Isn't a High Five SS five blade prop even better? That is what we have on our boat (1994 Wellcraft 196S with a 5.0 Mercruiser). It seems to really launch the boat fast and have good top speed.
im not sure and i need a spare prop anyway. I think the blade area on my high 5 seems smaller then the blade area on my old 4 blade ss i had on my yam 115
