Has anyone installed a water thermostat?
Does Rotax have a minimum coolant temp published?
You should pretty regularly get over at least 212 F / 100 C for a period of time to drive the moisture out of your motor oil as a by product of combustion of gasoline.
There is no minimum coolant temp. The only reason I can think of for a coolant thermostat is if you want cabin heat from the coolant.
I have a thermostat-mixer from Silent Hektik im my current plane and like it al lot. There is no warming up and always perfekt temps on oil and water. No problems in almost 200 hours.
So I will put it in my current built, the RV-12iS. It will go in the next week and I can post pictures and data if someone is interested.

Not true.
Yes, it speeds up the process but moisture in the oil will be expelled at 185 degrees just as well as at 212 (especially at higher altitudes). It will just take a bit longer for any given amount.
There is a dramatic difference in cold weather warm up time between a 912ULS and a 912iS. The iS is much quicker.
Can you explain why this is?
