Suzuki Water Pump Impeller Key 09420-04006

Suzuki Water Pump Impeller Key 09420-04006 is a genuine Suzuki OEM replacement key used to secure the water pump impeller to the driveshaft on select Suzuki outboards.

Compatible with the following:

• Select Suzuki DF-series four-stroke outboards
• Select Suzuki DT-series two-stroke outboards
• Other Suzuki Marine applications requiring part number 09420-04006

The impeller key fits into the driveshaft and engages the water pump impeller, allowing the impeller to turn with the shaft and circulate cooling water through the engine. A damaged, worn, or missing key can prevent the impeller from operating correctly even when the impeller itself is in good condition.

This small component is commonly inspected or replaced during water pump service. Using the correct OEM key helps ensure proper fit between the driveshaft and impeller.

This product is the impeller key only. The water pump impeller and other cooling-system components are sold separately unless otherwise specified.
