Installation Guide

Proper installation is critical to prevent premature failure and ensure a watertight seal. Professional installation is recommended.

1. Remove the seawater pump from the engine and take off the pump cover.
2. Remove the impeller, noting its orientation for reinstallation.
3. Carefully remove the old lip seal from the pump housing, avoiding scratching the housing surface.
4. Clean the seal seating area inside the pump housing thoroughly.
5. Lubricate the outer diameter of the new seal with a suitable marine lubricant.
6. Press the new seal evenly into the pump housing until it is fully seated.
7. CRITICAL: Ensure the open side of the seal with the visible garter spring is facing inward toward the impeller. Installing it backwards will cause immediate failure.
8. Reinstall the impeller, cover plate, and gasket, then remount the pump to the engine.

Troubleshooting & FAQ

Q: How do I confirm this lip seal fits my engine?
A: The best way to ensure compatibility is to match your existing part number to our cross-reference list. Please check the "Compatible Engine Models" and "Part Number Cross-Reference" sections. Comparing the dimensions (16mm ID x 28mm OD x 7mm Width) to your old seal is also a reliable verification method.

Q: What are the signs that my water pump seal is failing?
A: Common signs of a failing lip seal include water leaking from the pump's weep hole, an overheating engine at idle or low speeds, or a noticeable drop in water pressure from the exhaust. Rust or corrosion around the pump body can also indicate a leak.

Q: What is the correct way to install this lip seal?
A: The seal must be press-fitted into the pump housing with the open side (where you can see the metal garter spring) facing inward towards the impeller chamber. Incorrect orientation will lead to an improper seal and immediate leaks.

Q: How often should I replace my water pump seal?
A: It is highly recommended to replace the lip seals whenever you replace the water pump impeller. Seals are wear-and-tear items that can degrade over time, and replacing them during impeller service is cost-effective preventative maintenance.
