How does an outboard motor water pump work?
An outboard motor water pump operates by drawing water from the body of water in which the boat is submerged. As the engine runs, the pump's impeller spins, creating a vacuum that pulls water into the pump housing. The impeller then forces the water through the cooling system, circulating it to cool the engine and expel excess water through the exhaust. This continuous flow prevents overheating and ensures the engine operates efficiently.
