🔌 Function

The turbocharger converts exhaust energy into compressor rotation, forcing additional air through the intercooler and into the engine. This allows the compact Yanmar 4JH engine to produce substantially more power than a naturally aspirated engine of similar displacement.

Common signs of failure:

• Reduced boost and loss of engine power

• Engine cannot achieve its rated operating speed

• Excessive black smoke during acceleration

• Blue smoke or increased engine-oil consumption

• Whining, siren, scraping or grinding noises

• Oil inside the compressor outlet or intake hose

• Excessive radial or axial shaft movement

• Compressor or turbine wheel damage

📦 Condition

• Sawley's Select Marine Parts aftermarket replacement

• Brand new

• Supplied in original or equivalent packaging
