828837 Muffler | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta silencer for wet exhaust systems for 45 mm hose, with a horizontal exhaust exit suited to installations with limited height. It weighs 2.449 kg and is listed for 45 applications across D, MS and MD series engines. It is made of reinforced rubber with acid resistant stainless steel end pieces, silences the exhaust with minimal back pressure and works as a water-lock, its large cooling water capacity preventing water siphoning back into the engine when stopped. Every published dimension matches silencer 828064, so the horizontal exit is the only thing separating them.

🚤 Compatibility

• Engine Family: D, MS, MD

🔌 Function

Silences the exhaust and acts as a water-lock, keeping gas and cooling water flowing together to a horizontal outlet.

⚠️ Common Signs of Failure

• Exhaust note louder or harder than it used to be
• Water or soot weeping at a seam or spigot
• Casing blistered, corroded or soft at the low point
• Loose internals heard when the unit is moved
• Raised back pressure, with smoke and lost revs

🛠️ Service Notes

• Check the exit orientation before ordering - the late type with the same 45 mm hose size and the same published dimensions is 828064
• Renew hoses and clips together and mount the silencer so it cannot hold standing water
• Any wet exhaust leak inboard is a carbon monoxide risk and should be dealt with straight away
• The acid resistant stainless steel end pieces are chosen for a wet exhaust duty, where the silencer carries seawater as well as exhaust gas
