It measures 3-3\/4 in. across the outside diameter and may also fit other Jacuzzi model pumps.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMeasure before you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eImpellers look alike and the wrong one either will not seat or will not move water. The dimensions are all listed here for that reason: 3-3\/4 in. outside diameter, 15\/32 in. thickness at the outside edge and 9\/32 in. on the inside face, 3-1\/4 in. from the end of the shaft to the front of the intake, an inlet of 2-1\/16 in. outside and 1-13\/16 in. inside, and a shaft cover 1-1\/2 in. long by 5\/8 in. across. Compare those against the impeller in your hand rather than going by pump model alone.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat a worn impeller looks like\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe vanes wear thin, the eye of the impeller opens up, and small debris chips the edges. Flow drops off while the motor still runs at full speed and sounds normal, which is what separates a worn impeller from a clogged one. The shaft cover threads onto the motor shaft, so the impeller comes off with the motor, and the shaft seal should be replaced at the same time.\u003c\/p\u003e","brand":"Jacuzzi Bros.","offers":[{"title":"Default Title","offer_id":48634491699412,"sku":"JAC-101-9510","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_43f3bfef-7f33-4dec-ab48-89b4d601191d.jpg?v=1788832642","url":"https:\/\/www.activepoolsupply.com\/products\/1hp-impeller-3-3-4-diameter","provider":"Active Pool Supply","version":"1.0","type":"link"}
