Honda BF9.9A/15A winterization

[illiniphoenix]

So I am new to outboard engines and will be winterizing my Honda BF9.9A/15A for the first time this weekend. I have compiled a winterization To-Do list based on my internet research, and I was wondering if there is anything I am missing? Here's what I've come up with:

Run the engine for 10 minutes to warm up (using a bucket)
Spray fogging oil in carburetor while motor is running
Turn off motor and let all water drain from the engine
When motor is cool enough, take out spark plugs and spray fogging oil in spark plug holes
Change the engine oil
Change the lower unit gear casing oil

Any tips/advice would be much appreciated!
