Cliff and anyone else who can help,
I installed a VDO water temp probe in the large hose, exiting the
coolant pot. Temps are reported at 190 to 220 degrees, which I consider
very good for the 912S, however, My CHT, as reported by the spark plug
probe, reads around 275, most of the time. I realize that the temp at
the base of the plug is probably the hottest spot on the engine, but is
this something I should be concerned about?
Has anyone used the Rotax supplied probe (the one in the head)
successfully with a VDO gauge? If so, will it hook directly to the VDO
gauge, or does it require some sort of adapter? What, if any,
difference should I expect in reported temps? Any help is greatly
appreciated...

the "hotspot" in the Rotax 912S. (you don't wnat it boiling over) I installed
a probe in the "coolant pot" using a alum nipple I had welded to the pot.
Now I read the hot water temp on CHT . ( just like oil temp)
