Older 912 longevity was created by ChuckGant
Hello. I’m new to Rotax engines, new to this forum, but not new to general aviation. I’ve been lurking here for awhile trying to get smart on Rotax engines. Please bare with my rookie questions.

I am seriously considering buying a Rans S-7 built in 2006 that has a 912 ULS with a 1500 hour TBO. The service bulletins indicate that it requires a new case to increase the TBO to 2000. It currently has 1200 hours on the engine.
1. Any significant issues I should know about an engine of this vintage?
2. Am I taking a big risk buying a 912 with this many hours?
3. Anything particular to look for on this engine when I go to look at the airplane?

It has had the carb inspection, gearbox inspection and 5-year rubber done within the last 50 hours.

Thanks in advance for any education you can give me before I commit to this purchase.

The serial number of the engine is: 5643446
The serial number of the crankcase is: 20647
