Its high-strength synthetic cords resist shock loading and stretching, while the moulded cog profile improves flexibility and increases cooling airflow. Specially compounded rubber helps transfer load evenly and maintain 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\u003e40 inches \/ 101.6 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\u003eResists shock-load failure\u003c\/li\u003e\n\u003cli\u003eMoulded cogs improve belt flexibility\u003c\/li\u003e\n\u003cli\u003eOpen cog profile helps reduce heat buildup\u003c\/li\u003e\n\u003cli\u003eSpecial rubber compression section distributes load evenly\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 MerCruiser sterndrive, Mercury Marine and OMC marine-engine applications that specify a corresponding 40-inch belt.

If your engine specifies OEM belt numbers 57-32850, 57-69143 or 311606, this is the direct replacement to have ready before launch. It also makes a smart onboard spare for extended cruising — a belt failure can simultaneously take out raw water cooling and battery charging.\u003c\/p\u003e\n\u003cp\u003eA belt that is close in length can still be wrong for the pulley system. Matching the original part number, belt width and accessory-drive arrangement helps prevent slipping, overheating and premature 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.
