Re: force 125hp prop.
Other than the Comprop, I don't think there are ANY four blade props available. However: If you are open to experimentation (expensive with props) You can check out Merc and Honda props. Reason: if you check the catalogs, The Michigan number is the same for Force and Honda props. Therefore props from other manufacturers for Honda should fit Force. (Should, could, would--If the bulldog had sneakers, if the Gorilla had T*Ts) Hub needs to be 4 1/4 inch diameter and splines need to be 15. Then of course, you need to check hub length. And I think in a previous thread here someone used a Vortex prop. I don't remember--Check back a few days.
