Installation Guide

  1. Safely secure the vessel and gain access to the stern drive's gimbal housing.
  2. Carefully remove any components obstructing access to the gimbal bearing area.
  3. Use a dedicated seal puller to extract the old oil seal, taking care not to damage the housing bore.
  4. Thoroughly clean the seal bore and inspect it for any deep scratches or gauges.
  5. Apply a thin layer of appropriate marine sealant to the outer metal surface of the new seal.
  6. Using a suitable seal driver or arbor press, press the new seal into the housing until it is fully and evenly seated.
  7. Reinstall the gimbal bearing and any other components that were removed.

Troubleshooting & FAQ

Q: How do I know if this oil seal will fit my drive?

A: This seal is designed for specific Volvo Penta and OMC Cobra drives. Please check the 'Compatible Engine Models' and 'Part Number Cross-Reference' tables on this page. Verifying your drive model and original part number is the best way to ensure a match.

Q: What are the signs of a failing gimbal bearing oil seal?

A: Common signs include water in your gimbal bearing grease, a grinding or roaring noise from the transom area (indicating a failed bearing due to water intrusion), or visible oil/grease leaking from the gimbal housing.

Q: How often should the gimbal bearing oil seal be replaced?

A: It is recommended to inspect the seal whenever you service the gimbal bearing or bellows. As a best practice, replace the seal every time you replace the gimbal bearing to prevent premature failure of the new bearing.
