The @8 notation in Mercury parts catalogs indicates that 8 seals are required at this position within the assembly. Confirm the exact engine model, serial number, and diagram position before ordering to ensure the correct seal specification and quantity for your application.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cp\u003eConfirm your engine model, serial number, and the applicable Mercury parts diagram before ordering.

Because the catalog position calls for 8 seals, always order the full quantity required for the assembly — partial replacement of a seal set in a high-heat or high-pressure application is not recommended.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon issues:\u003c\/strong\u003e The most common mistake with catalog seals like 34217 is ordering the wrong quantity. The @8 notation means the full assembly requires 8 of this seal — ordering only 1 or 2 creates a situation where the job cannot be completed correctly. Confirm the total quantity needed from the diagram before ordering. Also confirm the diagram position carefully — visually similar seals at adjacent positions in the same assembly are often different part numbers.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":51324678701092,"sku":"34217","price":9.44,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/d532722d-8f10-4bf9-817c-fdca21cb8c16.png?v=1788742762","url":"https:\/\/marisolmarine.com\/products\/merc-27","provider":"Marisol Marine Company","version":"1.0","type":"link"}
