“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,” said Pierre Guyot, senior vice president, John Deere Power Systems.

The 13.6 L JD14 six-cylinder engine has an anticipated power range from 298 up to 599 kW (400 up to 803 hp) and is targeted to passenger vessels, pilot boats and various workboat and pleasure craft applications. The JD14P model will range from 298 to 448 KW (400-600 hp) and the JD14X model will be rated 523 up to 599 kW (700-803 hp). The company said the engine will have a reduced package size compared to the John Deere 13.5 L 6135SFM85.

The 18.0 L JD18 will offer anticipated power levels from 410 to 599 kW (550 to 803 hp), with up to 522 kW (700 hp) of uninterrupted power at the M1 rating and up to 599 kW (803 hp) at the M2 rating. The engine is targeted to commercial fishing, passenger vessel and tugboat applications.

In addition to the M propulsion ratings, John Deere said both engines will be available with variable-speed auxiliary and constant-speed auxiliary and generator ratings.

The JD14 and JD18 are based on a clean-sheet industrial Next Generation Engine architecture. They will incorporate new and improved features that include:

• A high-pressure common-rail (HPCR) fuel system;
• Rear gear train that provides up to two rear PTOs and capacity for auxiliary power;
• Overhead camshaft design and hydraulic lash adjusters;
• Higher duty cycle and up to a 500-hour extended fluid service interval.

The engines will be IMO Tier 2, EPA Tier 3 and EU RCD II certified. They will also be compatible with renewable diesel and biofuel blends.

Production of the new engines is expected to begin in 2026.
