I think going down to a 17p prop is a good idea, to get the results you are looking for. I would stick with stainless if possible. I am not sure if the yamaha prop is the same hub as your force. google it!

The Yamahs K series are for 4.25 hub, 15 spline units. They have pressed in hubs.

They should fit on your Force 120 (with Mercury lower unit). Going to a 17" could put you over your rpm limit(5250).

An 18 pitch would be better based on the 5000 rpm with a 19".
