Troubleshooting & FAQ

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

A: First, check the Part Number Cross-Reference table to see if our impeller replaces your existing part number. Next, review the Compatible Engine Models list. Finally, compare the dimensions—Diameter: 40mm (1.58"), Width: 19mm (0.75"), Shaft Diameter: 12mm (0.47")—with your old impeller to ensure a match.

Q: What are the signs that my impeller needs replacing?

A: Common signs of a failing impeller include the engine running hotter than normal or overheating, a noticeable reduction in water flow from the exhaust port, and visible damage such as cracks, missing blades, or stiffness in the rubber when inspected.

Q: How often should I replace my water pump impeller?

A: As a general rule, you should inspect your impeller annually and plan to replace it every one to two years, depending on usage. Saltwater environments and high-hour usage may require more frequent replacement. Always follow your engine manufacturer’s service recommendations.
