7 = number of cylinders, G = Ultra-Long-Stroke, 60 = bore 600 mm, ME = electronically controlled, C = Compact, 9.6 = Engine Mark.

Background

The 7G60ME-C9.6 is one of the most common configurations for medium to large merchant ships. 7 cylinders, 600 mm bore, 2790 mm stroke — optimum balance of power, smooth running and efficiency. Mark 9.6 as the latest version.

Inspector checklist

Fuel system
  • 7 injectors: Cat Fines, check evenly
  • Fuel booster: pressure, filter
  • Preheater: HFO/VLSFO
  • ME timing: EICU 7-cyl 9.6
Running gear & tribology
  • Ratio 4.65: guide shoes all 7 — main priority
  • Liners: wear, cold corrosion
  • Cylinder oil: Alpha Lubricator Mark 9.6
Control & hydraulics
  • 7 HCUs: 200-300 bar evenly
  • EICU 9.6: diagnostics
  • Hydraulic oil: cleanliness
Exhaust system
  • TC (2x): cleaning, bearings
  • Exhaust boiler
  • Scavenge air receiver: longer receiver with 7 cyl — drainage on both sides
Seals
  • 7 stuffing boxes at ratio 4.65
  • Exhaust valves
  • Scavenge air flaps

Logbook reference values

Parameter Expected Deviation means
Exhaust gas temperature per cylinder 320-390 °C >25 °C across 7 cyl → check injection
P-max ±5 bar Timing
Scavenge air pressure 2.5-3.5 bar TC
Cylinder oil feed rate 0.7-1.1 g/kWh Fuel-dependent
Guide shoe temperature 45-60 °C >65 °C → lubrication

Common Failure Modes

Guide shoe wear
Symptoms: Knocking, temperature
Causes: Ratio 4.65 + 600 mm
Preventive: Clearance every 8000 running hours, all 7
Cat Fine damage
Symptoms: Liner wear
Causes: Cat Fines
Preventive: Separator; fuel analysis
Cylinder balance, 7 cyl
Symptoms: Temperature spread
Causes: Uneven injector wear
Preventive: Replace in sets

Expert tips

  • 💡 7G60 Mark 9.6: best-seller with extensive fleet experience. EICU diagnostics offer PMI and CoCoS data — use for proactive maintenance.
  • 💡 7 cylinders at ratio 4.65: guide shoes are the main inspection point besides Cat Fine management.
  • 💡 Scavenge air receiver at 7 cylinders: longer than at 6 cyl — condensate collects at the ends.
