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

To detect a leak after fueling a gas-powered boat, a common test is the "smoke test." This involves introducing a non-toxic smoke into the fuel system and observing for any visible leaks. Additionally, a pressure test can be performed by pressurizing the fuel system and monitoring for drops in pressure, indicating a potential leak. Regular visual inspections for fuel odors or spills can also help identify leaks.
