Common issues

  • Turbocharger blade erosion due to saltwater or dust ingestion
  • Compressor wheel fouling from oil or carbon deposits
  • Bearing failure from inadequate lubrication or overheating
  • Turbocharger rotor imbalance causing vibration
  • Wastegate actuator malfunction leading to boost pressure issues
  • Oil leakage from turbocharger seals or gaskets

Inspection checklist

  • Visual inspection of turbocharger and components for signs of wear or damage
  • Check compressor and turbine wheel for fouling or erosion
  • Verify proper oil flow and pressure to turbocharger bearings
  • Inspect wastegate actuator and linkage for proper operation
  • Check turbocharger mounting bolts and brackets for security
  • Verify boost pressure and turbocharger performance
  • Inspect air filter and intake system for restrictions
  • Check exhaust system for leaks or restrictions

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
