Installation Guide

1. Disconnect the battery and remove the stern drive unit from the transom assembly following your service manual. Support the drive securely on a clean workbench.
2. Drain all gear oil from the lower unit and remove the propeller shafts. Clean all old sealing surfaces thoroughly with a degreaser and inspect for wear or corrosion.
3. Carefully remove the old seals from the lower gear housing using a seal puller or appropriate tool. Avoid scratching or damaging the seal bores.
4. Clean the seal cavities completely and inspect for any nicks, burrs, or damage that could compromise the new seals.
5. Lubricate the new seals lightly with gear oil or marine-grade grease. Install each seal squarely into its bore using a seal driver or appropriately sized socket.
6. Reinstall the propeller shafts, ensuring all bearings and components are properly seated. Torque all fasteners to manufacturer specifications.
7. Refill the lower unit with the correct type and quantity of gear oil. Check for leaks by running the unit briefly and inspecting all seal areas.
8. Reinstall the stern drive unit to the transom, reconnect all linkages and cables, and perform a final inspection before returning to service.

Troubleshooting & FAQ

Q: How do I confirm this seal kit fits my Volvo Penta stern drive?
A: Cross-reference your original part number (Volvo 876267, REC 22087, or GLM 87840) with our compatibility table. Verify your stern drive model matches the DP or DPX series listed above.

Q: How often should I replace the lower gear housing seals?
A: Replace seals whenever you notice gear oil leaks, water intrusion in the oil, or during major lower unit service (typically every 3–5 years or as recommended by your service manual).

Q: What are the signs that my lower unit seals are failing?
A: Common symptoms include milky or contaminated gear oil, visible oil leaks around the prop shafts, decreased drive performance, or unusual noise from the lower unit during operation.
