Product Details

The Sierra 18-3025 is a replacement impeller key designed for use in the water pump cooling systems of Honda outboard motors. This small but critical component locks the impeller to the pump shaft, ensuring proper rotational alignment and reliable water flow to keep your engine running at safe operating temperatures.

Manufactured by Sierra International — a trusted name in marine engine parts — this impeller key is a direct replacement for Honda OEM part number 90752-ZW9-A30. It is commonly included as part of water pump repair and service kits for a range of Honda outboard applications.

Key Features:

  • Direct replacement for Honda OEM part 90752-ZW9-A30
  • Manufactured to meet or exceed original equipment specifications
  • Essential component for water pump impeller service and rebuild
  • Sold individually; often used alongside impeller 18-3100 and related water pump kit components
  • Compatible with various Honda outboard motor applications

When servicing your outboard's water pump impeller, replacing the impeller key at the same time is considered best practice to ensure a complete, reliable repair. Sierra's marine-grade construction provides confidence in both performance and longevity.

Easy ordering process, and the best price.

They had the color I wanted. I'll review once I get my order

Good price, fast shipping

So far so good

Found the best price and was pleasantly surprised by the speed of shipping. No tracking info up front, but customer service was able to provide and was very friendly. Buy with confidence and don't look back!

Good so far
