we have a 2005 sea ray 220 open bow with a bravo 3.
and we put about 600 lbs in the bow, then 750 lbs under the back seat right in front of the engine.
and our wake is pretty dope.
the pic i just attached was the 600 in the bow, the 750, and 5 people in the boat moved around so the wake is clean on both sides.
this was 23 mph and at 65 feet.
edit-- we put a 750 lb sac just in the center ski locker just to see what would happen, and it made the boat next to impossible to keep straight, and even the slightest cut would cause the wake to get large amounts of white wash. it was bad in all ways.
i also forgot to mention, our boat needs more weight on the drivers side to get both sides of our wake to clean up. so the 750 lb sac we have in the back, is slid all the way over the the drivers side and filled up under the back seat. and it seems to do the trick. if you have any other questions. feel free to ask and ill try and help you out
