Yanmar 4JH110 110HP Inboard Diesel Engine
Compact Marine Diesel Performance with Exceptional Reliability
The Yanmar 4JH110 110HP Inboard Diesel Engine is a powerful and fuel-efficient marine diesel engine engineered to deliver reliable performance, smooth operation, and long-lasting durability for sailboats, cruising yachts, fishing boats, and commercial marine applications. Built with advanced common rail fuel injection technology and compact marine engineering, this 4-cylinder inboard diesel engine produces 110 horsepower while maintaining excellent fuel economy, low emissions, and quiet operation in demanding marine environments.
Designed for modern recreational and commercial vessels, the Yanmar 4JH110 combines strong low-end torque, responsive acceleration, and dependable cruising performance with a compact footprint that simplifies installation in confined engine rooms. Its advanced electronic management system and proven Yanmar marine technology make it an ideal propulsion solution for boat owners seeking efficiency, reliability, and low operating costs.
The engine is powered by a robust 2.2-liter inline 4-cylinder diesel platform designed specifically for continuous marine operation. Delivering 110 horsepower at 3200 RPM, the engine provides smooth power delivery and excellent torque characteristics, allowing vessels to maintain efficient cruising speeds and reliable performance under varying load conditions.
The Yanmar 4JH110 features an advanced turbocharged and intercooled aspiration system that improves airflow efficiency and enhances combustion performance. The turbocharger increases intake air pressure to generate stronger power output and quicker throttle response, while the intercooler reduces intake air temperatures to improve combustion density, fuel efficiency, and engine durability during extended operation.
Equipped with Yanmar’s electronically controlled common rail direct injection system, the engine delivers highly precise fuel atomization and optimized combustion control. This advanced fuel system improves fuel economy, reduces exhaust emissions, lowers engine noise, and provides smoother operation compared to conventional mechanical diesel engines.
The integrated electronic engine management system continuously monitors engine performance and operating conditions to maximize efficiency and reliability. Electronic controls provide smooth throttle response, improved starting performance, and accurate engine diagnostics for easier maintenance and dependable long-term operation.
The freshwater cooling system with heat exchanger protection helps maintain stable operating temperatures while protecting internal engine components from corrosion in both freshwater and saltwater environments. Marine-grade corrosion-resistant materials and heavy-duty construction ensure reliable performance and long engine life in demanding offshore conditions.
Yanmar engineered the 4JH110 for smooth and quiet operation. Precision-balanced internal components, advanced combustion technology, and flexible engine mounting systems significantly reduce vibration and engine noise levels, creating a more comfortable onboard experience during long voyages and cruising activities.
The compact and lightweight engine design allows easier installation in sailboats and smaller engine compartments without sacrificing power or reliability. This makes the engine highly suitable for both new vessel construction and marine repower projects.
A high-output alternator system provides dependable charging power for onboard electronics, navigation systems, communication equipment, lighting, refrigeration, and battery banks. The engine also supports integration with modern marine displays and electronic monitoring systems for enhanced operational convenience.
The Yanmar 4JH110 complies with major international marine emissions and environmental standards including EPA Tier 3 and EU RCD regulations. Its modern diesel technology delivers environmentally responsible operation while maintaining outstanding fuel efficiency and marine performance.
Renowned for its durability, low maintenance requirements, and fuel-saving operation, the Yanmar 4JH110 110HP Inboard Diesel Engine is an excellent choice for boat owners and marine professionals seeking reliable diesel propulsion, efficient cruising performance, and proven Yanmar engineering quality.
