The Yanmar 8LV370 (Z) 370HP inboard diesel engine is a high-output marine diesel built around a compact V8 architecture, twin-turbocharged air handling and a Denso common rail fuel system. Yanmar rates the engine at 272 kW / 370 MHP at 3,800 rpm, with a 4.46-liter displacement and eight cylinders. The 8LV series is designed for recreational marine propulsion and is available in both inboard and sterndrive configurations, making the 8LV370 relevant to performance-oriented repowers and new marine installations.
Yanmar’s current specifications list a 12V 180A alternator, electronic controls, flexible mounting and a dry weight of 435 kg (959 lb) without gear. The published dimensions are 1,340 × 880 × 766 mm, with the stated dimensional configuration including the KMH50A gearbox and standard mixing elbow. Exact installation dimensions can change with the selected gear, exhaust elbow and propulsion configuration, so vessel compatibility should be confirmed before ordering.
The 8LV370 is the highest-output model in Yanmar’s 8LV 320–370 MHP range. Yanmar’s current product information describes the series as a compact power plant using a V8 common rail configuration and twin turbos. The broad operating range extends from approximately 550 rpm idle to 3,800 rpm maximum rated speed, providing a combination of low-speed maneuvering capability and high-output propulsion.
The engine’s twin-turbo arrangement is designed to provide strong torque response and acceleration, while the common rail fuel system provides electronically managed fuel delivery. The 8LV platform also uses a large 180A alternator as standard, supporting the electrical demands of modern recreational vessels when correctly integrated with the boat’s electrical system.

Yanmar states that its published dimensions include the KMH50A gearbox with the standard mixing elbow for the specified configuration. The manufacturer also provides a separate dimensional measurement for through-drive exhaust without the sterndrive, and notes that dimensions may vary with other gears or exhaust elbows. Installation planning should therefore use the dimensions for the exact engine and drive package being purchased.
The Yanmar 8LV370 uses direct injection with a Denso Common Rail System. Common rail injection allows the engine management system to control fuel delivery electronically, while the twin-turbocharged and intercooled air system supports the engine’s high-output configuration.
For a repower, fuel-system planning should include the vessel’s fuel quality, filtration, supply and return arrangements, as well as the installation requirements for the selected engine package. Follow the current Yanmar installation and service documentation for the exact configuration rather than adapting fuel-system components solely from the previous engine.
The 8LV370 combines a V8 cylinder layout with twin turbochargers and intercooling. Yanmar’s 8LV series information identifies the V8 common rail design as a key part of the platform’s smooth-running and high-output characteristics. The 8LV370’s 4.46-liter displacement and 370 MHP rating place it in the high-power recreational marine diesel segment.
The engine’s 90-degree V8 configuration also provides a compact power unit relative to its output. Yanmar positions the 8LV series for both new builds and repowers, subject to the vessel’s propulsion requirements, installation space and selected gear or sterndrive arrangement.
A 12V 180A alternator is part of the Yanmar 8LV370 specification. This high-capacity charging output can support onboard electrical equipment and battery charging while the engine is operating, subject to the vessel’s complete electrical architecture.
The engine is electronically controlled and can integrate with Yanmar’s VC10 vessel control system. Yanmar also lists NMEA 2000 engine monitoring as an optional accessory. Confirm the required displays, harnesses, monitoring equipment and network connections for the exact vessel installation before ordering.
The 8LV370 is available with different propulsion arrangements. Yanmar’s published specifications reference the KMH50A gearbox for inboard configurations, while the ZT370 hydraulic sterndrive is designed for compatible 8LV installations. The ZT370 uses a hydraulic multiple friction-plate clutch and is rated for 370 MHP / 272 kW.
The correct drive arrangement depends on the boat’s existing propulsion system and intended installation. When replacing an existing engine, compare transmission or sterndrive compatibility, reduction ratio, shaft alignment, exhaust routing, steering requirements, mounting points and propeller specifications before finalizing the engine package.
The 8LV370 uses electronic controls and is designed around Yanmar’s vessel-control architecture. The VC10 system can provide electronic management of engine and propulsion functions, while compatible Yanmar equipment can support engine monitoring and vessel integration.
Optional equipment listed for the 8LV370 includes extension harnesses, second-station equipment, NMEA 2000 engine monitoring, hot-water connections, water separation equipment, power-steering components, exhaust cooling-water bypass equipment and an engine oil drain pump. The exact equipment supplied depends on the selected package.
Yanmar’s published 8LV370 information identifies standard package components including a 12V 180A alternator, flexible mounts and fresh-water expansion tank. Exhaust and power-steering equipment varies between inboard and sterndrive configurations. Verify the actual sales package and included components before ordering.
The 8LV370 is a substantial 370 MHP propulsion engine, so installation should be evaluated as a complete propulsion-system project. Check engine-bed dimensions, mounting positions, transmission or sterndrive compatibility, exhaust routing, cooling connections, fuel-system requirements, electrical connections, steering equipment and access for routine maintenance.
The manufacturer’s published dry weight is 435 kg without gear. The installed propulsion package will weigh more after adding the selected gearbox or sterndrive, mounts, fluids and associated equipment. Confirm the resulting weight distribution and structural requirements with the vessel manufacturer or qualified marine installer.
The Yanmar 8LV370 is intended for recreational marine applications where approximately 370 MHP of diesel propulsion is required. It can be considered for high-performance powerboats, larger recreational vessels and repower projects where the vessel’s propulsion system is designed around the engine’s output and installation requirements.
Buyers comparing high-output inboard diesel engines should evaluate more than horsepower alone. Important factors include continuous and maximum output, engine weight, dimensions, transmission or sterndrive compatibility, fuel system, cooling system, electrical output, control architecture and service access. These details determine whether an engine is suitable for a particular hull and repower project.
If you are comparing the Yanmar 8LV370 with other marine propulsion options, explore our inboard marine engines category. Compare horsepower, displacement, engine configuration, dimensions, weight, fuel system and drive options before selecting an engine for a new build or repower.
