Kim,
My engine has done around 300 hours and I wasn't aware of the need to
service the gearbox at 200 hour intervals. All I can find on the Rotax
web site is SB-912-033 service bulletin which recommends inspecting the
gearbox at 600 hours if using avgas for more than 30% of the time. Can
you point me in the direction of the instructions for servicing the
gearbox?
Regards,
Richard.

Hello Richard!
I noticed that the replies to your vibration inquiry included everything
external. My 912, at about 400 hours started developing a significant
vibration that drove me nuts until I sent in the propeller speed
reduction assembly in for service. Upon disassembly, I noticed that the
primary gear set from the crankshaft to the driving dog was worn.
Whatever frequency was associated with that apparently translated to low
frequency vibration output to the gearbox and engine. I replaced the
gear set in addition to the usual servicing of the gearbox and this made
the engine smooth again. An internal problem, not external. I don't know
how many hours you have on your Rotax and if you have serviced the
gearbox at the recommended 200 hour intervals but this can make a
significant difference and has proven out in other Europas with same
complaint.
Good Luck and ...
Happy Skies!
