How do I winterize my outboard motor?. This is the first boat and Ooutboard I have ever owned and I am not sure where to find a checklist.

Here's a simple checklist for a 2-stroke outboard:
1) Flush it
2) Drain it
3) Fog it
4) Grease it

Chris, some aspects of winterizing are common to all motors, some are specific to particular types of motor, or even particular brands. If you can let us know what motor you have, you'll get the right info.

Thanks guys. It's a 1999 Johnson 100 hp two stroke. I tried three different sources for the manuals but none could be had.. Just to clarify... "fog it"?

So I am pretty clear on the lower unit winterization except the fog it part. What about the gas line? Do I disconnect it and run the motor dry of fuel? I have a 24 gal tank that is half full and has the right mix of Sta-Bil in it. It has an active VRO. Oh yea...it is heading towards the 30's here at night very fast so need to do this soon as my job has me travelling out West next week.

First off, "winterization" has nothing to do with the temperature, so don't sweat the cold nights. Assuming you have this on a trailer, you just want to make sure the motor is tilted all the way down so any water will drain. Winterization is rather the process of getting the motor ready to not be used for a while.

You want to stabilize the fuel and run it enough so it gets into the motor. Then, while the motor is still running, you want to spray fogging oil into the intake(s) until the motor stalls. Then remove the spark plugs, shoot some fogging oil into each plug hole, and kick the motor over on the starter (but don't start it) to distribute the oil.

Do NOT run the motor dry - just drain the carb bowls after you complete the fogging. Then change the lower unit oil, grease the grease points, give the whole powerhead a spray of WD40, and cover it up for the winter.

If it's getting below freezing make sure that the engine is stored in the "down" position so that the water drains out of the heads avoiding damage from freezing. Their is a complete check list for winterization at the outboardwizard.com, clk on the top left under "Articles" on the outboard wizard's home page.
