Yanmar 4JH110 – Marine Diesel Engine 110 HP

Description

Using common rail injection with 110 hp at 3,200 rpm, the Yanmar 4JH110 combines turbocharged and intercooled induction with a 1.995L inline four-cylinder diesel platform. The engine uses EN 590 diesel and a stated 17.0:1 compression ratio. Mechanical or hydraulic transmission options, KM4A2 or ZF30M drive compatibility, and electronic-control compatibility shape the documented propulsion-system configuration.

The 505-pound dry engine uses an SAE 4 flywheel housing and a 12V 125-amp alternator. Enclosed forced lubrication holds 5.0L oil, while heat-exchanger cooling uses 7.2L coolant and the wet mixing elbow forms part of the exhaust system. Listed emissions ratings include EPA Tier 3, RCD II, and BSO II.

Key Specifications of the Yanmar 4JH110 Marine Diesel Engine

• The 1.995L inline four-cylinder engine produces 110 hp at 3,200 rpm through turbocharged and intercooled common rail diesel operation.
• Common rail injection and EN 590 fuel requirements define the documented fuel-system specification for the stated 17.0:1 compression ratio.
• KM4A2 and ZF30M drive options require drivetrain compatibility review before selecting a replacement propulsion package.
• Mechanical or hydraulic transmission choices pair with the SAE 4 flywheel housing for documented vessel-propulsion interface planning.
• A 12V 125-amp alternator provides the stated charging output for vessels using this engine electrical-system configuration.
• Heat-exchanger cooling holds 7.2L coolant, while the wet mixing elbow defines the specified exhaust-water arrangement.
• Enclosed forced lubrication uses 5.0L oil capacity, supporting planned service access within the engine-room maintenance schedule.

Engine Configuration and Service Access

This Yanmar marine diesel engine uses 84 by 90 mm bore and stroke dimensions in a four-stroke inline four-cylinder layout. Common rail fuel components, turbocharger, intercooler, heat exchanger, alternator, and wet-exhaust connection should remain accessible after installation.

Electronic-control compatibility is specified for this engine. The selected controls, transmission, propeller or shaft arrangement, fuel system, cooling plumbing, exhaust routing, and electrical connections should be planned as one complete propulsion installation.

Why Choose the Yanmar 4JH110 Marine Diesel Engine

The 4JH110 marine diesel engine combines 110 hp output with common rail injection, turbocharging, and intercooling in a 1.995L four-cylinder configuration. Buyers can assess its 12V 125-amp alternator, electronic-control compatibility, mechanical or hydraulic transmission options, and KM4A2 or ZF30M drive interfaces. EPA Tier 3, RCD II, and BSO II ratings provide additional technical context for this documented engine specification.

Installation and Compatibility Considerations

Confirm the vessel supports the 505-pound dry weight, SAE 4 flywheel housing, selected mechanical or hydraulic transmission, and KM4A2 or ZF30M drive configuration. Plan engine mounts, shaft alignment, fuel supply, turbocharger and intercooler clearance, cooling-water intake, wet-exhaust routing, electronic controls, 12V charging wiring, and ventilation before installation.

Use fuel meeting EN 590 requirements and allow access for the common rail system, 5.0L lubrication capacity, and 7.2L cooling capacity. Verify electronic-control compatibility and follow the applicable installation, commissioning, and maintenance documentation for the complete propulsion package.
