The \u003cstrong\u003eA2\u003c\/strong\u003e suffix designates a revised assembly version — this is the current production specification and supersedes earlier revisions. At this price point, this is a precision washer assembly (such as a thrust washer stack, sealing washer assembly, or bearing-interface washer set) rather than a simple flat washer.

The A2 revision designation means this is the updated production part — it is the correct replacement regardless of which earlier revision was originally installed.

Also confirm the diagram position: Mercury uses several washer assemblies across different engine and drive locations that share similar part number formats but are not interchangeable.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eRelated Parts\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/mercury-mercruiser-quicksilver-thrust-washer-805100\"\u003eMercury MerCruiser Quicksilver Thrust Washer 805100\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/mercury-mercruiser-quicksilver-thrust-washer-kit-835467q01\"\u003eMercury MerCruiser Quicksilver Thrust Washer Kit 835467Q01\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/mercury-thrust-washer-18448\"\u003eMercury Thrust Washer 18448\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/mercury-quicksilver-washer-20583\"\u003eMercury Quicksilver Washer 20583\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/mercruiser-washer-20084-pack-of-5\"\u003eMerCruiser Washer 20084 – Pack of 5\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/mercury-mercruiser-propeller-shaft-toothed-lockwasher-13-423511\"\u003eMercury MerCruiser Propeller Shaft Toothed Lockwasher 13-423511\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563862589476,"sku":"55073A2","price":128.24,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/ca6d5f0a-e95d-4bd7-a6e6-ac1938f19229.png?v=1787266763","url":"https:\/\/marisolmarine.com\/products\/mercury-mercruiser-washer-assembly-12-55073a2","provider":"Marisol Marine Company","version":"1.0","type":"link"}
