Prop part number question

[grizzly1530]

I am trying to find a replacement prop for a 1974 Mercury 650. When I search on here with my part number, 48-73134A4, it also comes up with part number 48-73134A40. Are these interchangeable? It seems all I can find anywhere are the 2nd one.

Correct the 48-73134a4 is the old prop number for the older style pressed in hub which has been discontinued by merc. The new 48-73134a40 will include the new flor-torq reflex prop hardware. It's also the same prop as quicksilver qa2074x . Just a heads up 73134A40 is Superseded to 73134A45

Awesome thanks! That helps a ton! So the current number is 73134A45?
