The Sierra 18-3444 Insert Cup is a precision-engineered replacement component for the water pump cooling system on Yamaha outboard engines. Also referred to as a cartridge insert cup, this part seats within the water pump assembly and works in conjunction with the impeller to maintain proper coolant flow and protect engine operating temperatures.

OEM Cross Reference:

  • Yamaha OEM Part Number: 63V-44322-00

Key Features:

  • Direct OEM replacement — meets or exceeds original Yamaha equipment standards
  • Engineered for reliable performance in harsh marine environments
  • Commonly included in Sierra water pump repair and rebuild kits
  • Sold as a single insert cup per package

The Sierra 18-3444 Insert Cup is a standard component found in numerous Sierra water pump kits, including the 18-3410, 18-3412, 18-3433, 18-3450, 18-3475, 18-3477, and 18-3479 kits. It is designed to be replaced during routine water pump service intervals to ensure continued cooling system efficiency and prevent overheating damage to the outboard engine.
