High-strength synthetic cords resist stretching and shock-load failure, while the precision-moulded cog profile improves flexibility and allows greater airflow around the belt. Its specially compounded rubber construction provides smooth load transfer and 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\u003e47 inches \/ 119.4 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 synthetic tension cords\u003c\/li\u003e\n\u003cli\u003eLow-stretch construction supports consistent performance\u003c\/li\u003e\n\u003cli\u003eMoulded cogs improve flexibility and cord support\u003c\/li\u003e\n\u003cli\u003eOpen cog profile helps reduce heat buildup\u003c\/li\u003e\n\u003cli\u003eRubber edges provide positive, non-slip 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 and OMC marine-engine applications that specify a compatible 47-inch V-belt.

Do not force the belt over the pulley flanges. Set belt tension according to the engine manufacturer's specification, rotate the drive by hand to confirm correct seating and recheck the tension after the initial operating period.\u003c\/p\u003e\n\n\u003ch2\u003eAlternate \/ Superseded Part Numbers\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSierra part number: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\u003e18-15470\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eSupplier or catalogue reference: \u003cstrong\u003e47-15470\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMercury MerCruiser: \u003cstrong\u003e57-78200\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMercury MerCruiser: \u003cstrong\u003e57-78200A1\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMercury Quicksilver: \u003cstrong\u003e57-78200Q1\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eOMC: \u003cstrong\u003e0509309\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eRedline: \u003cstrong\u003eRL15470\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eUPC: \u003cstrong\u003e030999566591\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 and OMC inboard and sterndrive boats. If your engine specifies OEM belt numbers 57-78200, 57-78200A1, 57-78200Q1 or OMC 0509309, this is the direct replacement to have ready before launch. It also makes a practical onboard spare for extended cruising — a belt failure can simultaneously take out raw water cooling and battery charging.\u003c\/p\u003e\n\u003cp\u003eBelt length alone is not enough to confirm fitment. Matching the original part number, belt width and pulley arrangement helps prevent slipping, overheating and premature accessory-drive wear. Always verify the OEM belt number and pulley configuration before ordering.\u003c\/p\u003e\n\u003cp\u003eFor a complete cooling system service, pair this belt with a raw water pump impeller replacement.
