Product Details

The Sierra 18-3127 Impeller Plate (OEM cross-reference: OMC 319275) is a precision-engineered water pump component designed as a direct replacement for Johnson and Evinrude outboard motors. This impeller plate serves as the critical sealing surface within the water pump assembly, working in conjunction with the impeller to maintain proper water flow and prevent engine overheating.

Sierra's impeller plates are manufactured to meet or exceed original equipment manufacturer (OEM) specifications, ensuring a precise fit and reliable long-term performance. This plate is a common service part found in water pump rebuild kits for Johnson/Evinrude 3-cylinder 2-stroke outboards.

Key Features:

  • Direct OEM replacement — replaces OMC part number 319275
  • Engineered to meet or exceed OEM specifications for fit and function
  • Essential water pump component for maintaining proper engine cooling
  • Compatible with Johnson/Evinrude outboard motors (see fitment data)
  • Sold individually — can also be sourced as part of a complete water pump rebuild kit

Cross-Reference Part Numbers: OMC 319275 | Sierra 18-3127 | SIE 3127 | SIE18-3127 | 01-1654 | 0418-3127

Regular water pump service is critical to outboard engine longevity. Replacing the impeller plate during routine impeller service ensures a proper seal and consistent coolant flow to the powerhead. This part is a standard component in Sierra water pump kits such as the Sierra 18-3389.

I would like to have used Paypal (not the credit card) but could not.
