The Yanmar 4LV Series is a modern common-rail marine diesel engine range developed for large sailing yachts, superyacht tenders, motorboats and light-duty commercial vessels. Its compact four-cylinder design combines a 2.8-litre displacement with strong low-speed torque, responsive acceleration and low levels of noise and vibration. The range is suitable for both new vessel installations and carefully planned marine repower projects.
Five power ratings are available within the series. The Yanmar 4LV150 delivers 150 MHP, while the Yanmar 4LV170 and Yanmar 4LV195 provide 170 MHP and 195 MHP respectively. Higher-output options include the Yanmar 4LV230 at 230 MHP and the Yanmar 4LV250 at 250 MHP. These named models allow buyers to compare different outputs within the same engine platform and provide relevant product-page opportunities for internal linking.
Selecting the correct Yanmar 4LV marine engine requires the vessel’s displacement, hull form, propulsion arrangement, desired cruising performance and operating duty to be assessed. The 4LV150, 4LV170 and 4LV195 are rated at 3,500 rpm, while the 4LV230 and 4LV250 are rated at 3,800 rpm. Installation dimensions, engine-room ventilation, cooling-water supply, exhaust routing, engine mounts and propeller demand must also be reviewed before ordering.
A Yanmar 4LV engine package can be configured for shaft drive, jet drive or the Yanmar ZT370 sterndrive, subject to the requirements of the selected model and vessel. Electronic operation is available through the Yanmar VC10 Vessel Control System, with mechanical controls offered as an option. Buyers should confirm the marine gearbox, reduction ratio, control stations, instrument display, wiring harness, engine mounts, exhaust components and other included accessories in writing.
When requesting a Yanmar 4LV engine for sale, provide the vessel type, required horsepower, current engine and drive system, intended operating duty, propeller details, installation dimensions and delivery destination. The quotation should identify the exact 4LV model, condition, rated output, drive or gearbox configuration, included components, exclusions, warranty, availability, lead time, packing method and delivery terms.
