Sierra 18-3077 Impeller Kit, White - Replaces Jabsco 920-0001, Volvo 875593, 877061

The Sierra 18-3077 Impeller Kit is a white replacement impeller kit built for raw water pumps used in marine engine cooling systems. It is designed as a direct cross-reference replacement for several widely used OEM pump impellers, including Jabsco, Johnson Pump, Oberdorfer, Sherwood Pump, and Volvo units, making it a straightforward swap when an existing impeller has worn out, lost flexibility, or is due for scheduled replacement. The kit ships as a single, complete unit (1 count) ready for installation into a compatible raw water pump housing.

Impellers are wear items that should be inspected and replaced periodically to maintain proper raw water flow and prevent engine overheating. Using a correctly cross-referenced replacement such as the Sierra 18-3077 helps ensure the pump housing seals and rotates as intended. This kit carries the Sierra brand's standard limited warranty.
