please help with prop selection for wakeboarding

I just purchased a 2004 tahoe Q-4 ski and fish, with a wakeboard tower. it has the mercruiser 4.3l 190hp engine. the boat is very difficult to get to plane when pulling a wakeboarder, so im wondering if changing the prop would do the trick? what is a good recommended prop for faster plaining, and holding the lower speeds. I am not concerned with loosing top end at all. I want the best pitch prop for the quickest plane. I currently have just a stock 3 blade, but dont know the pitch. would a 4 or even 5 blade prop be better for low end? any recommended brands, and pitch? Thank you
