The Y series is the same as the X series.

X440, X640 and Y540 are all the same props with Low lift.

The Y540 should have been named X540.

12 are low lift ideal for submerged drive
X4 are medium lift general purpose props
M4 are like X4 but with the ears removed to unload the prop
Y are like X series but have 10% more pitch
X5 are general all purpose med lift prop
X6 are higher lift than X4 and suitable for surface/semi surface use
14 are moderatley high lift for hydros and deep V's
16 are high lift props for riggers and hydro's
17 are the highest lift prop for riggers and outboards
P7 are similar to 17 series but more rake and less lifti
19 are high lift for riggers and hydro's
V9 are moderate lift suitable for riggers, mono's and cat

ok......more confused.....I just received my stuff from OSE, of which I got some 7 cell IB4200's and a couple 42mm CF props.....so I figure I'll keep the 45mm CF prop on the Cat with an 11XL and 12cells and put the 42mm prop on the Titan with a 9XL and 14 cells.....the only smart thing is I did finally get a temp sensor....so I'll try the combinations and see which runs cooler? ...also the receiver balloons Steven sells are awesome, definitely recommend them.
