We have a Stemme S-10 with the 115HP, 1200cc, turbocharged Rotax 914 engine. It works hard launching our glider and has a 5 minute take off limit of 115HP. Then power must be reduced to 100HP.
This is an interesting engine and it has some interesting requirements.
It requires 91 (R+M) / 2 octane unleaded without ethanol. So 90 octane "rec" fuel won't work. I use 96 octane VP C-9 fuel. While it's OK to use 100LL, they strongly recommend that it's not be used. Due to corrosion, deposits, shorter engine life and oil issues.
It also requires a semi or full synthetic "motorcycle" oil with GL5 or similar rating for gears. Mobil 1, 10W-40 and 20W-50 syn motorcyle oils are at the top of the list of recommended oils!
