Product Details

The Sierra 18-3107 is a replacement water pump face plate (impeller plate) designed for Mercury and Mariner outboard engines. This precision-machined plate sits between the water pump impeller and the pump housing, providing a smooth, wear-resistant surface that is critical to maintaining proper cooling system performance. It is a direct-fit, OEM-quality aftermarket replacement engineered to meet or exceed original Mercury Marine factory specifications.

Key Features:

  • Direct replacement for Mercury Marine OEM part numbers 54705 and 32768
  • Designed to work in conjunction with the water pump impeller (Sierra 18-3007) for optimal cooling efficiency
  • Engineered to OEM-equivalent standards for reliable fit and performance
  • Also interchangeable with GLM 12520 and Mallory 9-43407
  • Sold individually

Regular replacement of the face plate during impeller service intervals helps prevent excessive wear and maintains the efficiency of the outboard's raw water cooling circuit. For best results, replace alongside the impeller, gaskets, and related water pump components.

OEM Cross-Reference: Mercury Marine 54705 | Mercury Marine 32768
