You've found a great website for tips, tricks and how-to's. Winterizing has been written about many times on this forum with lots of great info. Take a few minutes and acquaint yourself with the search feature and you'll likely end up with everything you want to know. Keep in mind, the info doesn't have to be specific to your boat - just to the systems you have on your boat. For example, you likely have a raw water cooled engine, not a fresh water cooled (FWC)/closed cooled system. But you'll need to verify that.
The link below should prove to be a decent guideline. But Denis' suggestion to use the search feature here is always a good idea. Most guys that post here give experienced & detailed insight to any subject.
