Sierra V-Belt 18-15455 for OMC Stern Drive 908929 and Volvo Penta 3852464

The Sierra 18-15455 V-Belt is a replacement drive belt built for marine stern drive and inboard engine accessory systems. It is constructed with high strength synthetic cords engineered to resist shock loading, a common stress point on marine engines that see sudden throttle changes and vibration. The low stretch properties of the cord construction help the belt maintain consistent tension and uniform performance over its service life, reducing the slipping and glazing that shorten the life of lower quality belts.

This V-Belt has an effective length of 45 1/2 inches (115.6 cm) and a top width of 29/64 inch (11.5 mm), sized to drive accessory pulleys such as the alternator, water pump, or power steering pump on the engines it fits. It is a direct fit replacement for OMC stern drive and OMC inboard applications, as well as Volvo Penta stern drive applications that use the equivalent cross-referenced belt. Each belt ships as a single unit, ready to install in place of a worn or cracked factory belt.
