This is the OEM exhaust block-off for selected Volvo Penta transom-shield exhaust assemblies. It appears in Volvo Penta parts diagrams as part of the exhaust block-off kit, alongside the block-off plate, gasket, and fastening hardware. It is a serial-number-verified service component — fitment should be confirmed against the exact drive and transom-shield model, not by visual match alone.

Serial Number & Drive Fitment Notice

Parts Desk Insights
Best use: Order 3888819 when your transom-shield exhaust diagram or serial-number lookup confirms this part for the block-off assembly being serviced. It is most commonly needed during exhaust block-off kit service or exhaust system conversion work on TSK-series transom shields.
Common customer issue: Exhaust block-off components are easy to mis-order because multiple parts cover similar positions across different drive and transom-shield configurations. Matching by OEM part number and serial number — rather than by appearance or general application — is the most reliable way to ensure the correct block-off, gasket, and hardware combination for your specific assembly.
