At this price point, 342731 is likely a major gasket set, head gasket, or multi-component gasket assembly rather than a single small gasket. Confirm the exact application, assembly, and engine serial number using the applicable Mercury parts diagram before ordering.\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.\u003c\/p\u003e\n\n\u003ch3\u003eSerial Number Notice\u003c\/h3\u003e\n\u003cp\u003eMercury gasket specifications vary by engine family, displacement, model year, and serial range. Always confirm 342731 against the exact diagram position and engine serial number before ordering.

Given the price point, confirm the full scope of the service before ordering — this is the type of part where ordering the wrong gasket set results in a significant return and reorder delay.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon issues:\u003c\/strong\u003e The most common mistake with higher-value gasket assemblies is ordering by engine family or displacement without confirming the exact serial number. Mercury used different gasket configurations across closely related engine variants, and a gasket set that fits one production range may not fit another. Always verify against the engine serial number and Mercury parts diagram before placing the order.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":51324679094308,"sku":"342731","price":166.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/images_555376fd-c554-464d-b6af-3a1d9639e6f5.jpg?v=1788743366","url":"https:\/\/marisolmarine.com\/products\/merc-37","provider":"Marisol Marine Company","version":"1.0","type":"link"}
