Installation Notes

1. Disconnect the battery and follow the applicable MerCruiser service procedure before working on the sterndrive.
2. Remove or disassemble the necessary sterndrive components to access the yoke seal.
3. Remove the old seal carefully so the seal bore, shaft, and adjacent components are not damaged.
4. Clean the sealing surfaces and inspect the yoke and bore for wear, corrosion, or scoring.
5. Lubricate or seal the replacement only as specified by the applicable service manual and the seal material requirements.
6. Install the new seal squarely with a suitable seal driver. Do not strike the sealing lip or distort the seal.
7. Reassemble the yoke and sterndrive components using the manufacturer's torque specifications.
8. Refill the sterndrive with the correct lubricant and check for leaks after assembly and initial operation.

Professional installation is recommended because access to the yoke seal may require sterndrive removal and specialized service procedures.

Troubleshooting & FAQ

What does this seal fit?

The available catalog evidence identifies it as a Bravo yoke oil seal associated with OEM reference 26-807006. Verify the drive identification and original seal before ordering.

Is this a complete U-joint or yoke assembly?

No. This listing is for one replacement oil seal only. It does not include the U-joint, yoke, bearings, key, gaskets, lubricant, or installation tools.

Is this an OEM MerCruiser part?

No. This is an aftermarket replacement. OEM reference 26-807006 is provided for application and cross-reference purposes.

Does reference 86730 identify the same part?

The available GLM catalog identifies 86730 as a Bravo yoke oil seal associated with OEM reference 26-807006. Confirm the number against your original part and service documentation.

Does this listing confirm Blackhawk fitment?

No specific Blackhawk fitment range was established in the available catalog evidence for this product. Do not rely on a Blackhawk model description without verifying the original seal number and drive documentation.

How can I tell whether the seal needs replacement?

Common indications include lubricant leakage around the yoke area, recurring low lubricant levels, or visible wear or damage to the old seal. Inspect the yoke and sealing surfaces as part of the repair.

Can I install this seal without removing the sterndrive?

Access depends on the exact drive and service procedure. Yoke-seal replacement commonly requires removal or substantial disassembly of sterndrive components. Follow the appropriate service manual.

What lubricant or sealant should be used?

Use only the lubricant, sealant, and installation method specified by the applicable service manual. Using an incompatible product can damage the seal or compromise sealing performance.

How often should the seal be replaced?

Replace it when leakage, damage, or wear is found, or during a rebuild when the service procedure calls for seal replacement. A universal operating-hour replacement interval is not specified for this product.
