Just picked up a tempest plus prop for my Yamaha F150. Currently running a Yamaha 21m prop so I need a new hub kit for my tempest. After seeing/reading about excessive prop chatter with my new setup I am looking at the Flo Torq IV or rubex hub kits. (Also willing to look at other suggestions.) The rubex setup is pretty clear cut, however the Flo Torq IV is not. Since the only one they sell is for Mercury 4strokes and verados in the 150-175 range. Which means it should work well for what I am after, however I am unsure of the correct hardware I need?? Some guidance would be much appreciated! Thanks
