Always order by the diagram part number first — this is especially important on repowered boats or assemblies that may have been updated under a superseded number. If your diagram shows 32068 or 25-32068, this is the correct part.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563851546660,"sku":"32068","price":14.54,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/23a8f7f0-159f-4203-9199-bfc648257990.png?v=1786482425","url":"https:\/\/marisolmarine.com\/products\/mercury-mercruiser-quicksilver-o-ring-25-32068","provider":"Marisol Marine Company","version":"1.0","type":"link"}
