Engineered belts maximize power transfer to accessories.

Sierra serpentine belts are constructed using high strength synthetic cords that resist shock load failure and provide low stretch properties to assure uniform performance over the life of the belt. A special rubber compound is used in the compression section to transfer load forces a smoothly and evenly to the cords. Precise engineered cogs are molded into the belt to improve flexibility and increase air flow while maintaining cord support. The added air circulation helps to keep the belt cool and prevent heat buildup that can damage and cause the belt to wear prematurely. The design of the rubber edges maintains a positive no-slip contact with pulley grooves for consistent energy transfer.

Key Features

  • Low stretch synthetic cord construction provides uniform power transference and resists shock load failures
  • Molded cog design air flow to reduce heat build-up and maintain support at the contact points
  • Compression section features special rubber to smooth and even load forces
  • Rubber edges maintain no-slip contact with pulleys to maximize energy transfer
  • Available in sizes to fit many MerCruiser applications: Visit our Engine Parts Selector (below) to find the right belt for your engine.
