Several Sherwood impellers share similar diameters and widths, so the spline count and installed pump model are the most reliable identifiers. The most common mix-up is with the 17000K, which looks nearly identical but uses a keyed 5\/8-inch hub — not a spline. Always confirm the hub type before ordering. Sherwood impeller puller 25106 is the correct removal tool for this series and should be on hand before beginning service.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eCompatible \u0026amp; Related Products\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eOther Sherwood impeller kits, pullers and pump accessories available at Marisol Marine:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sherwood-impeller-puller-25106-27000k-series-removal-tool\"\u003eSherwood Impeller Puller 25106 – 27000K Series Removal Tool\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sherwood-29000k-impeller-kit-raw-water-pump\"\u003eSherwood 29000K Impeller Kit – Large Raw Water Pump Service Kit\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sherwood-impeller-kit-18000k-raw-water-pump-service-kit\"\u003eSherwood 18000K Impeller Kit – Raw Water Pump Service Kit\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sherwood-raw-water-pump-neoprene-impeller-kit-12-blade-17000k-shw\"\u003eSherwood 17000K-SHW Raw Water Pump Neoprene Impeller Kit\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sherwood-08000k-impeller-kit\"\u003eSherwood 08000K Impeller Kit\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\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51156142096420,"sku":"762-27000K","price":219.79,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/cf4fdaf9-f8b4-4937-bc6c-86ac87ea3dfe.png?v=1785133177","url":"https:\/\/marisolmarine.com\/products\/sherwood-27000k-impeller-kit-p270-raw-water-pump","provider":"Marisol Marine Company","version":"1.0","type":"link"}
