For boatbuilders and repower owners seeking 300-plus horsepower without moving to a large inline-six engine, the Yanmar 8LV Series offers a compact V8 alternative. Its balanced configuration, responsive power delivery and relatively low installation weight suit performance motor yachts, sportfishing boats, superyacht tenders and other fast recreational or light-duty commercial vessels.
Power rises in three measured steps across the range. The Yanmar 8LV320 delivers 320 MHP (235 kW), the Yanmar 8LV350 produces 350 MHP (257 kW), and the Yanmar 8LV370 reaches 370 MHP (272 kW). All three models share a 4.46-litre displacement and a rated speed of 3,800 rpm, allowing buyers to choose the required output without changing to a different basic engine architecture.
A Denso common-rail injection system, twin turbochargers and intercooling define the performance character of these Yanmar V8 marine engines. The operating range extends from approximately 550 rpm at idle to 3,800 rpm at maximum rated speed, supporting controlled low-speed manoeuvring and rapid acceleration. A standard 12-volt, 180-amp alternator also provides useful capacity for modern onboard electrical systems.
Propulsion flexibility is one of the 8LV range’s strongest advantages. The engines can be configured for shaft drive, jet drive or the Yanmar ZT370 sterndrive, with electronic VC10 control and model-compatible joystick options available. JC10 supports applicable twin-sterndrive installations, while JC20 is intended for compatible twin-shaft arrangements. Commercial buyers considering the 8LV370 must verify certification because Yanmar states that this model is not EPA Commercial certified.
To obtain an accurate Yanmar 8LV engine price, provide the vessel model, hull type, existing propulsion system, required horsepower, operating duty, installation dimensions and destination. The resulting quotation should identify whether the offer is for the 8LV320, 8LV350 or 8LV370, together with the drive or gearbox, controls, displays, steering equipment, mounts, exhaust components, warranty, commissioning requirements and delivery schedule.
