Product Details

The Sierra 18-15550 is a premium cog-style marine V-belt designed to meet or exceed OEM specifications. Replacing Mercury/Quicksilver part number 57-13458T, this belt delivers dependable power transfer for marine engine accessory drives including alternators, water pumps, and power steering systems.

Construction & Materials:

  • High-strength synthetic cords resist shockload failure and provide low-stretch performance for consistent, uniform operation over the life of the belt
  • Special rubber compound compression section ensures smooth and even transfer of load forces to the cords
  • Polychloroprene rubber body with synthetic fiber fabric cover for oil resistance and temperature stability
  • Precision-molded cogs engineered to exact tolerances to improve flexibility and maintain cord support
  • Cog geometry provides increased surface area for air circulation, keeping the belt cool and preventing heat buildup in the cushion section
  • Rubber edges maintain positive, no-slip contact with pulley grooves for reliable energy transfer

Specifications:

  • Effective Length: 55 inches
  • Top Width: 29/64 inch (11.5 mm)
  • OEM Cross Reference: Mercury/Quicksilver 57-13458T

Sierra marine V-belts are engineered to OEM quality standards — correct in fit, form, and function — making this a direct, reliable replacement for aging or worn marine drive belts.

Best price online

I was searching around for a K&N cold air intake for my Tahoe. After searching Autoplicity had the lowest price hands down. I ordered on a Wed. evening, and it was on my door step Friday afternoon with standard shipping. I couldn't of asked for better service. The price was $100 cheaper than everyone else. I will be using Autoplicity again.
