Bosch Common-Rail Injection and Electronic Controls

The 6LT500 uses direct injection with a Bosch common-rail fuel system. Its electronic management controls fuel injection, while the turbocharger and intercooler provide boosted, cooled intake air.

Yanmar lists VC20/VC30 vessel control packages for this model, with electronic CAN-bus helm equipment and instrumentation. For a replacement project, specifying the controls alongside the engine helps establish the full repower scope.

Other manufacturer-listed features include a 24V electrical system, 90A alternator and heat-exchanger cooling. Confirm the equipment fitted to the specific engine quoted. YANMAR Marine International

Technical Specifications

Rating note: Yanmar states horsepower as metric horsepower (MHP). Match the engine’s documented duty to the intended operating hours and load profile. YANMAR Marine International

Consult the official Yanmar 6LT500 specifications for manufacturer reference data.

Vessel Applications and Repower Planning

Yanmar positions the 6LT family for planing and semi-planing hulls, fast boats and suitable light-duty commercial installations. For the 6LT500, assess the vessel’s displacement, target cruising speed and propeller demand alongside its operating duty. YANMAR Marine International

A repower quotation should account for engine-room access, mounting arrangements, cooling-water connections, exhaust routing and service clearances. If you intend to retain existing equipment, provide its identification and installation photographs.

For a higher-output option in the same family, compare the Yanmar 6LT580 marine inboard diesel engine.

Marine Gearbox and Helm Options

Yanmar’s operation manual identifies ZF305-3 and ZF305-3A marine gearboxes for the 6LT range. Product documentation also lists angled, parallel and V-drive gearbox options.

The correct transmission and reduction ratio depend on the shaft arrangement, vessel load and propeller calculation. Your installer should confirm the proposed engine-and-gearbox combination.

Specify the required VC20 or VC30 control package, helm stations, display and harnesses. Additional monitoring or joystick equipment should be identified separately in the quotation where required. yanmar.com
