What This Engine Is Built For
MEP Power supplies the Cummins 6CTAA8.3-M260 as a complete 6-cylinder in-line marine diesel engine of 8.3 L running a 114 * 135 mm bore and stroke. It is rated at 190 kW (260 HP) at 109kW/284HP @ 2200 rpm and develops 1125 N.m @ 1200 rpm. The engine is turbocharged/air-air cooled, with a Weifu PW2000 Pump/ RQV-K Governor fuel system. It is built at the Dongfeng Cummins Plant 6CTAA8.3-M260 and carries CCS Certificates. Typical duty is propulsion and auxiliary duty on workboats, fishing vessels, tugs and barges; dry weight with flywheel and alternator is 674 Kg and the overall envelope is 1360mm*780mm*988mm.
Key Benefits
- Delivers 190 kW (260 HP) at 109kW/284HP @ 2200 rpm from 8.3 L as a factory-rated assembly.
- Peak torque of 1125 N.m @ 1200 rpm holds the load without downshifting or derating.
- Turbocharged/Air-air cooled induction keeps charge temperature under control in continuous duty.
- Supplied to CCS Certificates, so the unit can be registered in markets that require it.
- Dry weight 674 Kg and envelope 1360mm*780mm*988mm are published so the installation can be checked before ordering.
- Published fuel consumption of ≤ 58.3 L/hr 6CTAA8.3-M260 makes running cost predictable.
Application Scenarios
- Main propulsion in a steel workboat
- Auxiliary and deck machinery drive
- Fishing vessel repower
- Harbour tug and pilot boat service
Who It Is For
- Shipyards repowering workboats and fishing vessels
- Boat owners replacing a worn main engine without changing the engine bed
- Marine service yards that keep exchange engines on the shelf
- Fleet operators standardising on one Cummins family across several hulls
Problems It Solves
- A vessel out of service earns nothing, and a mismatched replacement engine means new mounts, new couplings and weeks of yard time.
- Marine duty punishes engines that were never cooled for sea water service.
- Spare parts for grey-import engines are hard to identify years later.
- Identifying the right 6CTAA8.3-M260 variant from a serial number takes experience; MEP Power checks the configuration before quoting.

Use and Installation Guide
- Quote the model 6CTAA8.3-M260 and the engine configuration number D413065MX03 when ordering so the correct variant is supplied.
- Check the gearbox reduction ratio and propeller match before ordering
- Confirm raw-water or keel cooling to suit the hull
- Commission with the exhaust system and sea water pump connected as supplied
- Keep the warranty terms in mind: one year or 1000 hours, whichever comes first.
Customisation Options
- OEM and ODM builds, including your logo and company name on the unit
- Cummins engine customisation and modification to your requirement
- Mining and special explosion-proof builds
- Genuine or OEM parts specified on the quotation
How It Compares
| Compared with | What to consider |
|---|---|
| A rebuilt or used engine of the same rating | A rebuilt unit may show the same 190 kW (260 HP) on paper, but its running history is unknown and the warranty rarely covers the whole engine. |
| A larger engine in the same 6CTAA8.3 range | Moving up a frame size adds weight, envelope and fuel burn; specify the next size up only if the duty cycle really needs the headroom. |
| A non-Cummins engine of similar output | Parts and service for Cummins families are available in most markets, which matters more over ten years than the purchase price on day one. |
