Here are a few hints on getting the Rotax data you want. 
 

Click on the link below. It will take you to the Document Retrieval area of the Rotax Owners Club web site where you may enter as a guest, or register as a "new user".  If you have the time, it is highly recommend that you register. Don't worry about this being a trick to get your email address. If you register, in the future, you will automatically get email notification when new Rotax Service documents are available. 

If you don't have the time to register now, just click the link below and login as a Guest. 

You will be given a search option. 

In this case, you are looking for a list of All 912 documents

When the search window appears, click on the "By Engine Model" button. 

A drop down menu will appear in the "Search By Engine Model" box

Click on the arrow and highlight "All Type 912 UL Engines", then the "Search" button.      The result will currently find a 7 page list of documents. 

Click on any you wish to view or save

You should only have to log in, as guest or registered user, once per session.
