Troubleshooting & FAQ

Q: How do I confirm this gasket fits my Volvo Penta sterndrive?
A: Verify your sterndrive model (SX-A, SX-B, DPS-A, DPS-B, DP-H, DPH, or DPR) and cross-reference the OEM part number 3889788 with your service manual or parts diagram to ensure correct fitment.

Q: When should I replace the pivot housing mounting gasket?
A: Replace this gasket any time the sterndrive is removed for service, repair, or maintenance. It should also be replaced if you notice water intrusion, corrosion around the mounting area, or during routine sterndrive rebuilds.

Q: What are signs that my pivot housing gasket is failing?
A: Common symptoms include water leaking into the sterndrive housing, visible corrosion around the pivot housing bolts, loss of sterndrive fluid, or unusual noises during steering operation.
