Deere & Company has introduced two new John Deere marine engines, the JD14 and JD18, expanding their power range for marine customers. These engines will offer heavier duty cycles and a broader power range, from 298 to 599 kW (400 to 803 hp), with production set to begin in 2026. Pierre Guyot, senior vice president of John Deere Power Systems, emphasized the engines’ high performance, fuel efficiency, and rugged durability, catering to the demanding needs of commercial marine operations.
The JD14 marine engine, suitable for passenger vessels, pilot boats, and various workboats, is a 13.6-liter, 6-cylinder engine with a power range of 298 to 599 kW (400 to 803 hp). On the other hand, the JD18 marine engine targets customers in commercial fishing, passenger vessel, and tugboat markets, boasting an 18.0-liter displacement and power levels from 410 to 599 kW (550 to 803 hp). Both engines offer various propulsion ratings, including variable-speed auxiliary and constant-speed auxiliary and generator ratings.
To bring the JD14 and JD18 marine engines to market, John Deere utilized its clean-sheet industrial Next Generation Engine architecture, focusing on customer value throughout the design process. Key features include a high-pressure common-rail fuel system for improved fuel economy, a rear gear train for rear PTOs and auxiliary power, an overhead camshaft design for better valve fit, and a longer 500-hour extended fluid service interval. These engines are certified to meet IMO Tier 2, EPA Tier 3, and EU RCD II standards, as well as compatible with renewable diesel fuel and biodiesel blends.
