we are using a 2007 , 24 ft enzo, with full ballast, 1 400 lbs sac, each side of stern, switch blade up to 7. With the sideswipe engaged to blow exhaust out side of boat, say port side, the port has a crappy washed out wave. However when we switch the side swipe to the opposite side,the starboard side its sic. So both waves are great and clean with the exhaust blowing out the other side. I am stupid when it comes to hydrodynamics. can someone explain?
