Need help for setting up the wake for boarding on a 2011 outback v. Right now I have 750's in the rear and then 400 in front locker. It is kinda lippy whith every thing full, seams like the wake rolls over. Riding at 65 ft and 21.5 mph. I can jump toe side and heel. I just want a big clean wake and would love to ride at 70 feet. Does the wake get better. Wife said this boat has to last 2 more years. Trying to learn flips and want a bigger tranny and tips?
