Request Yanmar 8LV320 320HP pricing from MSS Motorsports UG for your proposed installation. Specify whether you require an engine-only replacement or an engine and gearbox package, together with the controls and accessories needed for your vessel.
Compact Common Rail V8 Propulsion
The Yanmar 8LV320 320HP is the starting output in Yanmar’s 320–370 MHP 8LV Series. The manufacturer describes the V8 platform as smooth-running and responsive, with an operating range extending from approximately 550 rpm at idle to 3,800 rpm at maximum rated output. YANMAR Marine International
For motor cruisers, recreational sportfishing boats and yacht tenders, its suitability depends on the hull’s power requirement, installation space and intended operating profile.
Key features include:
- Denso common rail injection: Electronically controlled direct fuel injection.
- Twin turbochargers with intercooling: Supports acceleration response and rated power.
- V8 configuration: A compact arrangement to assess against your engine-room layout.
- 12V / 180A alternator: Manufacturer-listed charging equipment.
- 435 kg dry weight without gearbox: Installed weight increases with the transmission, fluids and accessories. YANMAR Marine International

MHP means metric horsepower. The advertised 320HP figure is maximum crankshaft output. The published continuous rating and the power reaching the propeller through the drivetrain are separate figures.
Confirm the Operating Duty
Yanmar’s standard 8LV operation manual identifies recreational use. Its current light-duty commercial warranty documentation separately names 8LV320(Z)C variants among applicable models. For commercial service, confirm the full model designation, approved duty and required emissions documentation for the exact engine offered. yanmar.com
The engine’s rating must suit the intended workload. Include expected annual operating hours and typical cruising requirements when discussing a new installation or repower.
Inboard Gearbox and Electronic Controls
Yanmar documents KMH50A and KMH52V marine gearbox configurations for the 8LV family. The KMH50A uses an 8-degree down-angle arrangement with hydraulic shift. The selected gearbox and reduction ratio must match engine input speed, shaft geometry and propeller loading. www.yanmar.com
The manufacturer lists VC10 and VC20 vessel control systems among compatible products. Confirm the control generation, instruments, wiring harnesses and number of helm stations included in the quotation. YANMAR Marine International
For a shaft-drive installation, specify the 8LV320 inboard configuration. The 8LV320Z is the sterndrive version and requires the corresponding drive-specific equipment. www.yanmar.com
Review the official Yanmar 8LV320 specifications and technical documents for manufacturer reference information.
If your vessel requires another output, compare the Yanmar 8LV350 common rail marine diesel engine. Select the engine around the complete propulsion requirement.
Establish Your Engine Supply Package
When comparing a Yanmar 8LV320 engine for sale, request an itemised quotation confirming:
