Installation Guide

1. Shut off the seacock and disconnect the battery before beginning work.
2. Remove the raw water pump from the engine.
3. Disassemble the pump housing to access the old shaft seal.
4. Carefully remove the old seal, taking care not to scratch or damage the pump housing.
5. Thoroughly clean the seal bore in the housing, removing any corrosion or debris.
6. CRITICAL: Orient the new seal correctly. The open side with the visible garter spring must face inward towards the impeller. Installing it backward will result in an immediate leak.
7. Gently press the new seal into the housing using a suitable socket or bearing driver that matches the seal's outer diameter. Ensure it goes in straight and is fully seated.
8. Reassemble the pump, install a new impeller and gasket, and mount it back on the engine.

Troubleshooting & FAQ

Q: How do I confirm this seal fits my engine?

A: The most reliable method is to match the part number. This seal replaces Volvo Penta 827247 and Johnson Pump 05-29-105, among others listed in our cross-reference table. You can also verify your engine or pump model is listed in the compatibility tables.

Q: How is this seal installed?

A: Installation orientation is critical. The open side of the seal, where you can see the metal garter spring, must face inward toward the pump's impeller. Installing it in reverse will cause it to leak and fail prematurely.

Q: What are the signs of a failing water pump shaft seal?

A: The most common symptom is water dripping from the weep hole on the bottom of the pump body. This indicates the seal has failed and is allowing water from the impeller side to pass through to the pump bearings.
