Dimensions
Features and Benefits
High-Pressure Common Rail Fuel System
- Variable injection pressure and timing control
4-valve Cylinder Head
- New cylinder head with 4-valve design provides increased air flow resulting in higher low speed toque and better transient response time
John Deere Electronic Controls
- Built in controls eliminates the need for costly add on engine warning systems and associated components stored for later retrieval and ease of diagnostics
- Built in engine synchronization feature
Watercooled Turbocharger and Exhaust
Manifold
- Cooler and quieter environment for vessel and crew
- Reduced external connection eliminates hoses an fittings that can leak or break
Replaceable Wet-type Cylinder Liners
- Excellent heat dissipation
- Hardened and precision machined for long life
- Rebuild to original specifications
High Torque and Low Rated RPM
- Excellent vessel control and maneuvering
- Lower rated rpm limits vibration and noise
Cooling System
- High-capacity heat exchanger designed for reliable operation in adverse conditions
- Available as keel cooled
Corrosion Resistant Components
- Provides engine protection from the effects of seawater
Centered, Vertical Injectors
- Engines burn cleaner, resulting in lower emission and improved fuel economy with the aid of vertical injectors
High Power Density
- High power density offers more power in a smaller package
Additional Features
- Either side service
- Optional auxiliary drive
Applications
- Generator drive engines, propulsion, and auxiliary
