How do I drain my fuel tank?

I have a Captiva 226 that has 3 year old gasoline in the tank. Although I did use the gas StabBil I really don't have the confidence to take the boat out on the lake. Is there an easy way to drain/siphon/empty the tank?

but octane boost and heat should be fine
Siphon and hand pump !
