Yanmar 6CX-ETE Marine Inboard Diesel Engine 375HP
The Yanmar 6CX-ETE 375HP marine inboard diesel engine combines 7.127-litre displacement, six-cylinder construction, turbocharging and intercooling with a published 375HP continuous rating at 2,600 rpm. It is a Yanmar CX Series propulsion option for buyers assessing a replacement engine or a vessel repower.
MSS Motorsports UG offers the Yanmar 6CX-ETE with pricing, availability and supply details confirmed for the actual engine proposed. Send your vessel and drivetrain requirements to request an engine-only quotation or discuss an engine-and-gearbox package.
Yanmar CX Series Marine Diesel Power
The Yanmar 6CX-ETE 375HP uses direct injection with an in-line fuel injection pump and freshwater engine cooling. Its turbocharger and air cooler form part of the documented marine engine configuration.
For a motor cruiser, fishing vessel or workboat project, assess the engine against the boat’s required power, operating profile and propulsion arrangement. For an existing 6CX-ETE installation, comparing the replacement with the original engine can help your installer define the scope of the work.

Gearbox Selection and Repower Planning
For a Yanmar 6CX-ETE 375HP engine and gearbox package, specify the required reduction ratio, shaft arrangement and intended operating duty. The factory-documented YX-70S ratios provide reference points; the actual transmission supplied must be identified in the written offer.
If you plan to retain an existing gearbox, provide its model, ratio and identification-plate photograph. Your installer should review transmission capacity, coupling, shaft alignment, mounting positions, cooling connections and exhaust routing.
For another Yanmar propulsion option, explore the Yanmar 6LY400 marine inboard diesel engine and compare its specification against your vessel’s requirements.
Engine Condition, Included Equipment and Warranty
For this earlier-generation engine, request the serial number, recorded hours and any available maintenance, inspection or refurbishment records. Where available, running-test information can support your installer’s assessment.
A clearly specified quotation should identify the gearbox, controls, instrument panel, wiring, mounts and accessories included in the price. It should also confirm any applicable warranty, its provider and coverage terms, together with packing, dispatch and delivery details.
