Product Details

The Sierra 118-70943 is a molded cooling system hose designed to connect the thermostat housing to the port exhaust manifold on MerCruiser 7.4L, 454 Mag, and 502 Mag engines. Sierra molded cooling system hoses are engineered for fresh water or raw water cooling systems, molded to provide full water flow through bends while ensuring ease of installation, with OEM quality that is correct in fit, form, and function.

Key Features:

  • EPDM tubing construction with synthetic knit reinforcement
  • Pre-molded design eliminates kinking and ensures optimal coolant flow
  • Direct OEM replacement quality for reliable, long-lasting performance
  • Designed specifically for marine engine cooling systems

This hose replaces OEM part number 32-89749-1, making it an ideal replacement for worn or damaged original equipment hoses on compatible MerCruiser stern drive applications.
