Wakemakers Gravity 3 Ballast upgrade - 2008 XLV gg

[MJHSupra]

So you think its a good DIY project? Agreed, putting them in the correct spots is the most important part.

Yes, but my comments are based on the number of people that have done this in the past. Lots of DIY peeps. There should be posts or pics to help you with the two planning items:

1) Where to drill the holes
2) Where to mount the pumps

My Supra allowed me to drill the holes around the V-Drive area. Spaced apart. Thus the access was easy when I lifted out the back cushion seat. If I recall, there were 2 holes on each side of the V-Drive - one at the front area and one towards the middle. The front holes were the raw water and orig ballast hole.

The other item on the original ballast hole, I used a cutting wheel to cut off the brass scupper. Thus it will NOT force water into the system when running down the lake. Not sure if you have one on your hull.
