Description

New Cummins X15 400HP Diesel Engine For Sale

Looking for a new Cummins X15 400HP diesel engine for your next project? Contact MSS Motorsports UG to request pricing, availability, and the specifications of the proposed engine. The X15 belongs to Cummins’ 15-litre class diesel engine family, with six-cylinder construction, electronic engine management and XPI fuel injection.

For buyers planning a marine repower or inboard propulsion installation, confirming the exact engine configuration is the first step toward choosing a suitable package.

Understanding the Cummins X15 400HP Marine Engine Rating

Cummins publishes 400 HP / 298 kW ratings in its truck-focused Cummins X15 Efficiency Series specifications. This establishes the horsepower rating, but does not establish approval for marine propulsion.

The Cummins X15 marine propulsion datasheet lists marine propulsion ratings starting at 450 BHP. A 400HP unit therefore requires its own marine configuration documentation before its suitability, operating speed or duty rating can be confirmed.

For a marine enquiry, request the engine data plate, build specification and documented propulsion rating before placing an order.

Cummins X15 400HP Engine Technology

The published X15 Efficiency Series platform includes:

• Cummins XPI fuel injection: High-pressure fuel delivery with electronically controlled injection events.
• Electronic engine control: An ECM that manages engine operation and processes inputs from engine systems.
• Six-cylinder diesel construction: A heavy-duty engine platform offered in several power configurations.

The proposed unit’s build specification determines its turbocharger, cooling arrangement, emissions equipment and controls. Use that specification when comparing packages and planning installation costs.

Technical Information

Marine Repower and Gearbox Selection

For a fishing vessel, workboat or other commercial marine project, match the engine package to the vessel’s operating requirements. Daily running hours, time at full load, target speed and propulsion arrangement help determine the appropriate marine duty rating.

Gearbox selection also requires more than a horsepower match. Confirm the engine’s torque curve, rated speed, flywheel housing, reduction ratio and the transmission’s approved duty capacity. ZF Marine or Twin Disc gearbox compatibility must be checked for the specific engine and transmission combination.

If your project requires a documented X15 marine rating, compare the Cummins X15 450HP inboard diesel engine, subject to confirmation of the available build and vessel requirements.

Specify the Package Before You Buy

Request a quotation that identifies:

• The engine serial number, build details and supporting documentation.
• Whether the supply includes an engine only or an engine and gearbox package.
• Included controls, wiring, cooling equipment and installation accessories.
• Applicable warranty provider, coverage, exclusions and commissioning requirements.
• Availability, dispatch estimate, freight costs and delivery terms.

A clearly specified package makes it easier to compare offers and budget for installation. Fuel consumption and maintenance requirements should be assessed using data for the approved configuration and your operating profile.

Frequently Asked Questions

Is the Cummins X15 400HP a factory-rated marine engine?

The manufacturer information reviewed confirms 400HP on-highway ratings. Marine suitability requires separate documentation for the exact engine offered.

Does a new engine automatically include a Cummins marine warranty?

Warranty eligibility depends on the engine, supply route, and approved application. Obtain written confirmation of coverage before purchase.

Can I order the engine with a marine gearbox?

Include your preferred gearbox model and reduction ratio in the enquiry. Compatibility and package availability must be confirmed before ordering.
