John Deere announces new JD14 and JD18 marine engines

22 January 2025

Deere & Company announced new JD14 and JD18 marine engines, which can offer marine customers heavier duty cycles and an expanded power range from 298 to 599 kW (400 to 803 hp). Production is anticipated to begin in 2026.

The JD14 marine engine—intended for passenger vessels, pilot boats, and various workboat and pleasurecraft applications—is a 13.6 L, 6-cylinder engine with an anticipated power range of 298-599 kW (400-803 hp). The JD14 marine engine will feature a reduced package size compared to the John Deere 13.5 L 6135SFM85.

The JD18 marine engine is intended for commercial fishing, passenger vessels, and tugboat applications. The engine has an 18.0 L displacement and anticipated power levels of 410-599 kW (550-803 hp). It will provide up to 522 kW (up to 700 hp) of uninterrupted power at the M1 rating and up to 599 kW (up to 803 hp) of power at the M2 rating. In addition to the M propulsion ratings, both the JD14 and JD18 engines will be available with variable-speed auxiliary and constant-speed auxiliary and generator ratings.

The JD14 and JD18 marine engines are built upon the John Deere clean-sheet Next Generation Engine architecture announced in 2022. The new marine engines feature:

• A high-pressure common-rail (HPCR) fuel system to optimize fluid consumption and help boost fuel economy for commercial operations facing tightening margins.
• A rear gear train that provides customers with up to two rear PTOs and capacity for auxiliary power.
• An overhead camshaft design and hydraulic lash adjusters to achieve better valve fit and eliminate valve lash maintenance.
• Higher duty cycle and up to a 500-hour extended fluid service interval.

The JD14 and JD18 marine engines will be IMO Tier 2, US EPA Tier 3 and EU RCD II certified. They will also be compatible with renewable diesel fuel and biodiesel blends.
