Prop question

[vep122]

I have a 120 hp force outboard. I found a used prop marked 48-78120 A4019p. Will this work on my motor? Your help is appreciated.

It depends on the year. There are 2 different lower unit types. It also depend the weight of your boat.

I'm sure no Force expert but I believe are 3 different versions off Force legs Early were non through hubs,later through hubs and some non through hub can use the through hub props.Then there are the late motors that I believe use a Merc leg and prop.
If we knew the years of your motor we might be able to eliminate some applications.
The prefix 48 indicates a Merc part number but may be intended for a Force motor the 19 indicates pitch.
