⚙️ Key Features

• 7.897 kg - a heavy item
• 18 applications across four engine series

• Note carries a production-batch breakpoint

🔌 Function

Turns the exhaust away from the manifold or turbocharger outlet and carries it on to the next section.

⚠️ Common Signs of Failure

• Exhaust fumes or soot inside the engine space
• Blowing noise that changes with load
• Rust scale, deep pitting or a burnt-through wall
• Cracks at the flange or a weld
• Flange face distorted so the joint will not seal

🛠️ Service Notes

• An exhaust leak puts carbon monoxide into the boat - check the joint carefully after fitting and cure any blow at once
• Coolant pipe 842428 replaces the same two old numbers, so confirm which part you need
• At 7.897 kg it is heavy to handle and to ship, and expect seized fasteners
