, PLUS information about other John Deere Products.

 John Deere Marine (M) Engine Duty Ratings

The M rating definitions are provided as a guide to help in the selection of the engine that best fits the application requirements.
Ratings are based on the ISO 8655 standard power rating and the SAEJ1228 crankshaft power rating.
The M1 rating is for marine propulsion applications that may operate up to 24 hours per day at uninterrupted full power and have load factors* greater than 65 percent.
Possible applications: Line hauls tugs and towboats, fish and shrimp trawlers/draggers, and displacement hull fishing boats.

The M2 rating is for marine propulsion applications that typically operate between 3,000-5,000 hours per year and have load factors* up to 65 percent. This rating is for applications that are in continuous use and use full power for no more than 16 hours of each 24 hours of operation. The remaining time of operation is at or below cruising† speed.
Possible applications: Short-range tugs and towboats, long-range ferryboats, large passenger vessels, and offshore displacement hull fishing boats.

The M3 rating is for marine propulsion applications that typically operate between 2,000-4,000 hours per year and have load factors* up to 50 percent. This rating is for applications that use full power for no more than four hours out of each 12 hours of operation. The remaining time of operation is at or below cruising† speed.
Possible applications: Coastal fishing boats, offshore crew boats, research boats, short range ferryboats, and dinner cruise boats.

The M4 rating is for marine propulsion applications that typically operate between 1,000-3,000 hours per year and have load factors* below 40 percent. This rating is for applications that use full power no more than one hour out of each 12 hours of operation. The remaining time of operation is at or below cruising† speed.
Possible applications: Inshore crew boats, charter fishing boats, pilot boats, dive boats, and planning hull commercial fishing boats.

The M5 rating is for marine recreational and certification for light duty commercial Tier 3 propulsion applications that operate between 300-1,000 hours per year and have load factors* below 35 percent. This rating is for applications that use full power for no more than 30 minutes out of each eight hours. The remaining time of operation is at or below cruising† speed.
Possible applications: Recreational boats, tactical military vessels, and rescue boats.

* 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.
