John Deere unveils New Engines, Expanded HP for Workboats

Deere & Company announced the unveiling of new engines — the JD14 and JD18 marine engines.

With the addition of these engines, John Deere will be able to offer marine customers heavier duty cycles* and a more comprehensive power range, from 298 up to 599 kW (400 up to 803 hp). Production is anticipated to begin in 2026.

“The vessels powered by our marine engines are part of hardworking, relentless commercial operations that need uncompromising power and reliability,” said Pierre Guyot, senior vice president of John Deere Power Systems. “With the JD14 and JD18 marine engines, we’re able to deliver high performance and excellent fuel efficiency while providing the rugged durability our marine engines have become known for in the industry. We’re thrilled to demonstrate our commitment to the marine industry through these new engines and to serve a new power class.”

The JD14 marine engine — an ideal fit for passenger vessels, pilot boats, and various workboat and pleasurecraft applications — is a 13.6L, 6-cylinder engine with an anticipated power range from 298 up to 599 kW (400 up to 803 hp). The JD14 marine engine will feature a reduced package size compared to the John Deere 13.5L 6135SFM85. The JD18 marine engine unlocks new potential for marine customers in commercial
fishing, passenger vessel, and tugboat markets with its 18.0L displacement and anticipated power levels from 410 up to 599 kW (550 up to 803 hp). The JD18 engine 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.

Engines as Tough as the Marine Industry
To bring the JD14 and JD18 marine engines to market, John Deere built upon its clean-sheet industrial Next Generation Engine architecture and prioritized customer value at every stage of the design process. Customers selecting a JD14 or JD18 marine engine will have many new and improved features to look forward to, including:

• 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, keeping vessels at work on the
  water longer.

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

John Deere is known for its iconic agriculture equipment, and our engines are designed to keep farmers' equipment working hard in the fields,” explained Michael Lefebvre, manager – global marketing and product strategy. “People may not realize it, but commercial fishermen and farmers have a lot in common when it comes to their power needs, including heavy duty cycles, easy-to-service components, and optimized fuel economy.
Using our industrial engines as a strong foundation, we are proud to bring these tough power solutions to the marine market and to offer even more value to our customers.”
