🔌 Function

  

The turbocharger uses exhaust-gas energy to drive a turbine and compressor assembly. The compressor supplies pressurised air to the intercooler and intake manifold, allowing the engine to burn additional fuel efficiently and produce its rated power.

  

Common signs of failure:

  

• Reduced boost pressure and loss of engine power

• Excessive black smoke under acceleration or load

• Blue exhaust smoke or increased engine-oil consumption

• High-pitched siren, scraping or grinding noise

• Excessive shaft movement or compressor-wheel contact

• Engine oil leaking into the compressor or turbine housing

• Slow acceleration or inability to reach rated engine speed

  

📦 Condition

  

• Sawley's Select Marine Parts aftermarket replacement

• Brand new

• Supplied in original or equivalent packaging
