I'm Having Trouble ID'ing A SS Prop

I bought a locked up lower end from a 1991 Force 150. It came with a stainless steel prop in good condition. $25.

The part number on the hub says "384702". A number on the outside of the hub says "K1531".

The prop is 12 3/4" X 21P.

I ran some searches and got nothing on the K1531 number.

Searching the "384702" number brought up this in a couple of places:

Manufacturer: Evinrude / Johnson / OMC
Prop Family: SST
Material: Stainless Steel
Part: #384702
Blades: 3
Diameter: 12-3/4
Pitch: 21

Another seach had this P.N. as a 13 spline, yet it's a 15 spline Force/Mercury.

Q1: Does the "384702" refer to the prop without the hub?



I'm also trying to figure out if this prop will work on my 1997 Force 120 HP.

I did some checking and found the same prop P.N.'s listed for both 120 HP and 150 HP Force motors.

Q2: Will this prop work on a 1997 120 HP Force?

Any expert feedback on this?
