Engine Compatibility
Confirmed public catalog references tie Volvo Penta 3888819 to TSK A-32-NPT / marine propulsion applications, and other catalog references describe it within Volvo Penta exhaust block-off kit diagrams. Because Volvo Penta fitment can vary by drive, transom shield, and serial range, this part should be matched by the exact engine or drive model before ordering.
Serial Number Fitment Notice
Please verify fitment by your Volvo Penta engine, drive, or transom shield serial number before purchase. Volvo Penta parts catalogs can assign similar exhaust service parts across different assemblies, so serial-number confirmation is the safest way to ensure the correct match.
When This Part Needs Replacement
This exhaust block-off is typically replaced when:
- servicing or converting an exhaust-related assembly that requires a block-off component
- the existing block-off plate or kit component is damaged, corroded, or no longer sealing correctly
- related gasketed exhaust service work calls for renewing the block-off hardware and sealing parts
These use cases are inferred from how Volvo Penta catalogs the part within an exhaust block-off assembly and related service diagram.
Installation Notes
- Confirm the correct application by serial number before installation
- Inspect the related gasket and fastening hardware during service
- Where applicable, replace associated sealing and locking hardware at the same time for a clean, reliable repair
