Marine Circulation & Raw Water Pumps

Regardless of whether your engine has an open or closed cooling system – the engine’s raw water pump is a critical part of keeping the engine cool. The circulation water pump draws “raw water” (any water the boat is sitting in) through the boat’s seacock and pumps it through the engine before exiting with the exhaust – cooling the engine as it passes through and keeping it from overheating. Fisheries Supply stocks marine raw water pumps from trusted brands like Jabsco, Johnson Pumps, Sherwood and Oberdorfer Pumps – so shop today and protect your engine!
