Yanmar 4JH110 Marine Diesel Engine 110 HP
The Yanmar 4JH110 Marine Diesel Engine 110 HP is a high-performance, four-cylinder inboard diesel engine developed for sailing yachts, motor sailers, recreational cruising vessels, and compatible marine repowering projects.
Producing 110 metric horsepower (80.9 kW) at 3,200 RPM, the Yanmar 4JH110 combines a compact 1.995-litre diesel engine with Bosch common-rail direct fuel injection, turbocharging, charge-air cooling, and electronic engine management.
Part of the respected Yanmar JH-CR Series, the 4JH110 offers substantial propulsion power from a relatively lightweight engine platform. Its compact construction and multiple transmission options make it an attractive choice for larger sailing yachts and other appropriately matched recreational vessels.
The engine is available with approved marine gearboxes and saildrive arrangements, allowing customers to select a propulsion system suited to their vessel’s installation requirements.
At JB Marine GmbH, customers can enquire about the Yanmar 4JH110, including engine-only configurations, compatible marine gearboxes, saildrive packages, controls, installation accessories, and international shipping.
Why Choose the Yanmar 4JH110?
Powerful 110 HP Four-Cylinder Performance
The Yanmar 4JH110 develops 80.9 kW (110 mhp) at 3,200 RPM, making it the highest-output model in the standard Yanmar JH-CR engine series.
Its four-cylinder configuration delivers substantial power for vessels requiring stronger propulsion than smaller auxiliary sailing engines can provide.
The engine is suitable for appropriately matched larger sailing yachts, motor sailers, and recreational cruising vessels.
Advanced Bosch Common-Rail Fuel Injection
The Yanmar 4JH110 uses an electronically controlled Bosch common-rail direct-injection system.
The system precisely manages fuel delivery according to engine operating conditions.
Advantages include:
- Accurate fuel injection control
- Responsive throttle operation
- Smooth engine performance
- Efficient combustion
- Electronic engine monitoring
- Controlled fuel delivery
Correct fuel quality and regular fuel-filter replacement remain essential for reliable operation.
Turbocharged and Intercooled Performance
The 4JH110 uses turbocharging with charge-air cooling.
The turbocharger increases combustion-air delivery, while the intercooler helps reduce compressed-air temperature.
This arrangement supports the engine’s 110 HP output from its compact two-litre displacement.
Benefits include responsive acceleration and effective power delivery across the intended operating range.
Compact and Lightweight Construction
One of the advantages of the Yanmar 4JH110 is its compact design.
The manufacturer’s published dry engine weight is approximately 229 kg without the marine gearbox.
This can be beneficial when planning engine replacements, engine-room layouts, and weight-sensitive sailing yacht installations.
The published overall dimensions with the KM4A2 gearbox are approximately 909 × 613 × 675 mm.
Actual dimensions depend on the selected transmission and exhaust arrangement.
Freshwater Cooling with Heat Exchanger
The Yanmar 4JH110 uses freshwater cooling with a seawater-cooled heat exchanger.
Freshwater coolant circulates through the engine, while seawater removes heat through a separate cooling circuit.
Routine maintenance should include inspection of:
- Engine coolant
- Seawater pump and impeller
- Heat exchanger
- Cooling hoses
- Seawater intake and strainer
- Charge-air cooling components
Correct cooling-system maintenance is essential for dependable diesel operation.
Flexible Gearbox and Saildrive Options
The Yanmar 4JH110 supports several manufacturer-documented propulsion arrangements.
These include:
- KM4A2 marine gearbox
- KMH4A marine gearbox
- KMH50V-2 V-drive
- Selected ZF marine gearboxes
- Yanmar SD110 saildrive
This flexibility makes the engine suitable for different installation layouts, provided the transmission is correctly matched to the vessel.
Modern Electronic Controls
The Yanmar 4JH110 uses electronic engine management while retaining a standard mechanical throttle-control arrangement.
Optional compatible Yanmar vessel control equipment provides additional electronic helm integration.
Depending on configuration, available features may include:
- Engine monitoring
- Digital instrumentation
- Electronic throttle and shift
- Multiple helm stations
- Compatible NMEA 2000 monitoring
- Engine alarms
- Additional vessel-control functions
The exact features depend on the control-system generation and installed accessories.
