Troubleshooting & FAQ
How do I know if this gasket will fit my specific Volvo Penta model?
This gasket fits a wide range of DPS, FWD, SX, and TSK series sterndrives and saildrives. Please consult the "Engine & Model Compatibility" table and cross-reference your model number. Always verify by comparing to your old part before installation.
Do I need to use sealant with this rubber gasket?
This gasket is designed to create a seal on its own in most applications. However, we strongly recommend consulting your engine’s official service manual for the specified procedure, as some models may require an additional sealant.

Common signs include water leaks into the boat's bilge, oil or fluid leaks from the drive unit, or visible signs of cracking, brittleness, or degradation of the old gasket material.
