OS & YS Engine Manuals...
Here is my collection of OS and YS engine manuals...I use to have them uploaded to a free hosting website but it's gone down the tubes...I wasn't aware you could upload PDF files here...This will be much better... 
Some of these are kinda big files so they may take a while to load on slower networks..
You can use Adobe reader to view them which you can get from here:
http://www.adobe.com/products/reader/
To save to your computer just click the little floppy disk lookin' thingy in the upper left corner of the window (next to the printer lookin' thingy)...
We'll start with the Hanno Manual (good tuning info), Hanno RCM Review and OS horsepower ratings:

RE: OS & YS Engine Manuals...
Some of these manuals may look familliar to you since many of them (the good ones) were written by Clarence Lee. Clarance, is without a doubt, the most knowledgeable engine man ever, and is still sitting on a backlog of manuals that he has been contracted to write. He is also one of the finest people to ever flip a prop and I cherish every moment I have been able to spend with him.
