High Cotton, If you are looking for rough water performance go with a lower pitch prop. The lower pitch allows you much more responsiveness while navigating in the rough stuff. If youve got to get a jump to clear the next wave the smaller prop will give you the ability to do that. By far the best rough water prop Ive run is a Hydromotive Quad IV X OB. Its a large diameter prop with 4 blades and similar to mercurys bravo line. If you trade the 27 fury for a 25 fury you would probably be shocked at how much easier the boat drives in rough water and youll probably get addicted to the neck snapping hole shot and midrange performance while in smooth water. I know that is what happened to me. Chris CoupelPaulina, La.Chris CoupelPaulina, La.
