This rating is for applications that use full power for no more than 30 minutes out of every eight hours. The remaining time of operation is at or below cruising speed3


Possible applications: recreational boats, tactical military vessels, and rescue boats.

1John Deere will provide a 5-year/5,000-hour (whichever comes first) factory extended warranty free of charge to customers who purchase a new, qualifying M5-rated marine engine from authorized U.S. and Canadian John Deere marine engine distributors and dealers between September 1, 2020, and February 28, 2021. For extended warranty terms and conditions, contact your distributor or dealer for details. Engine warranty registration and an application for extended warranty must be completed within thirty (30) days of purchase. A sea trial must also be passed by August 31, 2021, unless John Deere approves an extension, in writing. This promotion is not available for direct purchase of M5-rated marine engines from John Deere. Engines for marine generator drive, constant and variable-speed auxiliary, and any other non-M5-rated propulsion applications do not qualify.

2Load 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.

3Cruising is any operating time where the engine speed is at least 200 rpm less than the maximum attainable engine speed.
