⚙️ Key Features

• Medium duty rating
• Published at 50 kg
• 60 applications across six engine series
• Inlet and Exhaust System group
• L=1370mm (Volvo assembly listing)

🔌 Function

Silences the exhaust pulse as the gas passes through it, cutting the noise the installation puts out.

⚠️ Common Signs of Failure

• Exhaust note getting louder or changing character
• Rattle from broken internal baffles
• Rust streaks, scale or holes in the shell
• Soot or fume traces at the inlet or outlet joints
• Back pressure high enough to cost power

🛠️ Service Notes

• The published figure of exactly 50 kg looks like a rounded value, but this is a large item either way and needs freight handling and two people to fit
• Confirm the medium duty rating suits your installation, as a silencer of the wrong duty will not give the attenuation intended
• Support the muffler properly and check the joints and hangers, since an exhaust leak inside the boat is a fume hazard

📦 Condition

• Genuine Volvo Penta part
