Confirm the pump model and impeller width carefully, particularly on Sherwood pumps that use both impeller sizes in the same assembly.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eCompatible \u0026amp; Related Products\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sherwood-09959k-impeller-kit\"\u003eSherwood 09959K Impeller Kit – Alternate listing \/ cross-reference\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sherwood-water-pump-cam-alignment-pin-s21566\"\u003eSherwood Water Pump Cam Alignment Pin S21566 – Required for correct cam orientation on reassembly\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sherwood-impeller-puller-25106-27000k-series-removal-tool\"\u003eSherwood Impeller Puller 25106 – Recommended for safe impeller removal\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sherwood-impeller-puller-17000k-p1710-p1715-p1720-p1730-removal-tool\"\u003eSherwood Impeller Puller 17000K Series – Alternative removal tool\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eParts Desk Insight – Best Use\u003c\/h3\u003e\n\u003cp\u003eThe 762-09959K is a complete service kit — the \"K\" suffix confirms it includes all sealing components (gasket + O-ring) alongside the impeller blade. Note that an alternate listing exists in the catalog (09959K without the 762- prefix); verify with your supplier data which part number your customer's pump manufacturer references to avoid duplicate-order confusion. Before installation, inspect the pump housing bore for scoring; a worn bore will shorten impeller life regardless of kit quality. Use an impeller puller for removal to prevent blade tearing and fragment ingestion into the cooling circuit. Confirm cam orientation with alignment pin S21566 before closing the pump cover. Neoprene is the correct material for raw water applications at normal operating temperatures.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51156141965348,"sku":"762-09959K","price":68.19,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/525db185-386b-47e2-9ffa-85b8d492c5ed.png?v=1785134888","url":"https:\/\/marisolmarine.com\/products\/sherwood-762-09959k-impeller-kit","provider":"Marisol Marine Company","version":"1.0","type":"link"}
