I am looking to increase my ballast, mainly for surfing. I currently have 650 in the center and 400 in the rears. I believe that is stock but I'm not sure, I bought used. I believe that 750s will work in the rear but not sure about the center. I have hear yes and no to 1100.


Please help!!!!

I believe the 1100 will work in the '07. I have an '06 21V and the 1100 fits nicely in the center.

I am pretty sure that the '06 and '07 are fundamentally the same. I think the only thing different is the dash. I was just looking for conformation before ordering.

Yeah the 1100 lb sac will fit fine and is a must. If you do that just take your 650 out of the center and order one more 650 and put them both in the rears. Your boat likes lots of weight up front and this will help move the weight forward a bit since the 650's are longer sacs. Also allows you to store vests on top of your bags... you will be running 2300-2400 lbs in no time and you will love it....

I was thinking the same thing Any clue as to where I can pick up a 650 sac that is the same as the one I already have. I ordered an 1100 gravity games sac from wakemakers.com, but I can't find a 650 (16x16x70) like the one I have now.

Any Supra dealer should be able to get one. I would think Wakemakers could get one too. Not sure why they could not. Have you checked with them?
