Installation Notes
- Turn off the engine, allow it to cool, and disconnect the battery before beginning work.

- Remove the old seal carefully without damaging the housing or sealing surfaces.
- Clean and dry the seal seat, removing dirt, corrosion, and old sealant where applicable.
- Compare the new seal with the original before installation and confirm its orientation according to the applicable service instructions.
- Use a suitable seal driver to press the seal evenly into position. Do not strike the sealing lip directly or install the seal at an angle.

- Check for water intrusion and abnormal noise during the post-service inspection before returning the vessel to normal operation.
Troubleshooting and FAQ
How do I confirm that this seal fits my sterndrive?
Confirm that your drive is one of the listed Volvo Penta SX-C, SX-M, SX-R, SX-S, or DP-SM models, or the applicable OMC Cobra configuration. Compare the old seal and its part number with the references on this page. If the drive model, seal dimensions, or part number differs, consult the manufacturer's service information before ordering.
Is this a complete gimbal bearing or sterndrive gasket kit?
No. This listing is for one gimbal bearing oil seal only. It does not include a gimbal bearing, bellows, gasket set, key, hardware, or other sterndrive service components.
When should the seal be replaced?
Replace the seal when it is worn, damaged, leaking, or removed during related gimbal bearing or sterndrive service. Inspect the bearing, bellows, housing, and sealing surfaces at the same time.
Can the seal be damaged during installation?
Yes. An angled installation, damaged sealing lip, contaminated seal seat, or unsuitable driver can cause leakage. Press the seal evenly with an appropriate driver and follow the applicable service instructions.
Is this an OEM Volvo Penta or OMC part?
No. This is an aftermarket replacement seal. Volvo Penta and OMC numbers shown on this page are manufacturer reference numbers for identification and compatibility comparison.
What should I do if my application is not listed?
Do not assume fitment from a similar-looking drive. Compare the original part number and dimensions, then verify the application using the manufacturer's service information or a qualified marine technician.
Safety and Important Information
- Verify the drive model, original part number, seal dimensions, and installation orientation before purchase and installation.
- This product is an aftermarket replacement and is not an OEM component.
- Professional installation is recommended because sterndrive removal and gimbal housing service require specialized procedures and tools.
- Do not treat unrelated gasket-set or kit references as equivalent to this single seal.
