Winterizing question

[northwoodsPT]

I just bought my first boat this year..it has a 1995 90 HP mariner outboard. I am getting ready to winterize it for the first time. THe last time i used the boat this year i treated the gas with fuel stabilizer. Before i put in on the trailor, i disconnected the fuel line and basically ran the engine out of gas. Should i have done this before winter, or should i have left the treated gas in the engine. Also, any good sites or reading to recommend about the proper steps for winterizing?
Thanks
Andrew
