Use pliers or an impeller puller to carefully remove the old impeller. Note the direction of the blades.
Clean the inside of the pump housing, ensuring no old blade fragments remain.
Inspect the end plate and housing for wear or scoring. Replace if necessary.
Lightly lubricate the new impeller and the inside of the pump housing with a suitable marine lubricant.
Install the new impeller, bending the blades in the same direction as the old one (opposite the direction of pump rotation).
Install the new gasket and/or O-ring.
Reinstall the cover plate and tighten the screws evenly.
Open the raw water seacock and start the engine. Check immediately for leaks and proper water flow.

Troubleshooting & FAQ

How do I know if this impeller fits my pump?

The best way to confirm fitment is by matching your existing impeller's part number to the ones listed in our Part Number Matrix. You can also check the compatible pump models listed in the compatibility tables. Always verify dimensions if you are unsure.

What are the signs of a failing impeller?

Common symptoms include engine overheating at idle or low speeds, a reduced stream of water from the exhaust outlet, and visible cracks or missing blades on the impeller itself during inspection. Regular inspection is key to preventing engine damage.

How often should I replace my water pump impeller?

As a general rule, impellers should be inspected annually and replaced every one to two years, depending on usage (hours run) and water conditions (sandy or silty water causes faster wear). Always consult your engine's service manual for specific recommendations.

Can I run the engine without water after installing this impeller?

No. Never run a raw water pump dry, even for a few seconds. The water acts as a lubricant for the neoprene impeller. Running it dry will cause immediate damage to the impeller blades.

The included gasket doesn't seem to fit. What should I do?

This kit is designed for a range of pumps, so it may include common gaskets or O-rings. If the included gasket does not match your specific pump model, you may need to reuse your old gasket if it is in good condition or source the correct one separately.

Is this part the same as the original OEM one?

This is an aftermarket component designed to meet or exceed OEM specifications for fit, material, and performance. It offers a reliable, cost-effective alternative to the original manufacturer's part.

What is the difference between OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.

What are the shipping speed & cost?

We ship worldwide quickly—typical transit 5–15 days. Standard shipping is free; expedited options appear at checkout where available.

What is the warranty & return policy?

Covered by a 1-year warranty against manufacturing defects under normal use. If issues arise, contact support with your order details. Returns are accepted within our standard window (unused & in original condition). See our policy page or reach out for instructions.
