Adding ballast to 2020 SA/SL/SE Etc

[SONIC]

So I'm now spoiled and am no longer happy with my wave when it's just the wife and I.
Don't get me wrong it's good but we usually have 5-8 people on board and the extra weight makes a ton of difference.
I find my self annoyed when it's just us that the wave isn't where I want it.

So with that said has anyone plumbed in extra ballast on a new Supra with subfloor with g6?
I'm thinking of putting a wye in the vent line with a ball valve so I can close it off. When there's no one else in the boat I'll open it up and hit the manual fill to get it full.

We tow to and from the lake and I don't want to load and unload more lead (I have 600lbs already).

Thoughts?

If it were me, I would add a 200-250# on each side under the midship seats, should be enough room.

Something like these

That would get you to 4000# water ballast to match what the new 22SL will have from factory

That's what I was thinking, or go full send and enzo the whole rear locker and midship seats :D

The last thing the Gen3 SA needs is more stern weight. Enzos would put all the added weight in rear lockers.

Having just slammed my Gen 3 near 11600#, you would never need those full enzos.

Need is relative :)

To each their own but the biggest and best wave I have had was with 12 people (full grown people lol), none of them in the front of the boat.
~10 degrees of bow rise and as deep as you can get the ass end will give the biggest pushiest wave in my experience.

Fair enough, at 11600, I had nobody in the bow, was 9.6-9.8 ish.

Motor was working for sure. I don’t think I would want to run her that hard every time out.

Yeah its totally overkill and I was mostly joking but hey I can dream right?

I've only been that loaded once (It's a pain when the boat is so full, great for surfing but sucks for everything else) and when I got on the wave I just smiled and said "now this is the wave I paid for" lol

It was massive, but hard to turn a lot going on no doubt.

I am pretty sure Dakota4ce did this in his SL when he had it. He added bags in the rear lockers that were plumbed into the bags below the floor.

Few people on social media did this on their SL.

Wakemakers sells a mid-ship bag that fits under the seats.

Plumbed a line from one of the the original ballast lines using a Y-Fitting.

Added a shutoff valve to the new bag on each side. Gives the option of using/not using.

Vented a Y-Fitting for the new vent from the existing vent line. Some add check-valves before the ballast sensor.

Some still run 100-150#s of lead on each side in the surf board locker corners.

The bags give you appx 800#s of add’l water weight that can be emptied.

Having just done something comparable to this, I'll add a few extra points that I've learned/seen first-hand in the last 2 weeks:

1) 9 degree pitch brings the rpms waaaay down. I was at 4500 rpm, w/6700 lbs ballast. 4800-5000 with 10 degree.

2) You have to reset/recalibrate the ballast timers. This gets somewhat more complicated because I found I filled faster when I wasn't in motion vs. when I was moving, say 5mph. This is important because when you're adding more ballast, you're running those G6 pumps much longer and you need to be at 2000 rpm (in my opinion) to keep that alternator happy. Can do it standing still if you're in neutral but then you're going to have some fumes, alternately, you fill slower while you're underway. I'd suggest trying to keep it consistent and only use one method so you can get your timers dialed in for perfect cutoff.

3) I still don't know if resetting the ballast timers is done by pressing "reset" when they're empty, or if you press "empty" when they're empty and "full" when they're full. What's the purpose of reset if you have the other buttons? Still experimenting with it at this point.

4) Since I added my extra ballast, the amplitude indicator is not really working correctly. There was a few days where it was showing max potential and max actual but this last week it's reset itself or something....I don't think you really need it per se but that's what happened to me.

5) Wakeplate setpoint doesn't stay where I set.

6) Swapping surf right/left sometimes needs you to shut-off engine to get the flow3 plates to properly reset. Definitely easy to see because the face of the wave will be terrible.

7) Saw some posts on it but I haven't had much trouble with turning while heavily weighted. When you have a goofy rider, you always power turn to port (after they fall off wave). Regular rider is opposite.

8) For myself, once I got everything working correctly for running heavily weighted, I don't think I could ever go back to stock or stock +1000.

I plumbed these under my midships seats. 60x20x8. Happy with the results so far.

Agree. They are a perfect size and still fit under the seats.
