I do the same as ArtCarney - make sure to drain livewells as well. I've heard of people putting blocks under the trailer so the tires are off the ground...don't do that myself though. I don't run the engine out of gas, instead, I double up the dosage of sta-bil as the boat isn't going to be used until Spring. Also - I use sta-bil (marine formula) at every fill up to help with the ethanol.
