Looks similar to the Suzuki motors and gearboxes that are being sold by Vasilli in Canada. Raven redrives also did some Suzukis with a belt drive. I tried one in my old aircraft and it never delivered the power that I was hoping for with the 3 cyl version. I bought a 4 cyl that is supposed to develop about 85 hp but as the specs show it is slightly heavier than the 912. There were a few used in Zenair 701s and I saw one in a Rans S7 but not many super reliable conversions. I really wanted to be one of the reliable motor conversions but in the end I found a 912 that is all I was hoping it would be. I have just over 200hrs in the past year and the Rotax has not missed a beat. A used Rotax 912 gets my vote for best value and reliability.

Possibly, worth a look?
