It's the structural enclosure that surrounds and protects the flywheel, provides the mounting interface between the engine block and the starter, and keeps critical rotating components properly aligned and shielded. When it cracks, corrodes through, or takes impact damage, you're looking at a repair that can't wait — a compromised housing puts the flywheel, starter, and surrounding components at risk.\u003c\/p\u003e\n\u003cp\u003eThe #865657A04 is a genuine Mercury OEM Flywheel Housing Assembly, weighing in at over 11 pounds of precision-cast construction. Fit and alignment tolerances on a flywheel housing are tight — this isn't a part where close enough works. The housing has to mate correctly to the block, align the starter drive precisely, and seal out water and debris. Genuine Mercury construction ensures all of that is right the first time, without the fitment headaches that can come with non-OEM alternatives.\u003c\/p\u003e\n\u003cp\u003eIf you're doing a major engine rebuild, replacing a damaged housing after an impact, or sourcing parts for a repower, the #865657A04 is the correct replacement for compatible Mercury applications. \u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eNormalized SKU:\u003c\/b\u003e 865657A04\u003cbr\u003e\u003cb\u003eUPC Code:\u003c\/b\u003e 745061630406\u003c\/p\u003e","brand":"Mercury Marine","offers":[{"title":"Default Title","offer_id":53399439212849,"sku":"MRC-865657A04","price":1095.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0015\/7184\/8291\/files\/mercury-flywheel-housing-assembly-865657a04-745061630406-1230156664.jpg?v=1774866183","url":"https:\/\/www.firstchoicemarine.com\/products\/mercury-flywheel-housing-assembly-865657a04","provider":"First Choice Marine","version":"1.0","type":"link"}
