How do you drain bad gas from a 1998 boat?

To drain bad gas from a 1998 boat, first, ensure the boat is on a level surface and turn off the fuel supply. Locate the fuel line and disconnect it from the fuel tank, allowing the old gas to flow into a suitable container. If equipped, you can also use a fuel siphon pump to remove the gas. Finally, replace the fuel filter and refill the tank with fresh gas before restarting the engine.
