Mercury Exhaust Pipe Assembly (Bullhorn)

The Mercury Marine 8M0067339 Exhaust Pipe Assembly, commonly referred to as a “Bullhorn” exhaust pipe, is a genuine Mercury OEM exhaust system component designed for selected MerCruiser TDI diesel engines. This heavy-duty exhaust connection assembly routes exhaust gases from the engine to the transom exhaust system while maintaining proper exhaust flow and engine performance.

Manufactured to Mercury Marine specifications, the assembly is engineered to withstand high exhaust temperatures, vibration and the harsh marine environment. Genuine Mercury exhaust components provide proper fitment, corrosion resistance and long service life, making them essential for maintaining the reliability of diesel propulsion systems.

A damaged or corroded exhaust pipe can result in exhaust leaks, increased engine noise, reduced performance and potential water intrusion issues. Replacing worn exhaust components helps maintain engine efficiency, safety and compliance with Mercury service requirements.

This assembly is commonly fitted to MerCruiser 3.0L TDI diesel sterndrive and inboard applications and serves as a direct OEM replacement part.
