Logbook reference values
| Parameter | Expected | Deviation means |
|---|---|---|
| Exhaust gas temperature after cylinder | 355-430 °C at MCR | >20 °C spread |
| Pmax | As per shop test ±3 bar | Spread >5 bar |
| Scavenge air pressure | 2.0-2.6 bar abs | Too low |
Common Failure Modes
Camshaft wear
Symptoms: Timing drift
Causes: Long-term operation
Preventive: Cam profiles at docking.
Fuel pump wear
Symptoms: Spread
Causes: Catfines
Preventive: Fuel quality.
Expert tips
- 💡 S35MC-C: stroke-to-bore ratio 4.0 is standard for S-type — more efficient than L-type
- 💡 MC-C in small bore: spare parts becoming scarcer — plan long-term with the owner
