how to increase wake height?

[tayfun]

Hello,

I have a 6 meter (20' boat) with a 115 outboard jhonson behind it and a home made wakeboard tower designed by me. I have problem with the wakes the boat makes. It is only little over a foot high and I am wondering if there is a way to increase the size of it? I had heard stg about a plate attached right above the prop? And someone mentioned about phat sacks. What is a phat sack really? Any bit of information would be highly apprecited

Add weight..a fat sac is a bladder you fill with water to weight the boat down. The other thing you are talking about is a wedge which I thikn is pretty risky (transom problems) you can get sacs at a lot of places:
