838327 Muffler | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta silencer for wet exhaust systems for 57 mm hose, listed for the 2003T and 2003TB. It weighs 3.583 kg, covers 47 applications across the D, TMD, MS, TAMD and MD series and supersedes 828065, catalogued earlier as a muffler. The silencer is built from reinforced rubber with acid resistant stainless steel end pieces, quietens the exhaust with a minimum of back pressure and doubles as a water-lock whose cooling water capacity stops water siphoning back into the engine when it is stopped. Adjustable mounting brackets make it easy to install.

🔌 Function

Damps exhaust noise in a wet exhaust system and acts as a water-lock, carrying the gas and cooling water together through its chambers to the outlet.

⚠️ Common Signs of Failure

• Exhaust noticeably louder or with a changed note
• Sooty water traces or drips from the silencer body
• Water or exhaust leaking at the hose connections
• Body corroded through or the internal baffles rattling
• Exhaust fumes detectable in the engine space

🛠️ Service Notes

• Order on the 57 mm hose size and the engine designation - the silencer range is sized 45, 57, 89 and 100 mm
• A leaking wet exhaust can put exhaust gas into the engine space, so treat any fume smell as urgent
• Renew the exhaust hoses and double-clamp the joints when the silencer is changed
• The acid resistant stainless steel end pieces are chosen for a wet exhaust duty, where the silencer carries seawater as well as exhaust gas
