Yanmar 4JH4-TE 75 HP – Turbocharged Marine Inboard Power

Overcoming the limitations of naturally aspirated engines in heavy head-seas, the Yanmar 4JH4-TE delivers a potent 75 HP at 3200 RPM. This 2-liter turbocharged unit is a favorite for American boaters with heavy-displacement sailboats and mid-sized trawlers who require extra thrust for navigating tidal currents and offshore transits. Its compact in-line 4-cylinder design provides a high power-to-weight ratio, ensuring that American owners can upgrade their propulsion without sacrificing valuable engine room accessibility.

Adhering to EPA emission standards for its class, the 4JH4-TE focuses on mechanical durability and high thermal efficiency for the American maritime market. The freshwater cooling system and high-efficiency turbocharger are engineered for long-duty cycles in the warm waters of the American South. For the USA boater, the integrated 80A alternator ensures reliable charging for house batteries and navigation electronics, making it a dependable partner for long-range cruising from the Chesapeake Bay to the Florida Keys.
