{"product_id":"sierra-v-belt-47-15400","title":"Sierra V-Belt 47-15400 — Marine Inboard Sterndrive","description":"\u003cp\u003eThe Sierra 47-15400 is a cogged V-belt designed for accessory drive systems on marine inboard and sterndrive engines. Its notched construction improves flexibility and heat dissipation compared to a standard wrapped belt, making it well suited to the confined, high-temperature environment of a marine engine compartment. The belt drives one or more engine accessories — typically the alternator, raw-water pump, or power steering pump — depending on the pulley configuration of the specific engine.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-strength synthetic cords resist shock-load failure\u003c\/li\u003e\n\u003cli\u003eSpecial rubber compression section for smooth, even load transfer to the cords\u003c\/li\u003e\n\u003cli\u003ePrecision-molded cogs improve flexibility, maintain cord support, and allow air circulation to reduce heat build-up\u003c\/li\u003e\n\u003cli\u003eRubber edges maintain positive, no-slip contact with pulley grooves\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplication Compatibility\u003c\/h2\u003e\n\u003cp\u003eDesigned for marine inboard and sterndrive engines that specify a cogged V-belt in the accessory drive. Confirm the original belt part number, cross-section, and outside circumference against your engine service documentation before ordering. Engine builds can vary by model year, horsepower rating, and accessory package.\u003c\/p\u003e\n\n\u003ch2\u003eFitment Notice\u003c\/h2\u003e\n\u003cp\u003eDo not substitute by approximate length alone. Confirm the belt cross-section and pulley groove profile before installation. An incorrect belt width or length can result in slipping, premature wear, or accessory failure.\u003c\/p\u003e\n\n\u003ch2\u003eWhen This Part Needs Replacement\u003c\/h2\u003e\n\u003cp\u003eReplace the belt when it shows cracking, glazing, fraying, missing material, oil saturation, or persistent squealing under load. A belt that rides low in the pulley groove or requires repeated tension adjustment is likely worn and should be replaced before it causes charging or cooling problems on the water.\u003c\/p\u003e\n\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eInspect all pulleys for wear, corrosion, misalignment, and contamination before fitting the replacement belt. Route the belt without forcing it over pulley flanges, then tension to the specification in your engine service manual. Rotate the drive by hand to confirm correct seating and recheck tension after the initial run-in period.\u003c\/p\u003e\n\n\u003ch2\u003eAlternate Part Numbers\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSierra part number: \u003cstrong\u003e47-15400\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eBarcode: \u003cstrong\u003e30999566454\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003eThe 47-15400 cogged belt is the right choice for accessory drive positions that specify a notched V-belt profile — the cog design runs cooler and flexes more easily than a wrapped belt, which matters in tight marine engine compartments where heat and space are both limited.
