Greetings,

I recently acquired an even older 912UL than I had already.  The one I just got is 4005342, from about Summer of 1992 I believe.  I noticed that the gear box has what appears to be a magnetic plug, but on the newer (yet still really old) engine 4405028 (2002) there is just a flat spot in the casting that wasn't machined. 

What's the story with the extra plug?  Did they decide it wasn't needed later, or does it designate that the gear box is different in some other way?  This is 90% for curiosity, and 10% to make sure it's safe to remove it to peek inside.

Thanks,

Rusty (antique 912 collector)

    This gearbox should be placed in a museum!

    That gearbox is from quite an old version, and it's been a while since we've come across one like that. Rotax made the decision not to include a MAG plug in that spot anymore, as it wasn't gathering any material. The current position of the MAG plug is the most suitable as it's located right next to an oil passage in the crankcase where it can collect the most material.
