This exhaust flap/check valve for Volvo Penta drives is a 70 mm spare part for the sterndrive exhaust system. The variant is compatible with Volvo Penta DP-D, DP-D1, and DP-E.
The flap valve functions as a one-way valve in the exhaust system. It limits the backflow of water through the sterndrive, among other things during rapid deceleration.
The part has OEM cross-reference Volvo Penta 872438. Volvo Penta is a compatibility and OEM reference; the product is not identified as an original Volvo Penta part.
A mounting plate with OEM no. 872439 and four blind rivets with OEM no. 977711 are installation-related parts for the OEM assembly. These are separate components and are not indicated as included.
