Troubleshooting & FAQ

How do I know if this gasket will fit my engine?

This gasket is listed as a direct replacement for Volvo Penta part number 981183 and fits models such as the KAD44P-B. The best way to ensure fitment is to verify your original part number against our cross-reference list and compare our product photos with your part.

Do I need to use sealant with this gasket?

Typically, this gasket is designed for a dry installation. However, we strongly recommend consulting your engine's official service manual for the manufacturer's specific guidelines on using sealants for your model.

Common symptoms of a bad gasket include visible fuel leaks, a strong fuel odor near the engine, reduced engine performance, hesitation during acceleration, or stalling caused by a loss of fuel pressure.

How often should this gasket be replaced?

We recommend replacing this gasket whenever the component it seals is removed for service or inspection. While there's no fixed replacement interval, it should be checked periodically for signs of hardening, brittleness, or leaks.
