Retaining rings should always be replaced — not reused — after removal from a shaft or bore, as the removal process can compromise their holding force.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eUse the correct internal or external snap ring pliers for the ring type and groove orientation. Confirm the ring seats fully and flush in its groove before reassembly. Follow the Mercury service manual for the specific assembly sequence and any adjacent components that should be inspected or replaced at the same time.\u003c\/p\u003e\n\n\u003ch2\u003eRelated Products\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/marisolmarine.com\/products\/merc-175\"\u003eMercury MerCruiser Bearing Carrier Retaining Ring 35128\u003c\/a\u003e — Retaining ring for Mercury \/ MerCruiser bearing carrier assemblies\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/marisolmarine.com\/products\/merc-553\"\u003eMercury MerCruiser Quicksilver Ring Retaining 805272\u003c\/a\u003e — Additional OEM retaining ring for Mercury \/ MerCruiser applications\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/marisolmarine.com\/products\/merc-935\"\u003eMercury E-Ring 87843\u003c\/a\u003e — OEM E-clip \/ E-ring for Mercury assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eBest use case:\u003c\/strong\u003e This retaining ring is the right choice when the Mercury or MerCruiser parts diagram calls out \u003cstrong\u003e53-27290\u003c\/strong\u003e specifically. Retaining rings are sized to very tight tolerances — a ring that is even slightly too large or too small will not seat correctly and can fail under load. Always order by the exact diagram part number rather than trying to match by eye or caliper measurement alone, and plan to replace the ring any time the assembly is disassembled, since reusing a removed ring is not recommended.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563841814564,"sku":"27290","price":1.82,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/d19bda30-fddb-4bb3-be33-b1b205dbf4cf.png?v=1786482263","url":"https:\/\/marisolmarine.com\/products\/merc-93","provider":"Marisol Marine Company","version":"1.0","type":"link"}
