V8 Performance for Cruising and Manoeuvring
Yanmar positions the 8LV Series around responsive acceleration, smooth running and a broad operating range. Its approximately 550 rpm idle speed supports low-speed manoeuvring, while maximum rated output is reached at 3,800 rpm. YANMAR Marine International
The compact V8 layout makes the 8LV370 a candidate for motor cruisers, recreational sportfishing boats and yacht tenders, subject to a vessel-specific installation assessment.
Key features include:
- Denso common rail injection: Electronically controlled, high-pressure direct fuel injection.
- Twin turbochargers with intercooling: Supports the engine’s power delivery and acceleration response.
- Electronic engine management: Provides a basis for integrated helm controls and instrumentation.
- 12V / 180A alternator: Published charging equipment for the model.
- 435 kg dry engine weight: Excludes the marine gearbox, fluids and installation equipment. YANMAR Marine International

MHP means metric horsepower. The advertised 370HP figure is maximum crankshaft output. The lower continuous rating and the power delivered to the propeller are separate measurements.
Shaft-Drive Gearbox and Helm Options
For an 8LV370 inboard propulsion package, Yanmar documentation includes the KMH50A marine gearbox, with an 8-degree down-angle arrangement and hydraulic shift. The manufacturer also documents KMH52V gearbox configurations. yanmar.com
The selected gearbox, reduction ratio and propeller must suit the hull, engine speed and shaft arrangement. Existing transmissions require compatibility checks before reuse.
Yanmar lists VC10 and VC20 vessel control systems among the model’s compatible products. Confirm the control generation, displays, harnesses and number of helm stations supplied. Joystick operation requires the appropriate compatible installation and equipment. YANMAR Marine International
Confirm the Drive Version and Operating Duty
The 8LV370 inboard arrangement and 8LV370Z sterndrive arrangement require different installation planning. Specify the complete model and drive configuration when requesting a replacement engine. yanmar.com
Yanmar’s operation manual identifies recreational use, and the manufacturer states that the 8LV370 is not EPA Commercial certified. Any proposed commercial installation requires confirmation of the appropriate duty rating, emissions documentation and application approval. yanmar.com
Review the official Yanmar 8LV370 specifications and technical documents for manufacturer reference information.
For a lower-output model within the same family, compare the Yanmar 8LV350 common rail marine diesel engine.
Define Your Repower and Supply Package
