Manufactured to OEM specifications, this neoprene impeller restores proper cooling water flow through the lower unit water pump, protecting the powerhead from overheating damage.\u003c\/p\u003e\u003ch2\u003eParts Desk Insight — Best Use\u003c\/h2\u003e\u003cp\u003eThis impeller is the correct service part for routine water pump maintenance on Johnson\/Evinrude outboards. Best practice is to replace the impeller every 2–3 seasons or 200 hours of operation — whichever comes first — regardless of visible wear. Impeller vanes can harden and lose flexibility before showing obvious damage, leading to reduced cooling flow and potential engine overheating. Always replace during lower unit service or anytime the gearcase is opened.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTip:\u003c\/strong\u003e For a complete water pump service, pair this impeller with a full water pump repair kit that includes the housing, wear plate, gaskets, and seals.
