Product Details

The Sierra 18-70927 is a precision-molded marine water hose designed to connect the thermostat housing to the port exhaust manifold on MerCruiser GM V8 log-style cooling systems. Built from durable, marine-grade materials, this preformed hose maintains its shape and seals reliably in demanding freshwater and saltwater environments.

This hose is a direct OEM replacement for Mercury/MerCruiser part number 32-73795, ensuring a proper factory-spec fit without modification. Sierra engineered this part to meet or exceed original equipment quality standards, providing long-lasting performance you can count on.

Key Features:

  • Replaces MerCruiser/Mercury OEM part number 32-73795
  • Fits GM V8 5.0L and 5.7L log-style cooling systems (port side)
  • Routes from the thermostat housing to the port exhaust manifold
  • Pre-molded construction for precise fitment with no cutting or reshaping required
  • Built with high-quality, marine-grade materials to withstand harsh marine environments
  • Meets or exceeds OEM specifications

When replacing aging or cracked cooling hoses on your MerCruiser inboard or sterndrive, the Sierra 18-70927 delivers a reliable, drop-in replacement that installs quickly and restores proper coolant flow to your engine's cooling circuit.

Quick and fast

Excellent price, and in stock!! Received fast, not the first, will not be the last time I look to Autoplicity for auto parts.

Found the part I was looking for quickly and the check out process a seamless.

Great

Great price. Hoping it works on my car

So Far so good.

No problem

Only downside is I couldn't use multiple coupons - one for shipping discount and another for 10% off.

Autoplicity created a great shopping experience. It was very easy to find the parts I needed for the vehicle I needed. I will definitely use Autoplicity again!
