Use the Sierra Marine 188923 impeller when servicing a compatible water pump or replacing an impeller that has become worn, cracked, hardened, or damaged.

Always inspect the pump housing, cover, key, gasket, and related components during installation, replacing any worn parts as needed.
Before ordering or installing, verify that Sierra Marine part number 188923 matches your engine, water pump assembly, and application requirements. Marine cooling systems can vary by manufacturer and model, so consult the service manual and compare the original component with the replacement. Install the impeller according to the manufacturer's recommended procedure, using the correct lubricant and installation orientation where specified. After service, check for leaks and confirm that the cooling system is operating properly.
