Product Details

The Sierra 18-3572 Upper Water Pump Housing Kit is a direct-replacement upper pump housing kit engineered for Mercury and Mariner V6 outboard engines. Designed to restore cooling system performance to OEM specifications, this kit directly replaces Mercury Marine OEM part numbers 817275A2 and 46-43024A3.

Sierra International has been producing marine engine parts engineered to meet or exceed original equipment manufacturer specifications, and this water pump housing kit is no exception. Built to withstand the demanding marine environment, it delivers a precise fit and reliable performance that technicians and boaters can count on.

Key Features:

  • Direct OEM replacement for Mercury/Mariner V6 outboard upper water pump housing
  • Replaces Mercury Marine OEM part numbers: 817275A2, 46-43024A3
  • Engineered to meet or exceed original equipment specifications
  • Manufactured by Sierra International to handle high-horsepower engine demands
  • Ensures proper coolant flow to protect your outboard from overheating
  • Complete upper housing kit — everything needed for a proper housing replacement

Routine water pump maintenance is essential to outboard engine longevity. Replacing worn or damaged pump housing components at regular service intervals helps prevent overheating, engine damage, and unexpected breakdowns on the water.

I wish it would show a time an date for delivery and I also needed to change my shipping address.

Great price! Very easy to find the correct part.

Easy to find replacement part, simple and efficient ordering process.

Seamless Purchase and great communication

I just placed my first order with Autoplicity and am extremely pleased with how smoothly everything went. It took an extra day or so to get me set up and verify my info, but they've left with me with the confidence future orders won't be an issue. Great prices and customer service is a winning combination.
