Common Rail V8 Power for Recreational Boats

The 8LV350 sits between the 320 MHP and 370 MHP models in Yanmar’s 8LV Series. Yanmar 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, the engine can be considered where the hull’s power requirement and installation layout suit its specifications.

Key features include:

  • Denso common rail direct injection: Electronically controlled fuel delivery.
  • Twin turbochargers and intercooling: Supports acceleration response and rated power.
  • Compact V8 configuration: A layout to assess against available engine-room space.
  • 12V / 180A alternator: Manufacturer-listed charging equipment.
  • 435 kg dry engine weight: Excludes the gearbox, fluids and installation accessories. YANMAR Marine International

MHP means metric horsepower. The advertised 350HP figure describes maximum crankshaft output. The continuous rating and the power reaching the propeller through the drivetrain are separate figures.

Select the Correct Duty Rating and Version

Yanmar’s standard 8LV operation manual identifies recreational use. Its current light-duty commercial warranty documentation separately names 8LV350(Z)C variants among applicable models. Commercial buyers should confirm the full model designation, approved operating duty and required certification for the particular engine offered. yanmar.com

For shaft-drive installations, specify the 8LV350 inboard arrangement. The 8LV350Z is the sterndrive version and requires the corresponding drive-specific equipment. Confirm the complete configuration before placing an order. www.yanmar.com

Review the official Yanmar 8LV350 specifications and technical documents for manufacturer reference information.

Gearbox and Electronic Helm Integration

Yanmar documents KMH50A and KMH52V marine gearbox configurations for the 8LV family. The KMH50A uses an 8-degree down-angle arrangement with hydraulic shift. Gearbox selection must account for engine input speed, reduction ratio, shaft position and propeller loading. www.yanmar.com

The manufacturer also lists VC10 and VC20 vessel control systems among compatible products. Ask your quotation to identify the control generation, displays, wiring harnesses and number of helm stations included. YANMAR Marine International

For another output within the same family, compare the Yanmar 8LV370 common rail marine diesel engine. Confirm duty and certification separately for each model.
