Hello Phil,
You dont have much of a choice, there are only 2 gear ratios for the
Rotax 912. The 80 hp version has 2.27, the 100 hp version slightly
different. A variable pitch prop is the only way to go in the Pulsar
if you want to maximize performance. The 64 GSC in flight adjustable
is a good choice. My XP has about 1000 h on it with this prop.
Performance (measured/estimated):
Best rate of climb about 1050 fpm at gross weight, sea level, standard
conditions.
Cruise speed: 125 KTAS at 3.0 gal/h
133 KTAS at 3.5 gal/h.
138 KTAS at 4.5 gal/h
Range (18 gal total): 4.8 hours plus one hour reserve at 3.0 gal/h
--> 550 nm no wind
4 hours plus one hour reserve at 3.5 gal/h --> 500 nm no wind
2.8 hours plus one hour reserve at 4.5 gal/h --> 372 nm no wind
Take off distance: <1000 ft ground roll at gross weight, sea level
hard surface 1500 ft over 50 ft obstacle
Landing distance 1500 ft with slow approach

Hi Sonja,
I got hold of GSC a while ago(different team)and he said
they had discontinued the manufacture of the in flight adjustable, but still
had the jigs, but things might have changed again. I had two, one spare,
they serviced my first one and offered me the new version for a very nominal
fee.
Regards
