Drew,
Great write up. The mojo locker in the rear is huge, my1100 pops my locker on the xlv.
What's the directional valve for, wouldnt you have the ibs and the center locker full at the same time?

Right!! My kids the same way here lately. Had a two hour window the other day. To easy to put boat in and lace up but no, had to spend half our allotted time getting boat surf/trailer ready. Weirdos🏄
sent from my ipad2 via a wireless network which usually sucks
funny my kids really are into boarding and with the xlv , no additional weight needed at this time, wake plenty big...
I wish they wanted to surf more so, the DD could get some time in.
thanks for being so detailed and all the great pics...got our new mojo late last season and so far only boarding. Definitely plan to get into surfing this yr and looking at ballast upgrades now. My son works at a shop that can only get straightline and I have spent a good bit of time reading about the fly high bags and that seems like the way to go...did you also consider the L shaped bag to sit on the rear seats? Also, Mike at barefoot int. said that rather than the one bag system in the bow use 2 separate under each seat so you can just weight the side you are surfing on...
First Welcome, great to hear you have a Mojo.
I have been doing some testing on mine, and i dont want to share it in this thread due to not wanting to mess up Drews thread.
I personally have found some different set ups im messing with. I took some video yesterday and will have to get it uploaded.
Also as fore the Straightline bags, there is no problem using them. I used them in my LSV and i actually have the 900s in the rear of my Mojo right now, while i am waiting on the 1100 to arrive.
I will share, in my Mojo it wants a TON litterally of nose weight. I was getting a much nicer, cleaner, wave with 1500+lbs in my bow then just the 500 center and 650 IBS.
As for dividing up the weight in the bow, i have been thinking of running the 2 450 bags in my bow to weight the nose more but i personally dont want to weight only 1 side of the nose.
Look for a thread on my Mojo surfing experiences comming soon.
I had 3 objectives: good/great wave, no drilling holes in the boat & all hidden. So, I didn't consider the L shaped bag and I didn't/wouldn't consider splitting the front into a 2 bag system. I do wish the IBS was larger.
This is why im thinking of running my 2 450s in the nose, just daisey them together so they run off the single pump and drain still. Not sure if it will work but worth a try. I have no desire to only run 1 eighter.
With the IBS full i still have so much extra room in the bow LOL.
My goal is the same as yours Drew, i dont want a bag in my walkway, or a bag i have to manually fill eighter.
Maybe I'll give that a shot this weekend. I'm sure it will fill fine, but not sure about draining. I did get one of the cube bags with the handles on it to throw around and it helped but I hated throwing the pump over the side & having the kids bang it on the side pulling it in. If chaining them together works, I may do that to this cube and hide it in the space behind the observers seat.
What prop are you running?....thanks
Cant remember. Whatever the upgraded one is from the factory.
The recommended upgrade is the Acme 1235.
I sent a long note yesterday with questions and info, but it still hasn't posted, will retype here and if it pops up later, you'll know what happened... :-)
Picked up new Mojo two weekends ago. LOVE IT, but so far unable to get any sort of a 'surfable' wake using the factory ballast and wakeplate, no matter how we've configured it. So looking for suggestions. REALLY appreciate all the info posted here!! That said, I'm sort of miffed that a "surf boat" isn't surfable somewhat right out of the box...even just a recreational wave. I surfed last summer behind a stock MB B52 v23 last year (2,300lbs ridged self-filling ballast) and it had a pretty good wave with no aftermarket ballast and only 4 medium-sized people in the boat.
We have the 345 surf engine with the upgraded Acme prop option and so far I've learned the Mojo does like a lot of nose weight, but the stock 500 tank doesn't appear to be enough. We seem to get close to a surfable wake at 10.7mph with the front tank full, and back port bag (650lbs) full, and a couple of bodies on the port side. But can't create a wave that we can can actually surf. We are currently using a 2011 Hyperlite Broadcast board, which came highly recommended, so that shouldn't be a big problem. Thoughts? Would really appreciate any ideas.
I would HOPE I don't have to buy another $1500 in bags and manual pumps to get a surfable wave.
p.s. The Footers Edge dot com has really good info about configuring ballast. See their Ballast guide PDF.
Thanks!
Steve
Steve Congratz on the new Mojo, looking sharp man.
I am going to assume you have the 650 in the rear of the boat yes?
Out of the Box the Mojo will surf but you have to remember that out of the box this boat has to deal with a Factory Load rating, and this takes into account the ballast and PEOPLE so the Factory wont put a slamming 2500LBS system in this boat.
Although through my dealer i got to upgrade the rears to 1100 and add an IBS.
First lets start with whats your surfers weight?
Pic of the wave would be awesome to see if its dialed in correctly.
As for factory setup, to maximize what you have you will need to fill hard tank, fill port side rear, and prolly 30% on Starboard rear. This will add more weight in the back of the boar to make the wave pop up and push a little better.
Also tell me what you feel when you surf?
Does it feel like your constantly on the front of your board trying to speed up?
If so try more wake plate on the boat
Try moving your back foot slightly forward
Move your front foot near the front 8inches of the board
Slow the boat down by .2mph in increments
10.7 is pretty fast for a stock wave, the problem with a stock wave it will be shorter, and the pocket will be small and tight but its there.
Want to experiment before you invest in bags, take your starboard bag, fill it and toss it in the nose and watch how the wave changes, or you can also tell people to sit up there momentary.
MM, thanks for the super fast reply! Yes, we have the standard 650lb backs in each of the back lockers. We've played with varied fill amounts in the other bag (yes, it does help to have ~30-50% in the starboard bag), varied speeds from 9 up to 12, varied plate positions and can't seem to produce a wave that anyone can stay on...including experienced surfers (not world class boat surfers...just guys who have surfed other boats and beaches and have some knowledge).
If I replace the rear 650 bags with 1100 bags, will that get me something?
(btw, what is "IBS"?)
Thanks!
Steve
Also to note the Broadcast is a Slower heavier board, this is why its such a great beginner board. I personally havnt rode it but i have the Ride Board in my quiver and i cant surf it unless i remove the rear center fin to speed the board up.
Yes 1100 in the rear will help tremendously if your not running a lot of nose weight. It will make the wave steeper giving it more push or power but it wont help the pocket length.
IBS integrated bow sack for under your bow seats.
Personally i cant say for sure, as i haven't surfed my idea in my theory yet. Next time we go out <hopefully> this next week we are going to take the 1100 out of the rear and add the 650 back and weight the nose to 1500 and see how it surfs. With my visual testing the wave is much nicer with only a 650 in the rear and a heavy nose but like i said i haven't surfed it yet. If its a stellar set up ill be posting TONS of pics and video to prove this point, but as of right now i cant say its better at all.
Wow, 1500lbs in the nose...watch out for rollers coming at you when you're slowing down! :-)
What's the 411 on pumps? The stock ones seem to take quite a while to fill. If I change out the stern 650s for 1100s, It'll take a VERY long time to fill them. Is it advisable to put in a higher volume pump? Additional pumps?
I'll try taking off the middle fin on my Hyperlite Broadcast and see how that works. IS there a better "intermediate" board I should look at? And what size? I'm 6'5" 200lbs, and my wife is 5'5" 135lbs.
Surprising with 1500 up front i still have a good 2-3 feet of nose out of the water when she is approaching you at idle
Pumps will be fine
Fill time should be apx 1 minute per 100 lbs of ballast. 6-7minutes for the 650s and 10-12 minutes for the 1100s
That board is fine for what your doing, as in learning, there is another thread talking about boards to try out.
General rule of thumb, the lighter a board is the faster it is in the water, and the more expensive a board is the lighter and faster it is in the water.

Good link. Thanks!
Ok aftercmuch research order my IBS 650 will be in next week so we can work our surf wave......also have upgraded the rears to 1100 and just got another Acme 1235 to replace the one on the boat to send out and have a spare....will keep everyone updated on install and results......great page guys!
Hi guys - I am helping my bud get his new Mojo dialed and want to find out where is a good starting point. He wants a good wave but probably won't run as many bags as OP.
It sounds like 1100's in the rears and a bow sac might be a good start? Does the Mojo care if the weight is centered in the bow vs. all on one side?
Thanks!
1). Post pics
2). Order 1,100's from wakemakers. They are plug & play
3). Order IBS, bosworth Y,1" fixed Y and a some hose & clamps from wakemakers.
4). Install #2
5). Enjoy a few cold ones
6). Install #3

you need to ride more boards . . . . .
The shape and buoyancy are what make a board go faster. Fins also make a difference and quad fin or twin fin set up will offer more speed on a surf style board because there is no fin down the middle like a thruster that holds it back a little.
Flyboy (Jeff & James Walker) do a ton of prototyping of boards. Sometimes technical, but always entertaining read:

I will check that out but i have ridden more then a dozen different boards and almost all of them have been different styles of surf and my general finding is exactly how i put it. Some boards are heavy such as a couple IS board and they are fast but nothing is as fast as the Soul Craft i have and like i said a lighter board will be faster in the water because it too has less drag.Quote:

Also some, but not all boards that have 3 fins will be faster by removing the center fin.
On my Soul Craft its faster by removing the 2 smaller fins and also replacing the rear fins with slightly smaller ones makes it more maneuverable.
Also another consideration is Rider Weight, if your light or well under the boards maximum weight limit the board will of course be much faster then if your heavier and closer to the boards weight limit.
Fins make a big difference if the rider is heavier and sinking the board deeper in the water. In other words, different sized riders may feel different things from the same fin setups.
fins 101:
http://www.surfing-gear.net/surfboard-fins.html
A number of pros are now running up to 6 fins on surf style boards. The number of fins shouldn't impact the speed of the board, it's the size of the fins, specifically the base.
Purchased and installed all of above per drew's specs, complete with the bosworth directional Y and extra fitting filled with epoxy. All I can say is WOW WOW WOW!!!! We've been running the stock ballast with (1) 750 up front and (1) 750 on rear port seat while we waited for the order form WM. That wasn't bad but this is like a completely different boat. This is spot on the perfect setup for anyone with a mojo.
Not to mentioned if filled perfectly, fit perfectly, drained perfectly. With the check valves there wasn't a drop of water left in any of the bags.
I was able to do the complete mod in just under 2 hours thanks to this post.
Thank you Drew for doing all the leg work!
Anyone that has a mojo and likes to surf this is the best $$$ and time you could possibly spend.
Nice! Glad you're pleased with the results. I've been toying with the idea of switching to an Enzo sac, but having a hard time with that $400+ price tag.
As some have mentioned, I do sometimes have issues with the center tank fully draining. Some have tried different style check valves, I've just been popping off the IBS fill/drain line after its flat.
I've also found when it's just the family, a 150lb "brick" bag in the port corner is great. However, I also found out yesterday that I'm getting old and that trying to move that little sucker from one side to the other while the boat is pitching around isn't good for my back. I tweaked my freakin back so bad yesterday!
I find it highly illegal to weight and test a mojo on the south end of ones lake without the proper supervision from an elder forum member...:p
Can't wait to see the pictures
North end member:)
Happy Father's Day
South end wave:

Way back - still alot of push

Very nice!!!! Looks like that wave is dialed in good, now just have to show you some flat water spots on the lake.
Hello Wolfeman, your setup looks great and I'm planning to upgrade my stock gravity3 system on my Mojo (which is poor for surfing). I maybe do your setup but have some questions :
- the 370 tube sac is the 62" length ? looks too long to fit under the seat (it's the only 370 sac available now) if not, I just find an other one that fit.
- do you have the list of all the fitting and hose that you used? (sorry for that one...). I live in switzerland so it is not simple for me to order a single "missed fitting" have to wait 2 weeks and cost me 38$ of shipping for a 2$ item :-(
- the stock ballast are 3x 150lbs (4'30 of filling time) ? And it is not possible to upgrade the center ballast ?
Thank you very much
Way to take car of the Swiss. Don't mess with them or we'll be stuck with second rate chocolate. Plus they have all our secret money.
Hello, to understand, I draw the schematic of the setup. Could you tell me if I'm right ?
Thank you
