854760 Muffler | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta silencer for wet exhaust systems for 100 mm hose, with a horizontal exhaust exit suited to installations with limited height - the largest silencer in the range. It weighs 6.146 kg and is listed for 35 applications across the D, TAMD, KAMD and KAD series. The body is reinforced rubber with acid resistant stainless steel end pieces; it quietens the exhaust with a minimum of back pressure and doubles as a water-lock, its large cooling water capacity stopping water siphoning back into the engine once it is shut down. Adjustable mounting brackets make it easy to install.

🚤 Compatibility

• Engine Family: D, TAMD, KAMD, KAD
• HP Range: 145-320 HP

🔌 Function

Silences the wet exhaust and acts as a water-lock, carrying the gas and cooling water out through a horizontal exit.

⚠️ Common Signs of Failure

• Exhaust noise rising sharply compared with how it used to sound
• Water or soot staining at the seams or the hose connections
• Casing corroded, pitted or split
• Exhaust fumes noticeable in the engine space or accommodation
• Internal baffles broken up, heard as a rattle when the unit is rocked

🛠️ Service Notes

• Renew the exhaust hoses and clamps at the connections while the silencer is out
• A leaking wet exhaust puts exhaust gas into the boat, so check the joints and run the engine before closing up the compartment
• Confirm the 100 mm hose size and the horizontal exit against your installation, since both are fixed by this part number
• The acid resistant stainless steel end pieces are chosen for a wet exhaust duty, where the silencer carries seawater as well as exhaust gas
