It's a popular pre-season stocking item — straightforward fitment when the OEM number is confirmed.\u003c\/p\u003e\n\u003cp\u003eThe most common ordering mistake is confusing the 09-808B-1 (0.75 in. wide) with the 09-806B-1 (0.50 in. wide) — both are called F35, but the width difference causes poor pump performance if the wrong one is installed. Always cross-check the full impeller or pump number, not just the pump family name. If impeller blade fragments are found when removing the old impeller, trace them through the full cooling circuit before closing up — missed pieces are a frequent cause of recurring overheating.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51156139114532,"sku":"50-17788","price":51.83,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/50-17788_Main.jpg?v=1784926810","url":"https:\/\/marisolmarine.com\/products\/seachoice-f35-impeller-kit-17788","provider":"Marisol Marine Company","version":"1.0","type":"link"}
