Confirm Volvo Penta part number \u003cstrong\u003e21951342\u003c\/strong\u003e against your engine serial number and the correct raw-water pump diagram before ordering, especially on older engines where pump revisions or cover changes may exist.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eWhen This Part Needs Replacement\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eReplace this impeller kit during scheduled raw-water pump service, or when the existing impeller shows cracked vanes, hardening, missing blades, reduced cooling-water flow, or overheating symptoms. Replacing the gaskets and lubricant at the same time is the cleaner way to restore pump service properly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eMatch the kit to the exact pump and cover style before installation. Current public references support a \u003cstrong\u003eslotted shaft pin drive\u003c\/strong\u003e impeller with a \u003cstrong\u003e6-blade\u003c\/strong\u003e design, so confirming those pump details before disassembly is a useful cross-check. Replacing the gasket(s) during service is recommended since the current kit content trail shows they are included for reassembly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eCurrent parts references show \u003cstrong\u003e3586496\u003c\/strong\u003e as the earlier number replaced by \u003cstrong\u003e21951342\u003c\/strong\u003e.

Checking the exact pump style, lid style, and drive type first usually saves more time than reopening the pump because the replacement looked close but was not quite right.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563990515748,"sku":"21951342","price":71.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/4c726dcd-15c4-4688-8bb0-28c03f8bdb8e.png?v=1773018246","url":"https:\/\/marisolmarine.com\/products\/volvo-255","provider":"Marisol Marine Company","version":"1.0","type":"link"}
