Couple things, I HAVE played with the surf tabs on the supra and moombas we have been on, but the defaults on those, i have found are good and you should prob leave alone. Especially IMO you shouldn't use them to try to "adjust" the wave, adjust the wave with pitch (steep, length, push) and not the surf tabs IMO. You get all of the push with the tabs deployed to default, and if you bring that up some, the wave may be a shape you like, but it won't be as powerful.
As far as the lead, first, watch this video I did:
https://youtu.be/fRX6v9QpycI
It gives great principals on how to work this out on your boat.
On the mojo, I think it least half of the 1000 lbs is up front, I will count all bags on our next outing. But its basically a simple principle, find the best pitch and roll for your wave that you want, and then place the lead so that you will be at 100/100/100 and you are surfing at that pitch/roll, and your wakeplate is NOT higher than 25. I prefer ZERO on goofy on the mojo. So there is no, "put the weight exactly here" answer. It depends where everyone is sitting for instance. When its just my wife and daughter, we have it setup perfectly. I have AW on, and sometimes one side may go down to 90, that's it. But if I bring some people on the boat, and they all sit in the back, I may move some lead up front, or tell someone to sit up there, or my pitch will be at 11.5, and it won't be that great, get it?

Ragboy's video on where does the lead go was a game changer for us. I have a new SL and used his video on the 18 SL as a guideline for pitch, roll ,speed and lead placement. Results were not good. Went back and watched the above video and ended up with a very different lead placement to achieve pitch and roll. I had no lead in the rear, 250 per side under mid benches near the tower and 300 in the bow. In the end like Ragboy says, you need to consider the passenger loads. Our family is 'light' and the difference in family weight shifted Ragboy's rear locker lead to the bow in our configuration to get the same results. Use the pitch and roll baselines, move lead to achieve those numbers with stock ballast near 100% in all and then tweak the wave as needed. Life is Good when the wave is killer!

Thanks. I have watched your video a couple times and I believe I have that down. I had been playing with the surf tabs just to see what difference they would make, and now I don't remember what the factory settings were. I am guessing 60 for regular surfing and 70 for goofy?
Going out again tomorrow, I will drop the wake plate down to 10, and move a little lead from the bow to the stern to get my 9 pitch up to 10. as well as moving some from port to starboard to get me closer to -1 vs -1.5
Thanks for all the help. I think with these couple tweaks it will be even better than last weekend.2021 Mojo

Your welcome, I would love to know what you think if you like the pitch up around 10.

Welcome to the forum! Glad to have ya! Still would love to come up and ride with you guys or stop in by our house to take mine out. I see you have kinda changed on the %50 wake plate neutral thinking. What led to that? Just more dialing in? Always great to read and watch your thoughts.

Yes sir!
First of all, it's an honor to have you on here!!
Secondly, thanks for all you do and the videos.
But yes, I noticed last time out the pitch at more around 10 is FANTASTIC!! It's funny because it was so good that when I got back from the lake I was going to DM you and ask what you are thought about it. I assumed you would say it was too high.. LOL.
As mentioned, got the wave fixed up and dialed in, and I am happy to report it is ahhhmmaaazingg. Seriously one of (if not the) best waves I've ever ridden. Beautiful shape / lip and very very clean. I sent you pictures on FB of the wave and everyone airing it out now. Great push front to back... can't wait to get even more lead.
One thing I will say though... is last time out, everything was great.. shut the boat off, switched out riders.. (changed NOTHINg).. got going again and the wave was complete trash.. we spent the better part of an hour going through Everything all over again... only then I remembered that when I first got my max, if you didn't allow it to "boot up" though the entire Moomba boot up screen, the plates would be all "out of synch".... so...
Shut it back off (even put battery to off).. rebooted, allowing it to fully restart... and voila!! We had a bad ass clean wave again! Not sure what it is but the plates can get out of "synch"... weird!
So the advice for your boat is now the same as your computer "when in doubt reboot"... hope that helps someone. Wondering if we had the same issue first time out and just didn't realize it?
Thirdly - not sure what the experience has been here, but in the Facebook Moomba owners page .. LOTS of new 2021 Mojos are having alternators die? Most less than 20-40 hours in... Maybe just a bad batch.. but something to definitely keep an eye on, pay attention to.
Thanks again for everything!

Love seeing all this discussion on weight and wave setup! I have a new 2021 SL450 (picked it up about three weeks ago). I have 1000 lbs of lead and we've usually had a moderate crew of 5-7 people. I want to surf at about 11.3 or 11.4 but the boat STRUGGLES to get there. Sometimes it simply can't do it. I've been slowly moving more weight toward the bow to the point that there's only 100 lbs in each rear locker. That has helped some, but it's still a struggle. I've had to start adding center plate to help the boat reach speed, but of course this is counter-productive for maximum displacement and the best wave. Is this normal? I really didn't realize that the power margin would be so slim for surfing.
