In general, wakeboard boats perform best with larger-diameter, lower-pitch props, which produce more push out of the hole and more consistent speed, especially when heavily weighted. In addition to increased performance, a wake-specific prop will also yield better fuel economy when you're wakeboarding and wakesurfing. There are tradeoffs, of course. At cruising speeds, that same larger-diameter, lower-pitch boat prop will burn more fuel. Top-end speed also decreases as you go down in pitch, which won't appeal to riders who have to run across large lakes to find good water.
