it looks like it's ballast upgrade season, with so many posts.
I thought i'd share my experience, since I was a bit scared to do it, but everything well.
i picked up the kit from wakermakers.com (http://www.wakemakers.com/supra-moom...m-upgrade.html) and watched carefully the video on how to drill thru the hull:
thru hull fittings location:
Pump location: the middle pump is higher than 2 others to allow for room for the hoses.
I installed a Y valve to control filling the center/front ballast and the 400 bag under the seat (on the left side, mostly regular surfers on my boat)
I didn't change the 3/4 hose going to the center/front bag that was too much work... but i did add a vent at the front of the bag, hooked to original drain.
I found it very useful to use a pvc pipe cutter like this http://www.homedepot.com/p/t/2023518...7#.UX9IhN7n_IU to cut the hoses.
the 750 bags now fill up in about 5-6 minutes, which is about 1/3 of the time than before.
that was a very fun project!
It's really worth it, i don't regret at all.
