Several Sherwood impellers share the same 3-3\/4-inch diameter, so confirming both the width and spline count is essential before ordering. The 18000K (14-tooth spline) and 26000K (10-tooth, 3-1\/8-inch wide) are the most common mix-up candidates — measure the old impeller or pull the pump model number before placing the order.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eCompatible \u0026amp; Related Products\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eOther Sherwood impeller kits and pump accessories available at Marisol Marine:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sherwood-18000k-impeller-kit-with-gasket\"\u003eSherwood 18000K Impeller Kit with Gasket\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sherwood-impeller-kit-27000k-raw-water-pump-service-kit\"\u003eSherwood 27000K 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-15000k-impeller-kit\"\u003eSherwood 15000K 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":51156142129188,"sku":"762-29000K","price":498.89,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/shopping_110e9764-b351-4458-b314-8dc9acb446c9.webp?v=1785129517","url":"https:\/\/marisolmarine.com\/products\/sherwood-29000k-impeller-kit-raw-water-pump","provider":"Marisol Marine Company","version":"1.0","type":"link"}
