Serpentine Belt 27.362 Long 6 Rib

The Serpentine Belt 27.362 Long 6 Rib from Jones Racing Products is engineered for marine engines that demand reliable accessory drive performance in saltwater and freshwater environments. Whether you're running a performance boat, commercial fishing vessel, or recreational cruiser, this serpentine belt maintains consistent tension across alternator, water pump, and power steering systems—critical for hours on the water where engine reliability directly impacts safety and catch success. A properly functioning serpentine belt ensures your charging system stays topped up during long runs and your cooling system operates without interruption.

Jones Racing Products engineered this 6-rib design to maximize surface contact and distribute load evenly across accessory pulleys, reducing slippage and heat buildup under sustained engine operation. The 27.362-inch length is precisely calculated to fit specific marine engine configurations, ensuring proper belt tension without custom shimming. The 6-rib groove pattern provides superior grip compared to older poly-v designs, while the belt's compact 0.15 lb weight reflects its efficient synthetic construction—materials chosen to resist degradation from UV exposure, ozone, and the corrosive effects of marine environments where rubber compounds fail prematurely.

Anglers and boat operators benefit most from preventative belt replacement during routine engine service—catching a worn or cracked serpentine belt before it breaks keeps you from getting stranded offshore or losing fish during a critical season. Installation requires verification of your specific engine's factory belt routing diagram; the 27.362-inch dimension must match your vessel's original specification exactly for proper pulley alignment and tension. This replacement belt is ideal for Mercury, Volvo, Yamaha, and other marine power plants that use Jones Racing's OEM-equivalent specifications, making it a straightforward bolt-on component for DIY maintenance or professional service work.
