How can i find out how much my factory ballast weigh? I have a 2003 supra ssv. Not sure the size of the ffront bag but i blew up the rear bags and measured them and they are 14x14x30. I need to know the weight they will hold so I can sale them. I have my new 750lber's ordered. Thanks

This was posted before but it does not cover my sac. My sac is a regular fly high fat sac from my 2003 ssv. It was made specific then for supra/moomba.

Here are the sizes he has available in the factory seconds; you'll have to email him directly to get the prices;

> 12 X 12 X 48

> 12 X 6 X 150

> 14 X 14 X 64

> 8 X 18 X 66

> 10 X 16 X 70

> 8 X 15 X 62

> 10 X 26 X 62

> 16 X 16 X 30

> 12 X 12 X 48

> 22 X 18 X 30

> 10 X 16 X 62

> 20 X 10 X 56

> 18 X 8 X 48

> 12 X 20 X 40

> 18 X 7 X 37

> 16 X 16 X 70

> 12 X 12 X 30

Because I'm a dork I calculated the (rough) weight of each size. Keep in mind this is just the weight of the water for the stated dimensions, not including the weight of the bag, etc...

Size Approx Weight

12 x 12 x 48 = 250

12 x 6 x 150 = 390

14 x 14 x 64 = 453

8 x 18 x 66 = 343

10 x 16 x 70 = 405

8 x 15 x 62 = 269

10 x 26 x 62 = 582

16 x 16 x 30 = 277

12 x 12 x 48 = 250

22 x 18 x 30 = 429

10 x 16 x 62 = 358

20 x 10 x 56 = 405

18 x 8 x 48 = 250

12 x 20 x 40 = 347

18 x 7 x 37 = 168

16 x 16 x 70 = 647

12 x 12 x 30 = 156

Capacities are easy to calculate, just multiply the dimensions in inches to get cubic inches, then divide by 1,728 to convert to cubic feet, and then finally multiple by 62.4 to convert to pounds of water.

So a 14x14x30 bag would be: 14x14x30 = 5,880 in^3/1728 = 3.4 ft^3*62.4=212.3lbs.

Does that mean the w707's are really on 722lbs. What makes them sale as 750. Is that because they expand some?

You can multiply your dimensions and divide by 27 1/2 and get real close.

Could have sworn it was 12.6 but the alternator puts out 14.2?

shoud I sale the bags as 212lbs or just say 225. 225 sounds better since it is not an off the wall number. What do you think? I know when i fill them they are actually larger then the mentioned dimensions.

When will you and the guys from the forum be having another get together for wake surfing? I have only tried my new board one time and didnt really let go of the rope. I was really to close to the boat. I dont think i had the boat weighted right according to some postings and you tube videos.

Ed, I had the 13th down as the date although I'm having relatives in town and probably can't make it. Guess the hydrocodone is working its magic.

As soon as Stacy told me I put it on the calendar for the 13th. But then my cousin called. He'd headed down from IL to get his Dad's old jet boat from my Dad in Clearwater. He'll be coming thru Tally on Fri-Sat. So I guess I'm out.
