Dear Richard,
thank you for renewinging this question. N81EU has now 1.ooo hrs on the
Hobbs and with a modified cooling system. She has flown between the
arctic and the Sahara with sometimes vy low Oil / CHT temps. I do not
see any damage to the engine (e.g. compression), but will like to hear
more input on this.
greetings from the other side of Africa

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?
