I suggest that downloading the Rotax manual for your engine may be useful.
The only ref I can find to operating temperatures is a table referring to oil
type
and the temperature ratings for differing SAE, apart from the maximums
obviously.
Perhaps it should be the Oil Temperature you should be considering.
As to any damage, not willing to speculate - sorry.

The other day, cruising at 9500' over the Great Rift Valley in Kenya, in Europa
5Y-LRY (Classic, Mono, 912 UL, 15 years old, 650 hours), the CHT was down at
55 C. I have very efficient radiators made by Docking Engineering at
Silverstone,
but never saw the coolant at this low temp. I use to blank off from time
to time, but then in the hot desert areas it goes up a bit higher, eg 110 C,
so I have to cater for all Kenya conditions. At 55 C it ran sweetly. Rotax
info tells me that the normal is 75 C to 110 C. Is any damage done at lower
temps?
