X7 Ballast Question

Hi all,

Sorry, I just realized that I replied to a very old tread so posting my question again.

I have a 2008 X7 with LY6 and my kids are looking for a bigger wake for wakeboarding. I was thinking of going with 2 x 750 fat sacs each side of the engine box in addition to the standard bag under the rear seat. Wakemakers have suggested that I could go with 2 x 1100 fat sacs, what are peoples thoughts on this? Seems like a lot of weight but I guess they don't need to be filled completely.


Regards

Paul

I know a guy who put more than that in his 197, the wake was about X2 size. Also, you may want to try a little weight up front 3-400lbs, or not so much as to dip the bow under through rollers. Like you say, you don't have to fill them all the way up: dial it in to your preferences.

You should measure the space next to your motor box. Too wide of a sac and it will put a lot of pressure on the motor box pushing it against your exhaust manifolds.

400# is 16"X42"
750# is 20"X50"
1100# is 24"X50"

I believe you're wider but in my 85 the 750's rub and can't be filled all the way anyhow. The boat actually handles fairly well with the bags located there though.

By my measurements the 750's would just fit and even be compressed a bit so it may be a waste going with the 1100's which are 4 inches wider and higher. Wavemakers have a sale on at the moment so I need to make up my mind ASAP...

Sorry, doesn't apply to an X7

Regarding the too wide of a sac, if this is a concern I know some folks bolt in a steel bar to reenforce the engine panel. I think some people also extend the "U" shaped brace along the floor for better structure.

I think some people have actually melted the engine panel since it was pressing against the exhaust manifolds. I'll be doing this mod to my x-star as i install the PWT ballast system... next spring

Side sacs will help with wake size and balance but I find some bow weight is the final piece.

So much weight in the rear will tend to drag the stern and make coming on plane more difficult, especially with a load of fuel and 3 across the back.
Bow weight will "firm/fatten" the wake.
