we put a 750 sac in the rear of our I/o and a 650 bow sac in the front about 2/3 ful on the front one. it cleans the wake up alot, firms it up, and makes it just a little bit taller. it only looks bigger by a little. but when you hit it. it boots you
700 in the locker, 350 in the bow, 350 in the walkway, (2) 85lb bags to counter white wash. Cleans up really well and is tall and firms it quite a bit. You can tell a difference.
we put 1500 lbs in our bow today. it was so rampy it was rediculous. we had 650 in the bow, then 3 people in the boat. and the wake was killer. it was supper steep at the top, ill post a pic when we upload from the camera
this was with 650 lbs in the bow, and 3 people in the boat. one of which is 10 years old. this has been the best set up for us. it helps a ton. cleans it up, makes it taller. this a 22 foot sea ray BTW
DO IT!!! Fat sacs will only make the wake better (depending on where in the boat you put them). Definately sac your boat out! Every boat can use some weight gain!
