Sierra Impeller Kit 223-3303 for Kohler Generators, Interchangeable with Kohler 229826

The Sierra 223-3303 Impeller Kit is a replacement water pump impeller built for Kohler marine generators. It is interchangeable with Kohler part number 229826, making it a straightforward swap when the original impeller wears out, loses flexibility, or fails to move sufficient cooling water. The kit includes one gasket per package, so the corresponding sealing surface is covered along with the impeller itself, reducing the chance of a leak after installation. The impeller is white in color and is manufactured to meet or exceed the specifications of the original equipment part it replaces, which is part of Sierra's standard approach to engine and drive components used in the marine environment. This part is designed for use in marine generator cooling systems, where a properly functioning impeller is essential for maintaining adequate raw water flow and preventing overheating. Because impellers are a wear item, keeping a Sierra 223-3303 on hand or replacing on a maintenance schedule helps avoid unexpected generator shutdowns. The kit fits a broad range of Kohler generator models spanning multiple horsepower and configuration variants, and buyers should confirm the model designation and serial number range against their own generator before ordering to ensure correct fitment.
