Why do boat engines overheat? Overheating can also be caused by a worn or damaged water pump impeller. … Any debris left in the water passages may reduce flow, which leads to persistent overheating. When a new impeller is installed, run the engine or related system as soon as possible to ensure proper operation, as I learned from experience.
What makes a boat motor overheat? The most common cause of outboard motor overheating is water pump failure. … Water pump failure can also be caused by a defective heat exchanger, though this is harder to check. Generally, if it is not a problem with lack of raw water flow or fresh water, the heat exchanger will be the cause.
How do you cool a boat engine? Raw water refers to the water that the boat is floating in. It makes no difference whether it is salt or fresh, both are used to cool the engine. The process starts by drawing water into the engine through a seacock fitting and pumping it through the engine’s water jacket and ports by way of a mechanical water pump.
Why does my boat overheat at idle? At idle there isn’t enough vacuum to pull enough water through but as engine speed increases the vacuum builds and it starts circulating enough water to cool it back down. Check all your hose clamps, water strainer gasket, etc.
