What test can be performed to detect a leak after fueling a gasoline-powered boat?

The sniff test is a commonly utilized method to detect leaks after fueling a gasoline-powered boat. This test involves using your sense of smell to identify any gasoline odors that may indicate a fuel leak. Since gasoline has a strong and distinctive smell, it can alert the operator to the presence of a leak in the fuel system.

This method is practical and can quickly signal the need for further inspection or action. If gasoline is present outside of its intended containment, such as in the bilge or around fuel lines, it poses a significant fire hazard and must be addressed immediately.

While other methods like visual inspections can be important for spotting obvious leaks, and pressure tests and water tests can evaluate the integrity of various systems, they may not be as immediate or effective in detecting gasoline fumes specifically, which is critical for safety on the water.
