Raw Water Pumps
A high-quality raw water pump for your boat will keep inboard engines in the right temperature range for the best performance. Visit Marine Parts Source when you need to replace a damaged pump. We carry replacement impeller pumps from all leading manufacturers, including Johnson Pump, Sherwood, Volvo Penta and JABSCO. Check the OEM part numbers and listed engine models in the product descriptions compared to your owner’s manual to confirm if the pump is the correct fit. Raw water pumps are also in stock for certain marine generators, so these power sources don’t overheat from extended use.
These engine cooling pumps are made of rugged corrosion-resistant materials like brass and bronze, ensuring many years of great operation with proper service. Shop for pedestal-mount raw water pumps, flange-mount pumps, crank-driven pumps and other designs that have the right ports for easy installation. We’re here to help you find the right pump at a competitive price, so contact us Monday through Friday.
