To generate a checklist of all 'potentially applicable' service bulletins, use the "Service Bulletins" option  in the SUPPORT/BULLETINS menu above ( direct link: https://www.rotax-owner.com/en/support-topmenu/service-bulletins )  and choose "By Engine Model" search option button and then select engine type 447 and date range 08/1991 to 04/2020. 

You can then cross reference the generated list with your engine logbook to see if the engine has been kept up-to-date over the years with any mandatory service bulletins. (You'll need to check inside each SB to see if it specifically applies to your particular engine configuration...)
