What should you do when feeling in outboard boat with a portable tank?

If you feel an outboard boat with a portable fuel tank, first ensure the tank's vent is open to prevent a vacuum. Next, check that the fuel line is securely connected and that there are no leaks. Start the engine according to the manufacturer's instructions, and monitor for any signs of fuel issues. Always prioritize safety by wearing a life jacket and having a fire extinguisher on board.
