Mercury and Force 15S prop-the same?

[swimmin' for shore]

Trying to help someone out here-I have a 15 spline prop from a Mercury motor and he's wanting to buy it for his Force 120 with 4 1/4 inch case and 15S shaft. Will my prop fit for his motor?

If you check here at the prop store the 4 1/4" gearcase is a Merc prop numbers are the same whether your is the right pitch for the application is the question.
