John Deere marine engines meet the requirements of the European Recreational Crafts Directive (RCD – 2003/44/CE) emissions standard and therefore, can be used as propulsion engines for recreational boats on the Constance Lake, according to the Bodensee Schifffahrts Ordnung (BSO). They also comply with the EPA Recreational Tier 2 emissions standard.

Specifications and design subject to change without notice.
John Deere 4- and 6-cylinder inline 75-525 hp (56-392 kW) diesel engines are available for propulsion, auxiliary and gen-set installations. "M" power rating guidelines assure your engine provides reliable and long lasting performance.
M1: The M1 rating is for marine propulsion applications that may operate up to 24 hours per day at uninterrupted full power. These applications typically operate over 3000 hours per year and have load factors* over 65%. The M1 rating is the ISO 8665 "standard power" rating and the SAE J1228 "crankshaft power" rating. ISO standard power and SAE crankshaft power are defined as the power level an engine can run at continuously between recommended service intervals.
Possible Applications: Line haul tug and towboats, fish and shrimp trawlers/draggers, and displacement hull fishing boats over 60 ft (18 m).
M2: The M2 rating is for marine propulsion applications that operate up to 3000 hours per year and have load factors up to 65%. This rating is for applications that are in continuous use, and use full power for no more than 16 hours out of each 24 hours of operation. The remaining time of operation must be at cruising speeds.
Possible Applications: Short range tugs and tow boats (pool boats), long-range ferryboats, large passenger vessels, and offshore displacement hull fishing boats under 60 ft (18 m) long.
Marine auxiliary power engines for dedicated hydraulic pump drives, dredge pumps, or other constant load marine applications should use the M2 rating.
M3: The M3 rating is for marine propulsion applications that operate up to 2000 hours per year and have load factors up to 50%. 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 must be at cruising speeds.
Possible Applications: Coastal fishing boats, offshore crew boats, research boats, short-range ferryboats, and dinner cruise boats.
M4: The M4 rating is for marine propulsion applications that operate up to 800 hours per year and have load factors below 40%. This rating is for applications that use full power for no more than one hour out of each 12 hours of operation. The remaining time of operation must be at cruising speeds.
Possible Applications: Inshore crew boats, charter fishing boats, pilot boats, dive boats, and planing hull commercial fishing boats.
M5: The M5 rating is for marine recreational propulsion applications that operate 300 hours and less per year and have load factors below 35%. This rating is for applications that use full power for no more than 30 minutes out of each 8 hours of operation and do not operate for the remaining 16 hours of the day.
Possible Applications: Recreational boats in the U. S., tactical military vessels and rescue boats outside the U. S.
*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 8-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%.
