Quicksilver Water Pump Impeller for Mercury Mariner Outboards Impellers

The Quicksilver water pump impeller is a genuine Mercury Marine replacement part for Mercury and Mariner outboard engines. The impeller is the rubber vane component inside the water pump (also called a raw water pump or cooling pump). It moves water through the engine's cooling system to help prevent overheating during operation.

Key Features:

• Made by Quicksilver, the parts and accessories brand of Mercury Marine
• Designed as a replacement for worn, hardened or damaged impellers in Mercury and Mariner outboards
• Flexible rubber vanes seal against the pump housing to keep water flowing and cooling consistent
• Helps protect the powerhead from heat damage and costly repairs
• Suitable for routine water pump service and seasonal maintenance

Impellers wear over time, especially after running in sandy, silty or dry conditions. Replacing the impeller on a regular schedule keeps cooling performance reliable. Choose the specific part number that matches your engine from the available options.
