I am a beginnning and am in the process of buying my first wakeboard boat. The dealer said it is a great beginner boat because it has the power and throws a good quality wake that isn't real big. My question is as I advance what can I do to make the wake bigger. I have seen adjustable plates on the stern inbetween the exhaust pipes and don't know if this is good for adjusting the size of the wake. My boat will not have that but can it be added?
