In the event of a boat motor fire, what should be done first?

In the event of a boat motor fire, the most critical action to take first is to shut off the fuel supply. This is because fuel can act as a significant contributor to a fire, and stopping the flow of fuel helps to prevent the fire from escalating. By cutting off the fuel supply, you reduce the chances of the fire spreading further and minimize risk to yourself and others on the boat.

Addressing this emergency effectively hinges on the idea that controlling fuel sources can help mitigate the situation. Once the fuel is shut off, further safety measures can be taken, like calling for help or using fire extinguishers to combat the flames if safe to do so. It's essential to prioritize actions that directly impact fire safety in emergencies, particularly with the inherent dangers of flammable materials in a boating environment.
