{"product_id":"emp-water-pump-cup-46-00042","title":"EMP Water Pump Cup Mercury 48752T #46-00042","description":"\u003ch2\u003eEMP 46-00042 Water Pump Cups\u003c\/h2\u003e\n\u003cp\u003eThe water pump cup is a component inside the water pump assembly that works alongside the impeller to direct and maintain coolant flow through the engine. It forms part of the inner chamber that the impeller spins within, and its condition directly affects how efficiently the pump moves water. A cup that is worn, cracked, or distorted reduces the impeller's ability to generate adequate flow even if the impeller itself is in good shape. On a V6 outboard in the 135 to 200 horsepower range, where the cooling demand is significant, a degraded pump cup is the kind of detail that can cause the engine to run warmer than it should without an obvious explanation.\u003c\/p\u003e\n\u003cp\u003eThe EMP 46-00042 Water Pump Cup fits Mercury and Mariner V6 outboards in the 135 to 200 horsepower range across two specific production windows: 1989 to 1991 and 1999 to 2005. The gap in those years is not a typo, so verifying your model year before ordering is worth the extra minute. It is a direct replacement for Mercury part numbers 48752T and 48752. If you are cross-referencing from either of those numbers, you are in the right place.\u003c\/p\u003e\n\u003cp\u003eEMP manufactures this cup to OEM specifications for proper fit and consistent performance within the pump assembly. If you are doing a water pump service on one of these engines, the cup should be inspected and replaced if there is any sign of wear or distortion. Replacing it at the same time as the impeller is the kind of thoroughness that keeps the pump performing at full capacity and avoids a repeat job down the road.\u003c\/p\u003e\n\u003cp\u003eCompatibility and specs at a glance:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits Mercury and Mariner V6 outboards, 135 to 200 horsepower (1989 to 1991)\u003c\/li\u003e\n\u003cli\u003eFits Mercury and Mariner V6 outboards, 135 to 200 horsepower (1999 to 2005)\u003c\/li\u003e\n\u003cli\u003eVerify model year before ordering; fitment does not cover all years in this range\u003c\/li\u003e\n\u003cli\u003eReplaces Mercury 48752T and 48752\u003c\/li\u003e\n\u003cli\u003eBuilt to OEM specifications by EMP\u003c\/li\u003e\n\u003cli\u003eDirect replacement, no modification required for listed applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eNormalized SKU:\u003c\/b\u003e 4600042\u003cbr\u003e\u003cb\u003eUPC Code:\u003c\/b\u003e 840080469584\u003c\/p\u003e","brand":"EMP","offers":[{"title":"Default Title","offer_id":54081021542705,"sku":"EMP-46-00042","price":8.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0015\/7184\/8291\/files\/emp-water-pump-cup-mercury-48752t-46-00042-840080469584-1237373127.jpg?v=1778357792","url":"https:\/\/www.firstchoicemarine.com\/products\/emp-water-pump-cup-46-00042","provider":"First Choice Marine","version":"1.0","type":"link"}
