Mercury Water Pumps and Impellers for Sale
Functional Mercury water pumps contain impellers that work by pumping cool water through your engine to reduce friction and wear and tear for longer engine life. It should go without saying, well maintained working parts remain working optimally, and your engine will run well and last longer. That’s why Wholesale Marine always recommends Original Equipment Manufacturers (OEM) parts such as Mercury water pumps with replacement Mercury outboard impeller kits to ensure a long lifespan for your boat’s engine.
We have an extensive selection of full Mercury outboard water pump kits, as well as the replacement parts that go with them. Try finding your part number to locate the appropriate replacement if it’s still visible, depending on its age. If the part number is worn away, see if you can measure your Mercury impeller to narrow down the possibilities. You may not even have to replace the entire pump! Check to see if your impeller is functional first because that is often the culprit. If that’s the case, we also carry replacement Mercury impellers for just about any marine engine.

FAQs
How do I know when to replace my Mercury impeller or water pump?
Signs that your Mercury impeller or Mercury water pump needs replacement include overheating, reduced water flow from the outboard’s cooling system, engine alarms, or a rough-running motor. If you notice steam instead of a steady water stream from the telltale outlet, it's time to inspect and replace these components to avoid engine damage.
How do I find the right Mercury outboard water pump kit for my engine?
The easiest way to find the right Mercury water pump kit or Mercury impeller is to check your engine’s serial number and model. Use our Parts Selector tool to match your Mercury outboard with the correct replacement parts. If your part number is worn away, measuring the impeller’s dimensions can also help determine the correct replacement.
What are the benefits of using OEM Mercury water pumps and impellers over aftermarket parts?
OEM Mercury water pumps and OEM Mercury impellers are designed specifically for Mercury outboards, ensuring proper fit, durability, and performance. While some aftermarket parts may work, OEM components provide the highest reliability, reducing the risk of overheating, premature wear, or improper fitment. Using genuine Mercury replacement parts helps extend engine life and maintain peak efficiency.
