You can always siphon out the fuel into some other container to drain it. If you have a primer bulb, take the engine connector end off and pump the bulb to get the fuel flowing and let it drain the tank into some other container. And if that other container is lower then the tank, it will empty the tank. I personaly have never seena valve drain on a boat tank myself. Others may have, but I haven't. JMHO
