      Mercury Outboard Water Pumps and Impellers

      Functional 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 outboard water pumps with replacement Mercury outboard impellers to ensure a long lifespan for your boat’s engine.

      We have an extensive selection of full Mercury outboard water pumps, as well as the replacement parts and kits 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 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 outboard impellers for just about any marine engine.

      If you're unsure which water pump kit or Mercury outboard impellers you need, give our Parts Selector at the top of the page a try. Our parts selector lets you find the appropriate kits for Mercury water pumps or Mercury outboard impellers by serial number and model. This search tool will also allow you to see both aftermarket and OEM parts that are available for your engine.
