My best guess is that it would not be permitted to
fly under IFR at night; because the Rotax 912 is not certified to a
standard
compatible with night IFR.

huh? What's the night IFR standard for a certified engine?

I couldn't remember it at the time of my post, but someone else did--part
33. And IIRC, it's part 35 for the prop.

Is there a particular part of Part 33 that is applicable to night IFR?
I searched for "IFR", "night", a "instrument" without finding any
specific certification standards for night IFR.

What engine certification standard would be compatible with Day VFR
and *not* also be compatible night IFR?

Rotax themselves made the engine in question unqualified for night by
stating that the engine was for Day VFR only.

Does anyone know if there was a technical reason for the restriction?

The general feeling on the Rotax boards that I was reading at the time
(I was considering one for my 601XL) was that it was pure CYA for liability.

This seems reasonable, considering the few changes between the 912ULS and
the night, IFR-certificated 912S...it wouldn't surprise me to discover most
of the $8000 price difference between the two goes to a liability insurance
fund.

: the Mermaid. It is built by CZAW and they have some issues pending.
I'd look into that before I went any further.

Really? I had not heard of any issues with the Mermaid. Care to share?

No because what I've heard and read are secondhand at best and I don't
repeat that stuff. The issues weren't with they any aircraft CZAW makes
but with the company itself.

It's been a while. Maybe the problems have cleared themselves or never were.

In short, you're lying then.
