What This Engine Is Built For
Cummins 6BTA5.9-GM100: a 6-cylinder in-line marine diesel engine displacing 5.9 L on a 102 * 120 mm bore and stroke, supplied complete by MEP Power. It is rated at 100 kW (134 HP). The engine is turbocharged & water-air intercooled and water cooled, with a BYC A Pump/GAC Governor fuel system. It is built at the Dongfeng Cummins Plant 6BTA5.9-GM100 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 426 Kg and the overall envelope is 867mm*544mm*988mm.
Key Benefits
- Delivers 100 kW (134 HP) from 5.9 L as a factory-rated assembly.
- Turbocharged & Water-air Intercooled induction with water cooling 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 426 Kg and envelope 867mm*544mm*988mm are published so the installation can be checked before ordering.
- Published fuel consumption of ≤ 240 g/kW.hr 6BTA5.9-GM100 makes running cost predictable.
- Starts without auxiliary aids down to -12℃.
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 6BTA5.9-GM100 variant from a serial number takes experience; MEP Power checks the configuration before quoting.

- Check the gearbox reduction ratio and propeller match before ordering
- Confirm raw-water or keel cooling to suit the hull

- 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 100 kW (134 HP) on paper, but its running history is unknown and the warranty rarely covers the whole engine. |
| A larger engine in the same 6BTA5.9 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. |
