How to fix: replace the faulty impeller with a new one, ensuring that it’s the correct model for your engine. replace the gasket and woodruff key if necessary. reassemble the lower unit or gearcase, restart the engine, and check for water flow from the telltale. if the issue persists, continue to the next possible cause.
