Help with Prop

I need a new prop..I broke mine Sunday.

I am confused as to what to get.

I know my part # and I found some that may fit. But they are showing "45" at the end of the part # and mine shows "40"

I know it is 14 pitch

I have these to choose from

Part #

The 40 & 45 are just different series, basically the same props though.

Thx, I ordered the 10.25 14 P prop today
