828064 Muffler | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta silencer for wet exhaust systems, of the late type, for 45 mm hose. It weighs 2.676 kg and is listed for 61 applications across MD, D, MS and AQD series engines. The silencer is made of reinforced rubber with acid resistant stainless steel end pieces, quietens the exhaust with a minimum of back pressure and doubles as an effective water-lock, its large cooling water capacity removing the risk of water siphoning back into the engine when it is stopped. Adjustable mounting brackets make it straightforward to install. Silencer 828837 shares every published dimension with this one but is the horizontal exhaust exit version, so hose size alone will not separate the two.

🚤 Compatibility

• Engine Family: MD, D, MS, AQD

🔌 Function

Damps exhaust noise and acts as a water-lock, holding the gas and water mixture together in the wet exhaust run before it leaves the hull.

⚠️ Common Signs of Failure

• Exhaust note gone louder or harsher
• Water or soot weeping from a seam or spigot
• Casing corroded, blistered or soft at the bottom
• Rattling or loose internals when the unit is shaken
• Back pressure raised, with black smoke or lost revs

🛠️ Service Notes

• Confirm the exhaust exit arrangement - the horizontal exit version is 828837, and both take 45 mm hose and share the same published dimensions
• Renew both hoses and all clips at the same time, and check the silencer sits so it cannot hold standing water
• The acid resistant stainless steel end pieces are chosen for a wet exhaust duty, where the silencer carries seawater as well as exhaust gas
