# 3854286 Impeller | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta raw water pump impeller for the Sherwood pump, weighing 0.086 kg and listed for 24 applications. It supersedes part number 835512. The accessories catalogue prints it as the impeller for the MD-code builds of the 7.4GL and for the 8.2GL, while the HU, NC and LK builds of the 7.4GL take impeller kit 21951346 instead - the build code in the engine designation is what decides. The same number is listed again as the impeller kit for the AQ225B, AQ225C and AQ255A.
