What should you do before starting the engine after fueling?

Before starting the engine after fueling, it is crucial to sniff the bilge and engine compartment for fuel vapors. This step is important because fuel vapors can be highly flammable and pose a significant explosion risk if the engine is started in an environment with fuel vapor present. Detecting fuel vapors beforehand allows you to address any potential leaks or issues, ensuring a safer environment before initiating any engine functions.

Checking for fuel vapors helps in taking necessary precautions, such as ventilating the space adequately or resolving any leaks, thereby enhancing overall safety on the water. This practice is an essential part of boat operation training and reflects a responsible approach to boating safety.
