3862907 Kit | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta exhaust riser 150 mm, quoted as 6 inch, in height, listed against 4.3 to 8.1 litre inboard installations, in the 3.00 inch (76 mm) size. It weighs 27.125 kg, covers 41 applications across the DPX family and supersedes 3862097, catalogued earlier as a kit, so the current supply may differ in what is included. A riser raises the level of the exhaust elbow where the engine sits at or below the waterline and reduces the risk of siphonage back into the engine. Two other risers share the 150 mm height, 40005141 and 40005142, both for SX and DPS installations.

🔌 Function

Raises the exhaust elbow above the waterline and turns the gas flow into the hose, keeping water from running back into the manifold.

⚠️ Common Signs of Failure

• Water in a cylinder or a hydraulic lock on cranking
• Rust-coloured water weeping from the riser joint
• Soot or salt trails at the gasket face
• Casting corroded through internally, so exhaust and cooling water mix
• Engine noise sharper or exhaust note changed as the internal passage breaks down

🛠️ Service Notes

• Height and bore both matter - a 150 mm riser cannot be swapped for a different height without changing the hose run and the waterline clearance
• This is the inboard listing; 40005141 and 40005142 are the 150 mm risers for SX and DPS installations
• At 27.125 kg this is a two-person lift and a freight item, so plan the handling before starting
• Fitted where the engine installation sits at or below the water line
