Who is responsible for bringing Service Bulletins to our attention? The
factory? Rotax? I do look at the website every so often but I have already
missed 2 bulletins by being out of time. It is a good job I am not flying
yet!

> I just complied with the Rotax mandatory service bulletin by replacing my
coolant with the new NPG+ coolant - waterless. The concept is simple - the
coolant now has a boiling point of 375 degrees F so there is no possibility
of boiling over should the CHTs approach the 275 degree F limit. I have
three flight with it now and I can say that the temps are running warmer
than they have in the past. I am not sure this is a good thing, since it is
now winter and the air temp is cool. I suppose I will see what happens when
we warm up again. My engine monitor reads about 10 degrees high, so I am
seeing 240 degrees where I would normally see about 230 in climb. The CHTs
also seem to come up faster taxiing out, but the oil temp doesn't warm up
any faster.

and found that my exhaust leak may have been coming from the flange where
the exhaust goes into and out of the turbo. I have carefully planed those
surfaces and reassembled it. I have had no CO detected in the cockpit since
then and will be looking at the area around the turbo to see if there is any
more evidence of leakage there.
