The Rotax 912UL in my Kitfox 3, which was certified in 1992, has 760 hours on it. The date of Manufacture for my 912 is December 1990. Still going strong.

I just sold a 912UL that was built in 92, it was running strong after 10 years of sitting in a garage on the plane I flew home. the electrical system gave me fits and I finally bought a new engine but the old one had 710 hours on it and I put almost all of them on it. I think the core of the engine will easily go to 2000 hrs and likely longer. The guy who bought it will fix the electrical problem and fly it for years. I just didn't want to be the electrical guy, I'm not that smart.
I have a 93,912 with over1300hrs.The core is untouched,doesn't even need oil between changes.Unfortunatly someone in our regulatory body has had a brainfart and is pushing for strict adherence to the recommended calendar and overhaul times.A storm I brewing!
There is unsubstantiated stories of 912's in Australia with 4000+ hours.There has been a lot of research and data gathering by our overseeing organisation (RAANZ).These engines are extremely reliable well beyond design Limits.
