Nice thing is you do not have to do much with an outboard. I have a stern drive and I hate the winterizing. Anyway, when I had an outboard on another boat, I would always change the lower unit gear lube. Then I would hook it up to the flush muffs, get it running at a moderate idle, and spray storage fogging oil into the carbs, basically until it shut down the motor. I always used almost a whole can of the fogging oil. Then just lube stuff and put her away for the winter. Make sure you store it hanging straight down for drainage. Some may recommend running anti-freeze through it.
