Johnson Pump Impeller 09-808B-1

Description

The Johnson Pump Impeller 09-808B-1 is a flexible rubber impeller designed for use in raw water cooling pumps, where reliable water flow is essential for engine and generator cooling.

This impeller is commonly fitted to Johnson Pump F35 series raw water pumps and is also used as a replacement in many equivalent pump applications across a range of marine engines and generator sets. Regular replacement helps maintain correct cooling water flow and reduces the risk of overheating caused by worn or damaged impeller vanes.

As impeller specifications can vary by pump model rather than engine brand alone, it is important to confirm compatibility using the pump reference, existing impeller code or dimensions before installation.
