Product Details

The Sierra 18-70930 is a precision-molded marine cooling system hose designed to connect the water distribution block to the end cap on MerCruiser stern drive engines. Replaces OEM part number 32-52481.

Key Features:

  • Pre-molded design maintains full water flow through bends without kinking or collapsing
  • Constructed from EPDM tubing with synthetic knit reinforcement for durability and long service life
  • Engineered to OEM specifications — correct fit, form, and function
  • Compatible with both fresh water and raw water cooling systems
  • Simplifies installation with pre-formed bends that align directly to engine ports
  • Meets or exceeds original equipment standards

Sierra molded hoses are purpose-built for specific marine engine applications, eliminating the guesswork of cutting and routing bulk hose in tight engine compartments. This hose is designed for GM inline 4 and 6 cylinder MerCruiser stern drive applications and is a direct replacement for MerCruiser OEM part 32-52481.

Payment via Amazon is convenient.
