Description

Yanmar 6LP-DTE 250HP Marine Inboard Diesel Engine (Recon)

The reconditioned Yanmar 6LP-DTE 250HP marine diesel engine is a six-cylinder propulsion option for boat owners evaluating a replacement engine or an inboard repower. Its 4.163-litre platform, direct injection, turbocharger and intercooler provide the core specification of this Yanmar LP Series model.

MSS Motorsports UG offers this engine in reconditioned condition, with the proposed unit, work completed and included equipment to be identified in the quotation. Request current availability and pricing for an engine-only supply or an engine-and-gearbox package.

Yanmar 6LP-DTE Power and Configuration

The manufacturer’s original documentation lists 250 MHP (184 kW) at 3,800 rpm as maximum flywheel output and 210 MHP (154 kW) at 3,600 rpm as the continuous rating.

These are distinct operating ratings. For a replacement project, your installer should assess the engine against the vessel’s propulsion requirements, gearbox ratio, propeller loading and intended use.

The Yanmar 6LP-DTE 250HP is the inboard version; related DTZE designations identify sterndrive configurations. Use the complete engine model when comparing equipment and installation requirements.

Reconditioning Details That Matter

A reconditioned marine engine should be assessed by the work performed and the evidence available for the actual unit. Request a report identifying the components inspected, repaired or replaced, together with any available measurements and test results.

Ask what work covered the fuel injection equipment, turbocharger, intercooler, cooling system and exhaust components. Confirm any recorded hours before and after reconditioning, and request running-test or load-test information where available.

These records help your installer assess the engine’s condition and identify any additional preparation needed before installation.

Gearbox Matching and Installation

For a Yanmar 6LP-DTE 250HP engine and gearbox package, specify your required reduction ratio, shaft arrangement and existing transmission details.

If you intend to retain the current gearbox, provide its model, ratio and identification-plate photograph. Your installer should review transmission capacity, coupling, engine mounts, shaft alignment, exhaust routing and cooling connections.

Buyers comparing other Yanmar 6LP-DTE 250HP options can also review the Yanmar 6LPA-STC (Z) 315HP marine diesel engine, with its power rating and configuration assessed separately.

Included Equipment and Warranty

The written offer should identify the engine serial number and list the gearbox, instrument panel, wiring, mounts, exhaust equipment and accessories included in the price.

Request confirmation of the warranty provider, coverage period, covered components, exclusions and installation requirements. Packing, dispatch estimates and delivery terms should also be stated so you can budget for the complete supply.

Frequently Asked Questions

What does “Recon” mean for this engine?

It means the engine is offered as reconditioned. Request the unit-specific reconditioning report to establish the work completed and the components repaired or replaced.

Is 250HP the continuous rating?

No. The original manual lists 250 MHP as maximum output and a separate continuous rating of 210 MHP.

Is a marine gearbox included?

The quotation must confirm this. State whether you require an engine only or an engine-and-gearbox package, including the required reduction ratio.
