After losing the service manual for my engine, then getting some help from people on this board (THANKS!), I did some "digging around" and found .PDF versions of Yamaha outboards from 1995-2006. For now, I have uploaded them all into a Google Documents account, so if you want to download any of them, or look at them online, feel free. They are .PDF files.
Once I found mine, I promptly sent it to Fedex Kinkos online and get a spiral bound printed version.
If there is any interest, I'll do more "digging" and get the 2007-2010 versions of the manuals as well.
Here are the 9.9 service manuals for 1995-2006
Year ..... Model ..... Manual
1995 ..... T9.9 ...... LIT-18616-01-24 - http://docs.google.com/fileview?id=0B6B ... OWEw&hl=en

Yamaha docs (http://www.yamahapubs.com/index.do
) says that the LIT-18616-01-83 manual covers the T9.9 engines from 1998 through 2006. If this information is not accurate, please correct me.
This is the first time that I have used Google Docs, so let me know if something does not work. The above links are supposed to bring you into the Google Docs online viewer, where you can view online or download the .PDF. I would suggest downloading the .PDF for your engine in case something goes kapoot with with online version at just the time you need the information.
