What is the recommended action if a boat's engine starts to overheat?

If a boat's engine starts to overheat, the recommended action is to shut off the engine and check the cooling system. This is crucial because continuing to operate an overheating engine could cause severe damage, including warping or even seizing of engine components. By turning off the engine, you prevent further heat build-up and allow for a more thorough inspection of the cooling system, which may include checking for blockages, leaks, or issues with the water intake that could be causing the overheating.

Addressing the cooling system directly helps to identify the root cause of the problem, allowing for necessary repairs or maintenance to restore proper engine function. It's important to prioritize the engine's health and avoid the risks associated with overheating, which can lead to costly repairs and safety hazards out on the water.
