OK peeps hows it going.21 1/2 aftershock Toronato here 6.2 liter and spinnignthe hell out of the 19 pitch Rev4 about 5500+ RPM according to the ever so accurate tach. Anyways which prop would be the best choice for the top end we wakeboard occasionally so i am not to concerned with bottom end just as much top as i can get while running about 4800 to 5000 RPM. I dont think with that motor i will have any problem puling wakeboarders.Well any input would be appreciated
