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.
