High-strength synthetic cords provide low-stretch performance and resistance to shock loading, while the precision-moulded cog profile improves flexibility and promotes airflow to reduce heat buildup. Specially compounded rubber transfers drive loads evenly and maintains dependable contact with the pulley grooves.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMarine replacement cogged V-belt\u003c\/li\u003e\n\u003cli\u003eEffective length: \u003cstrong\u003e48 inches \/ 121.9 cm\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eTop width: \u003cstrong\u003e29\/64 inch \/ 11.5 mm\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eHigh-strength, low-stretch synthetic cords\u003c\/li\u003e\n\u003cli\u003eMoulded cogs improve flexibility and cord support\u003c\/li\u003e\n\u003cli\u003eOpen cog profile promotes cooling airflow\u003c\/li\u003e\n\u003cli\u003eRubber edges maintain positive pulley contact\u003c\/li\u003e\n\u003cli\u003eSupplied as one replacement belt\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eEngine Compatibility\u003c\/h2\u003e\n\u003cp\u003eDesigned for selected Mercury MerCruiser V-belt accessory-drive systems, including certain 5.7L, 7.4L and 8.2L V8 applications.

Squealing, slipping, repeated loss of tension or a belt riding unusually low in the pulley groove can also indicate belt wear, pulley wear or incorrect fitment.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eInspect the pulleys for corrosion, contamination, wear and misalignment before installing the replacement belt. Do not force the belt over the pulley flanges. Set the tension according to the engine manufacturer's specification, rotate the drive by hand to confirm proper seating and recheck the tension after the initial operating period.\u003c\/p\u003e\n\n\u003ch2\u003eAlternate \/ Superseded Part Numbers\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSierra part number: \u003cstrong\u003e18-15480\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eSupplier or catalogue reference: \u003cstrong\u003e47-15480\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMercury MerCruiser: \u003cstrong\u003e57-48122\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMercury Quicksilver: \u003cstrong\u003e57-48122Q\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMallory: \u003cstrong\u003e9-55003\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eGLM: \u003cstrong\u003e89440\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eRelated OMC reference: \u003cstrong\u003e0509295\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eUPC: \u003cstrong\u003e030999566614\u003c\/strong\u003e\n\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 belt is the right choice for pre-season service and routine maintenance on MerCruiser 5.7L, 7.4L and 8.2L V8 inboard and sterndrive boats running a conventional V-belt accessory drive. If your engine specifies OEM belt numbers 57-48122 or 57-48122Q, this is the direct replacement to have ready before launch. It also makes a practical onboard spare — a belt failure can simultaneously take out raw water cooling and battery charging.\u003c\/p\u003e\n\u003cp\u003eA 48-inch belt is not automatically the correct belt. Match the original part number, belt width and pulley arrangement before ordering, especially on older engines that may have been modified or repowered. If your engine has been converted to a serpentine-belt system, this belt does not apply.\u003c\/p\u003e\n\u003cp\u003eFor a complete cooling system service, pair this belt with a raw water pump impeller replacement.
