Does anyone have pictures of 912S installation.
Particulary lower front vent connection with cooling air baffle, and lower cooling mod.
Thanks

Yes Ron, the CRP of the panel is transparent to GPS unless you re-did
your panel in carbon fiber. The plexi windshield is also transparent to
GPS.
Unless you metalized your firewall, it too is essentially transparent.
GPS Antennas are not supposed to "see" down to the horizon, in fact
most receivers with ignore satellites within 5-10 degrees of the horizon
("the masking angle") by orbital calculation in order to avoid atmospheric
distortions of the signal. Since your engine is below the inside ceiling
of the panel, the existence of the engine is a non-factor as well.
My GPS puck is attached to the ceiling of my panel with industrial grade
double sided foam tape.
Ivor, your solution requires extra length of coax cable and a connection to be broken whenever you need to pull the panel out of the fuse. Extra
coax length and in particular, extra coax connections are extremely hurtful
to GPS signal strength.

I am not certain I understand what you are looking for.
In my more or less standard factory design installation of my 912s
there is only the aluminum dust from the lower cowl large entrance.
In my case I have modified this radiator cooling flow by bolting a
rectangular aluminum plate to the bottom of the lowest radiator forward,
horizontally to the point where the plate (about 50 thou) touches the floor
of the duct, i.e., the bottom cowl. The purpose of the flat is to force
the airflow through the radiators instead of through the existing gap
between the radiators and the cowl.
Rotax has a "cooling baffle" which is applied to the top of the engine
and is designed to redirect air flow from the frontal air apertures down
through the cylinder cooling fins. It does not connect to the bottom duct,
unless someone has gone experimental. The baffle is probably
not useful for 912s installation which tend not to overheat in Europa's,
but rather for the 914 which is otherwise prone to overheating.

IRA,
my question is : Is it necessary to used cooling air baffle. To day my 912 UL temp are low , about 90° celcius.
Do you use cooling air baffle or not ?
Thanks
If it is necessary do you
