JD18P

Marine Propulsion Engine

Features

High-pressure common-rail (HPCR)

Provides more flexible injection timing and higher efficiency. Rear gear train and HPCR reduces noise by up to 3 decibels.

4-valve cylinder head

Excellent airflow through 4-valve cylinder head delivers greater low-speed torque and better transient response time.

Water-cooled exhaust manifold

Integrated components eliminate external hoses and fittings. Wet exhaust manifold creates a cooler and quieter environment for passengers and crew.

Turbocharged, air to coolant cooled with separate circuit

Cooler turbocharger operation enables higher ratings and efficiencies for applications that require high power or speed.
Jacket water cooling system with separate circuit to assure salt water can't enter the combustion system.

Hydraulic automatic valve lash adjustment

Extended service intervals

Longer service intervals with use of John Deere oil. Rigid bronze impeller on sea water pump with up to 10 000-hour life before needing maintenance.

John Deere Connected Support™

Remote monitoring and diagnostics comes standard. Provides protection and efficiency with no subscription fees or ongoing expenses.
