Installation Guide

1. Turn off the engine and close the raw water intake seacock.
2. Loosen the screws and remove the cover plate from the sea water pump.
3. Use needle-nose pliers or an impeller puller tool to carefully remove the old impeller from the pump housing.
4. Clean any debris or old gasket material from the pump housing interior and the cover plate sealing surface.
5. Apply a light coat of the included glycerin lubricant to the inside of the pump housing and to the blades of the new impeller.
6. Install the new impeller into the housing. Bend the blades in the same direction as the pump's normal rotation while aligning the keyway or spline.
7. Place the new gasket onto the pump housing, ensuring it is properly aligned with the screw holes.
8. Reinstall the cover plate and tighten the screws in an alternating pattern to ensure an even seal. Do not overtighten.
9. Open the seacock.
10. Start the engine and immediately verify that water is flowing from the exhaust outlet. Check for any leaks around the pump cover.

Troubleshooting & FAQ

Q: How can I confirm this impeller fits my specific engine?
A: The best way is to match your existing part number to our cross-reference list. You can also check the compatible engine models table, but always verify dimensions if you are unsure. When in doubt, checking your engine's service manual is recommended.

Q: My old impeller has 9 blades, but this one has 12. Will it work?
A: This 12-blade impeller is the current design standard specified by the OEM for Jabsco 17935-0001. It replaces older 9-blade versions and is designed to provide equivalent or improved water flow performance in the same applications.

Q: What are the signs of a failing impeller?
A: Common signs include the engine running hotter than normal, a noticeable reduction in water flow from the exhaust outlet, and visible cracks or missing blades on the impeller itself upon inspection.

Q: How often should I replace the engine's raw water impeller?
A: For preventative maintenance, it is recommended to inspect your impeller annually and replace it every 1-2 years, depending on usage hours and operating conditions (e.g., sandy or silty water). Always follow the replacement interval specified in your engine's maintenance manual.

Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
