I don't winterize. Of course, I boat throughout the winter, just usually once every 2 - 3 weeks, instead of more than once a week like in the summer. Only thing I do is change the gear lube before the first freeze, and store the motor tilted down, so water drains out of the cooling system, as opposed to leaving it on the motor toter in the spring/summer/fall months. All you should do is run stabil through, and fog the cyls. on top of what I do, and then replace the water pump impeller come spring. Or, pull it out and run it on muffs once every 3 weeks, and replace the impeller every 2 + years, and don't bother fogging it. Just bump start it (with kill switch pulled) to drain the rest of the water out after you do that.
