Mojo - Weight Distribution Advice

Hey all,

I got my 2019 Mojo through the breakin period this weekend. I got some surfing in and it was pretty awesome, just have to tune the wave a bit. I have the following setup:

1) Rear 1280 ExactFit Bags
2) 1200 upfront(with IBS)
3) 500 lbs of Lead

I am going to work this summer on fully understanding Autowake, but curious others experience on:

1) Are you running both bags 100% full?
2) Where do you put your lead?(IE - Under rear bags, under bow filler, midship, etc)
3) Wakeplate typical %
4) Surf Tab % (both port and starboard)
5) Are you draining bags and listing boat a little more?

Thanks all, just looking to fast track my knowledge on other's experience!

Nice, the mojo is a great boat, you're going to love it, we do! You're going to be putting almost all of that lead up front. Think of it this way, you added weight in the rear, but kept the front stock, it's going to need help, plus people almost never want to sit in the bow, they want to sit in the back, which only adds more weight there. I try to keep the wake plate as minimal as possible, but I usually do have it deployed just a bit, more for a beginner maybe almost half. I forget the surf plates but I believe 60 for regular wave, 65 for goofy, this is for flow 2.0, not sure if you have 3.0. I always list my rear bags a bit, that helps the wave a lot, but again, if you have 3.0, I assume that's needed less. I have bags under my mid seats, makes the wave even better. Good luck, have fun!

I have enzos plus center and ibs.

I run everything full. I sit 2-4 people surf side. And 2-4 up front. I’ll be be getting 600lbs lead for front and surf side when just wifey and I.

I think i just bought a new 19 Mojo, need to start sourcing bags ect. Boat comes with 3000lbs ballast with the IBS, how heavy is the IBS bag?

1) rear bags - 900 each; I upgraded to WM ExactFit 1280s that go underneath side seats...would recommend them as they fit really well.
2) Center is 700
3) IBS is 500

Sounds good, most likely grab 600 or 700 lbs of lead until i can get the exact fits delivered.

Funny what happens when u wake up Monday morning with a hangover from hell and no clue what you just did/purchased over the weekend! Well if it turns out to be a Mojo, feel comforted to know its a great boat. I love mine.:cool:

Like everyone else is saying. Add more weight. I wish I kept my 1100's and added extra weight in lead instead of Enzo's. The only draw back from Enzo's is they take up all your space in the middle seats. Its nice to have the storage for towel bags, coolers, snacks, etc.

Do you have any pics of the wave with the exact fit?

Not yet...this weekend was the first in the water and still getting it dialed. Give me till July to post some pics. What I will say is they really conform to the space well without putting crazy amounts of pressure.

I bought some cargo nets to mount above them in the side seats and rear lockers to allow for life jackets and ropes to hang above them...will post pics as it all comes together.

1) Are you running both bags 100% full? I have stock ballast and we have two 400s under the cabin seats on either side so its basically the same as your exact fit bags. When we want to do it right we fill everything 100%.
2) Where do you put your lead?We have 200 lbs of lead, 150 lbs mid ship starboard side under our 400 bag and 50 lbs mid ship port side under our 400 bag. The offset is for two reasons, to offset the battery weight and we all surf goofy in my crew
3) Wakeplate typical % We run the wake plate at 0% because we like the shorter taller wave shape
4) Surf Tab % (both port and starboard) for us goofy riders i think we set it at 60 or 65, i cannot remember exactly
5) Are you draining bags and listing boat a little more? No but we do try to move the majority of the passengers to the surf side

Thanks all, just looking to fast track my knowledge on other's experience!

We have a 2017 Mojo and I put our set up in red. We have found that when surfing, we can usually do really good without auto wake. I find auto wake most useful for wakeboarding

Do you mind sharing the link to the cargo nets? I need to do the same to my 18 Mojo.

Side Seats - I went with 42" ones

I have the 2019 Mojo and the Wakemaker's BagBuster upgrade. I also run 150 lbs of weight that I move around (mostly up front). I find the lead weight really helps the AutoWake when the boat is lightly loaded because it wants to dump water from the back to achieve pitch. I have considered adding more to help with roll as well because with 3-4 people in the boat AutoWake wants to dump too much water from the non-surf side. If I only have 3 people in the boat I frequently turn off AutoWake.

My wave is very surfable. I'm a big guy and with a fast board i can easily surf the front and rear pocket on the wave. I find many people complain about their wave when the real problem is their technique. Technique + displacement = happy surfer!

I am slowly playing with my Mojo and last night it had the best wave to date with ~30 hours on the boat this summer. Here was my setup:

**Disclaimer - I like a steeper wave for surf style

1) 1280 rears - Both of them full(Wakemakers ExactFit)
2) 500 lbs of lead (250 on rear seat corner, 250 on floor near rear seat)
3) Front @ 80%(I think I coulda ran it 100%)
4) Driver +2 adults surf side(one on swim deck, one on rear seat)
5) 2 x 50 lb kids wherever they felt like sitting ;)
6) Wake plate at 15-25

The length and push on the wave was awesome...I think getting the front to full would have lengthened the wave even more.

I am only 180lbs but the curl was hitting my thigh and still tons of push off the curl. We had a 220 lbs guy getting back really far and still tons of push. RPMs were ~3500 with the OJ 15x13 Prop.

Really impressed with the push and length I am getting off of it once I am figuring things out!

Try running just a bit faster with wake plate at or near zero.

Any update on tweaking your wave?

Currently, I run enzos full, center and IBS full, 200 lead midship port side (offsets driver), 150 lead bow. Tabs are port 60, starboard 80, wake plate 20. Attachment 28889

I had enzo's on my Mojo also, no lead though. You're the second person I hear adds 200lbs port side to offset the driver weight. I like that idea, i'm gonna try that next. I am a firm believer that you weigh the boat evenly side to side and let the surf tabs do their job.
I also see you added lead to the bow.
I posted this recently, but in case you did not see it, this was my experience with the IBS. It fills as overflow from the center tank. As center tank fills it moves its air into the IBS. The IBS fills with air first, once the water overflows from center tank it moves into IBS.
Problem is the drain line is located at the bottom of the IBS, left side. As water flows in and reaches above the level of the drain, air is locked in you will see the overflow drain expel water and the IBS looks full and tight, but its 80% air. You have the open the top vent plug, let all air out and replace and then it'll fill with water. You loose a lot of front weight due to this. Solution would be to have put the fill overflow drain at the top of the bag like the rear bags are.
Maybe this was just my boat. If its not, I would think this occurs with all IBS's.
Can u check and see if you have the same issue?. I'd be curious to know. I should try to check on my supra but haven't figured out how to remove the flooring easily.

I will definitely check next time we go out.

If remember correctly my bag has 5 ports. Right bottom is fill, left bottom is drain, top middle is overflow, the other 2 are on left and right on top with plugs.

Thanks for the heads up.

OK, my IBS did not have a top middle drain. Like yours I had left and right bottom for fill and drain. Having a drain on top would solve the problem. Interesting, was that a design update? Anyone else with a '15 Mojo that does not have the top middle drain on their IBS?

No idea if it was a model year change on the bag or not. It a fat sac.

I have the factory IBS on my 2016 Mojo and it has the top center overflow port.

I was air free today. All bags filled full of water. Rearranging the lead some. Put 240lbs in bow and 240lbs port side mid ship. Wake plate zero and surf tab 60. Attachment 28970

Update.

All bags and tanks full= 4100lbs water
Lead weight= 480lbs
10 riders= 1500+-lbs

The mojo loves weight. The wave was massive and very long and had push throughout the entire wave. The Raptor 400 had no trouble with OJ945 getting up and going. RPM around 3200-3800 depending on speed. Wake plate 0, Port side 90, and Starboard side 55. Speed was 10.5-11.5. I’m super impressed. Attachment 28986
