The ROTaX manual provides a power setting tables hopefully attached.
The 75% power equates to 5000rpm and 26 MP.

n. I believe that 75% power equates to 18.5 litres / hour in the cruise. In m
y Classic Europa tri-gear, this gives 115 to 120 KIAS cruise and is generall
y achieved around 4700 rpm, which agrees very well with Kevin Dilks' suggest
ed rpm "sweet spot". Certainly I don't enjoy the louder and less smooth crui
se at 5000 rpm.
