98 Air Nautique weighing

Any suggestions on what bags to use and placement?

Right now I just have the stock ballast and I'm not even sure how much weight those hold.

Any help is much appreciated!

Depends, for a slightly better wake, put a flyhigh tube sac over the factory tanks in the rear and another in the ski locker. Add some lead in nooks and crannies.

Better than that, remove factory ballast, put 2 gravity games sacs in rear compartment and seat sac in ski locker plus lead in nooks and crannies. This how my 2000 Air is set up and all ballast is hidden. If you want a bigger wake than this, you are going to have sacs on seats or in walkways. I would say my wake is pretty good, but with only a driver, it could be better. Your factory tanks hold 400-450 lbs.

I have ran a full fat sac in the rear with 5 people in the boat and that was nice. Otherwise I have ran 2 400lb side sacs next to the motor biased towards the rear and that worked out well.
