2016 Mojo Surf Setup with Upgraded Rear Ballast

[matchew34]

I've seen a few threads about a lack of push from the 2016 Mojo and I have some questions from those who have tried similar setups.

We upgraded to 1100's in the back lockers completely full with completely full front/IBS. Wake plate up and 2 adult males on surf side. Typical water depth between 15-37 feet. 10.5 miles/hr

I've found that with this setup, I can get pretty good wave size and push on the port surf side, but the starboard side only gives sufficient push when you're surfing super close to the boat. If you get anymore than 6 feet behind the boat, it loses all push and you fall out the back.

We've tried adjusting the surf plate, wake plate, and ballast in the rear non surf side but still can't get the wave to lengthen with any push. We've even messed with the front ballast as well. With a total of water ballast weight of 3200 lbs, I feel like we should be getting a better wave.

Has anyone tried converting the 650 lb bags they took out after upgrading and adding them to surf side with any luck?

Attached is a pic of my starboard wave. 10.8mph, plate 100% up, tab @ 100% for starboard, 65% for port. You can piggy back the stock 650s under the seats and just accept that they won't fit well and can't fill all the way. I added 400s under the seats in addition to 1100s in the rear lockers. Makes a big difference when ridding with a small crew. Only two people in the boat when the pic was taken.

I also run 1100 in the rear. Rear, IBS and center full. For the goofy wake i have the following setup: Wakeplate all the way up, tab 100% for starboard surfing and 60-70% for portside surfing. I place 2 people on surfside i get great push and pretty good length. The only trouble i have is that the wave washes out from time to time. Don't know yet how to fix that. Starboardwave is easy to dial in. Everything full wakeplate at 50%. About 10 mph for both sides.

2016 surf edition moomba- bought it this summer as I assumed the surf issues I was reading about was "rider error"- we had it out each weekend- stock 2500 lbs- spent endless hours trying to dial in, but by end of summer it was the kids/ladies surf boat while the guys used my neighbors wakesetter (also stock). Even with added lead and 1000lb fat sack on the back bench, we called it a 4" wave (need a board 4" longer than we normally ride). My kids are young, my wife thin, so the mojo will work for a few years- but I regret the purchase- I'm 210lbs and am used to a 4'9" board, I need a 5'+ to ride the mojo mid wave! Tricks are out of the question, and endless pumping isn't why I surf!

So all your bags are still factory? What settings have provided the best wave? I have 200 pound rookies surfing mine. Maybe we can help so you can enjoy the nice boat you bought. Also, have you checked speed against gps? Mine was off 2mph.

I agree to check the speed and you absolutely need to put 1100s in the rears as the stock don't even cut it for the craz. Every foot backwards of those rear seats is going to dramatically add to the ramp and push to your wave. And even try and dump some of the front bag. I wouldn't quit on it just yet but I will say you def need more weight better distributed.

Why does the mojo surf wave seem so illusive? It seems some guys have it dialed and some guys are totally fed up with trying. The thing is built for surfing, it shouldn't be this difficult. I mean, it should at least be surfable from factory. Makes me think there could be some kind of issue with the way the tabs are mounted on a certain batch of boats. Maybe I'm grasping at straws here, but I feel like someone from moomba should step in with some assistance. Sure seems like there are quite a few unhappy mojo customers.

OP let's see a wave pic!

I wonder how many moomba owners that don't even visit this forum think that their stock wave is the best it's going to get lol.

Bag that shit already & stop complaining. 1100 rears and 375 under port seat. GPS your speed and get the surf tabs around 60-65%. Boom Boom [emoji631]

For the kids, we fill up the whole ballast, tabs full and plate 75%. I haven't checked the speedo, but will for sure. We are +/- 10 mph a half. For the kids/wife it's fine. When I ride with the family I use the trusty 5'2" O'Brien Haze, I only put 50% in the front and 80% starboard ballasts, but 100% on the plate to get consistent push- leaving me unfortunately dang close to the boat if I just want to relax vs thrash/pump.

I will upgrade the back bags to 1100s (are there bigger options that fit?) and check the speedo. I saw that the stock bags don't fit under the seats cleanly, but I could manipulate the fill % to make them work.

Sadly, for a $70k "surf" boat to need aftermarket, rigged under seat ballast and 4000lbs to be reliably usable is an epic fail. My friend has a 2004 Nautique that he surfs with less weight and drama. Regrets? I have a $70k one.

What do you mean by tabs full? Are you surfing regular or goofy? I don't have rigged under seat ballast or 4k lbs and I can surf without any issue. Same with everyone that has been on the boat. Bigger than 1100s isn't going to fit and it's not necessary.

Very few boats come from the factory with an epic wave. Even the 160K boats need tweaking and additional weight. Mojo has a fantastic surf wave. Take a deep breath, listen to what the others on this forum are telling you and go enjoy your boat. I can assure you once it's dialed in your friend with the antique Nautique will surfing your boat not his.

Go look at overall boat weight for the manufacturers you mentioned and you will see that mojo simply needs more weight. Mojo is about 2k pounds light compared to g23 and factory ballast is 2,900 compared to mojo 2,500. That's a huge difference (2,400 pounds). I have friends with malibu's they all need more bow weight which makes seats not useable so there goes family boat.
It's already been said but you can add a lot of ballast and be less than 130k for g23. This is just a silly comparison.

This also sounds like a dealer fail to me. Did you get a test drive? Did you ride it? Did they have settings known to work? Moomba does need to know their dealers could help this situation out a bunch at point of sale.

We attend a few surf competitions throughout the year and often compete behind boats that cost quite a bit more than your Mojo and they all require additional weight beyond what comes out of the factory.

.

Get a different board too., should be able to speed up to 11.2 and flatten plate a bit to get more space. If you get the he 1100s you'll need bow weight of 650 , if not 750s should do the trick to get you surfing at a fair distance.

Regular wave, 2 people in the boat. Can't get bent out of shape for needing more ballast, the new centurion boats come stock with 5100lbs.! Think about your boat's total weight with ballast, gas, gear, people,etc. The mojo needs at least 8,000lbs. min to have a good wave and more is always better. Most days with crew we ride in the 9-10k range. Compare that to the stock centurion at 10k+ from the factory and you can see why so much weight is required.

Thanks all for the intel- spoke with the dealer and they are installing the 1100s- they felt stock bow/mid was adequate with the 1100s. I also got the dealer to commit to getting a rep out to my lake once all is installed- will update once it's all completed- in the spring!

Anyone tried dropping in by jumping off the swim deck while in motion? I've tried it behind my craz a few times. Being so low in the wave truly makes you appreciate the size of these waves and the amount of water our boats displace. The wave is literally chest height from down there. Sorry to get off topic, but that mojo wave brings back good summertime memories.

I've played with doing this but the closest I have been has been from jumping off the upper deck. I can't get high enough from the swim deck to position the board. I've gotten the board under but my dumb ass can't figure out what to do after that [emoji12]

I have to confess that in order to make the best "looking" wave, we turned the boat away from the surf side. The slight away turn makes it steeper and curl harder but I typically don't ride it like that.

I have tried it a few times with zero success. It's so awkward jumping back into a wave coming at you. It sounds simple until you stand on the swim platform and try it. Maybe it would work if I weighed less but I think I use that excuse too much when surfing.

it's called an acid drop. my daughter does it all the time, especially in early Spring & Fall when she doesn't want to be in the cooler water too much. I probably have a few vids of her doing it. Key is to elevate enough to have time to get the board under your feet and you have to immediately lean forward & pump into the wave or you will just fall out the back. The cold water was motivation for her to learn quickly.

Ill second all of these issues. Upgraded to 1100's for 2017 and going to gps my speedo. 310lbs at 8.7 mph riding my dart 5'6 was all I could get with 750 rears. Wife and kids were fine, slim and trim. We shall see.

Not that u don't have to be careful but our best curl on 2015 mondo was upgrade to 2015 autoflow 2.0 plates. Custom 3600lbs 8 meat head muscle freaks and 3 fitness gals most likely comming up on 2k of bodies. Proper correctly and on glass a killer curl. Never do this on the new helix due to bow design...all the talk about 50 percent weight here...70 percent port or starboard is false. Displacement ...displacement...displacement. ...all plates at 55 to 60 percent.

If your not fully filling is and adjusting the trim tabs you are cheating yourself.

Freeboard is your friend!

Think what that m235 malibu can take! Freeboard dwarfs most everything out there

[Fat-chance]

I have a 2015 Mojo and I have found the following to produce the best surf wave for us. We have the surf edition with the bow bag and I've upgrade to 1100lb sacks in the rear lockers. I also upgraded the surf plates to the larger version 2.0. I fill rear locker bags and everything upfront completely full. I took the stock rear locker bags and placed them under the rear seats. Last year I used the Tsunami pump to manually fill the bags under the rear seats. I found that filling the surf side and leaving the non surf side bag empty produced the best wave. We mostly surf on the port side and set surf tab at 65%.
We found the paddlewheel was about 2 MPH off at surf speeds, based on GPS readings.
I am about to pull the trigger on getting the bags under the seats plumbed in.

I really like this comparison, my questions is: I have a 16 craz with the factory 2500 ballast and I am planning on adding more ballast (fly high Enzo 1450#) my concern is when is "too much" weight for safety? The factory recommendations with the factory ballasts is somewhere around 2600# between people and gear. If I add an additional 900# I still feel we will be safe for our usual group but again, when is too much weight? https://uploads.tapatalk-cdn.com/20170212/5b8c655323a4bdba6dc3b0cc0634b8de.jpg

I have never been floating in a craz but I have had my mojo with 4200lbs of ballast and a crew of 14. Never felt unsafe but never was able to get on plane without dropping ballast, even with an upgraded prop. With an evenly weighted boat, you can handle much more than twice the weight of the old listed setups. We used to list my buddies old Supra till we sunk the rub rail. That setup felt unsafe because it we so tippy when on plane plus the drop nose of the old Supra design was venerable to spearing waves for the inexperienced driver.

I regularly run 4200 lbs of ballast in my craz. I would say it's not even remotely close to the point of making me uncomfortable. It was my girlfriends first year driving a boat, let alone a slammed wake boat, and she never felt like it was unsafe.That boat has a ton of freeboard. My setup would be very similar to the equivalent of enzo sacs. Have you measured the lockers to see how well those bags will fit? I have talked to another guy running the 1450 enzo's in a craz and he said they are a big improvement over 1100's

Yep, they seem like they will fit perfectly. My plan was to get the 1450s and use the 2 factory ballasts to move around the boat to fine tune so that would be 4400# total. Do you have a picture of your wave with your setup?

I do have a few good pics, but not having the greatest time finding them. The one pic is the goofy wave in about 12' of water. Not riding the back of the wave by any means, but you can see I'm part way up the wave and it's roughly waist high. The other is a pic of the boat at rest with 3700 ish lbs of ballast and a couple passengers. As you can see the boat can handle big weight.

So the 1450's are like another 1000lbs over the 'max surf package' on the Craz. Doesn't seem crazy, but aren't you needing to add bow weight to keep the ratio similar?

Sorry, I thought that was just assumed that more bow weight was needed. I run an additional 300 on top of the 500 ibs, so 800 in the nose. I've tried 1100 total in the nose, but it doesn't seem to be any improvement in wave length over the 800

I don't want to sound like I have it all figured out, but from my research it seems the more you can cram into them the better off you'll be. Makes sense to me that comparable boats weigh every bit of 10k with ballasts while the craz is less than 7k... I can surf behind mine just fine, but you have to be super close

I absolutely think you are correct. My boat is every bit of 8700 lbs before you even consider the passengers. There was a time I had full ballast and 12 passengers, I'm convinced that amount of weight negatively impacted the surf wave though.

I agree more is better...to a degree. And I also think the Craz is probably closer to 8k when wet and loaded. Isn't it 4200 dry? Add 3k stock ballast, few hundred pounds of fuel, another few hundred pounds of gear, a finally 500lbs of people weight you're easily pushing if not exceeding 8k before adding anything extra.

I am in the market to upgrade my factory ballast on my Craz. I am curious how this turns out. I was sold on the 1100s until reading this thread.

As long as you have the panel savers installed, will it really matter if they're an inch wider? I have the 1100's, but if I had a do over, I'd go enzo's or custom bags. The 1100's are a huge improvement over the stock 650's, but an extra 300 lbs per side is another huge improvement over the 1100's. Personally I am exploring the best way to add more weight, whether it be steel shot or a piggyback system. I am currently supplementing that with a 600 on the floor when crew size permits. The enzo's are quite a bit more money, but you're not really saving any cash if you end up upgrading again later. That's just my 2 cents, but I'm speaking from 97hrs of primarily surfing in my craz.

[QUOTE=Stimbert;300606]I don't want to sound like I have it all figured out, but from my research it seems the more you can cram into them the better off you'll be. Makes sense to me that comparable boats weigh every bit of 10k with ballasts while the craz is less than 7k... I can surf behind mine just fine, but you have to be super close


had a 2015 mondo with upgraded 2.0 plates. We had 3550 lbs of ballest. Then we would throw in at least 6 people. Craziest wake from a just plus 20ft boat I seen. Are we saying the Craz and Mojo cant take more? The freeboard I think is far above the Mondo. I noticed with my 2.0 tabs compared to the 1.0 tabs I ran 65% on the 2.0 vs 95% on the 1.0 tabs. Huge difference in wake though. the smaller hull of the Mondo creates a faster transition between divergence and convergence creating additional curl. Now if the Craz had that blue whale bow like the Mondo or Mojo it would be a G21 killer. G21 wakesurf is stupid huge

[rdlangston13]

Do the 1100s fill all the way? Do you really gain much more over the 900s?

2016 surf edition moomba- bought it this summer as I assumed the surf issues I was reading about was "rider error"- we had it out each weekend- stock 2500 lbs- spent endless hours trying to dial in, but by end of summer it was the kids/ladies surf boat while the guys used my neighbors wakesetter (also stock). Even with added lead and 1000lb fat sack on the back bench, we called it a 4" wave (need a board 4" longer than we normally ride). My kids are young, my wife thin, so the mojo will work for a few years- but I regret the purchase- I'm 210lbs and am used to a 4'9" board, I need a 5'+ to ride the mojo mid wave! Tricks are out of the question, and endless pumping isn't why I surf!

Not sure which model you're referring to, but I have the 2016 Craz. I had this same problem with mine all last summer and had been consistently playing with this. I'm 250ish and need to have better push than others to do anything with the surf wave. I kept constantly changing variables of weight varying weight in the nose and changing the surf plate. I was weighting the boat evenly in the tail and relying on people in the boat and the surf plate to provide tilt in the boat while under power. But I recently discovered the problem. In order to get the push you need, you have to drastically list the boat to the surf side. Regardless of the people in the boat, the best way to achieve this is to have the non-surf side not completely full. I didn't even have the plate deployed, but the lack of weight on the opposite (starboard) side put enough of that side (port) of the running surface in the water to give me the push I needed. So before you spend any more money with upgrades, attempt full surf side, 50-75% off, plate 60-70% and 2/3-full nose and see how that turns out. I would hate to see you leave behind such a great boat due to you not being able to have some fun too.

[MMPRES]

When I say plate, I mean the surf tab. I have the center plate completely retracted.

[BigOrange]

So forgive my ignorance but when folks state their percentages of tabs -- do they main the side on or opposite of surf side?

[mattsask]

When you select surf port, it deploys the tab on the opposite side of the boat. This allows you to do just as the switch indicates, "surf port".... it should be very obvious. Adjust port settings to surf port.

We have 100 hours primarily surfing on my 2016 CRAZ. I added the wakemakers brand enzo sac to the starboard/goofy side, kept the 1100 in the port and filled everything up. For the first time ever I have a clean wave on the goofy side and I can surf about 20 feet behind the boat compared to the 5 ft I was getting before. I will probably go for the enzo sac on the port side next, it was such an improvement. The port side stays clean evenly weighted for me, but the starboard side needs a few degrees of listing in my opinion. I haven't added any to the bow, but I plan to try a 400lb free sac up there next time we go out.

I agree, it definitely needs a few hundred more pounds on goofy side if you want it to clean up. I just finished installing my wakemakers enzo bags yesterday. Can't wait to get it in the water. I've got to say though, the quality of the wakemakers bags is a bit questionable. I ordered a pair the enzo's and they have completely different port patterns and one bag has 6 ports, while the other only has 4. The seams are nowhere near as neat. I also had to replace my ballast hoses because the ports were in a different location than the fly high 1100's I had previously. That being said, I got a bit of a bargain on them so I'm not complaining.

i run the 1100's rearbags and i guess 650's front, plus the IBS. i fill everything up and place people to list the boat a little. portside wave is great, but starboard is washing out, when not to many people on the boat. no i am thinking to us the stock ballast bags under the seat and fill them with the tsunami pump. i think this is the easiest way to just fill them up when needed. has anyone ever done this? how did this work for you?

[snyderaaron]

I'm thinking about buying lead weight instead. This way I can save my storage underneath my seats

I recently started filling a 650lb bag on the floor with a tsunami pump. I roll the bag to whatever side we are trying to surf on. It has greatly improved my wave. I only use it when we have a small crew size of 4 or less because it is in the way and she hardly gets on plane. I am also running 1100 rears with 400s piggy-backed under the seats, center tank and ibs full. Total weight is 4850 lbs but there is no way the 1100s fll all the way since they don't fit very well. If I had it to do over I would get the 1450lb Enzo sacs. The piggy backed setup is a pain.

I recently discovered that I had my surf tabs deployed too far and it took away from the steepness, push, and wave lip. I was running 70% on the port side but switched to 40-45% depending on crew location.

The extra weight and tab setting changes has allowed me to surf faster. Going faster has made the wave longer and much easier to boost airs above the well defined lip. I was surfing at 10.5 and now surf at 11.3 on the gps. I feel like I finally have the wave I was hoping for.

Update- added the 1100s, and while it made a dramatic difference, I had the dealer on the lake with my wife and me, and it took us over an hour to get a good port wave- only 500 lbs in bodies- we ended up with the following settings: port bag full, starboard 75% and we only fill the center 50% (popping a wheelie!), tabs 65, run plate all the way up at 11 mph. Wave is a bit in and out, but generally surfable.

Sooo... I added a 450 lb sac on the surf side, fill backs full and center 75%, all else the same. Now I have a wave that I can be proud of even with a small crew. Add in some buds and the wave is even better. Sure, manually filling/draining a sac is a pain (often a wet mess), but vs a Wakesetter/Natique it's worth the $30-50k I saved, and spilling a beer on a moomba isn't the end of a future invite. If someone has a good link to DIY plum in extra bag to a moomba, please share!

We still do tend to take out my neighbors wakesetter or nautique for surf sessions as their waves are epic, but for a lot less $ I'm in the game.

All-in-all, I would have paid more up front for the right ballast set up. Seems like Moomba should add weight to the standard boat.

Being new to surfing, I just wish someone would have told me to add 1800 lbs of ballast up front. It would have saved me some frustration initially. Thankfully, this forum gave me all the answers I needed.

Do away with the extra bag and grab some lead. Much easier to deal with and you do not lose any of your storage space. Lots and lots of us running lead or steel shot in our boats on here.

Ill second all of these issues. Upgraded to 1100's for 2017 and going to gps my speedo. 310lbs at 8.7 mph riding my dart 5'6 was all I could get with 750 rears. Wife and kids were fine, slim and trim. We shall see.

What did you do with your old bags? Another $30-$40 in fittings/excess pipe and you can plumb your old bags under the seats into each of the 1100s. You won't be able to fill them 100% as they're too big but it should improve and level your ride. Just make sure the under seat bags are situated correctly when they're empty so you can burp the air the first time you fill them.

[jeamk03]

I run ~1300lbs port, ~800lbs starboard, center and IBS full. Surf @60% (or 80, can't remember for sure). Wakeplate up. 10.3mph. I did GPS check to adjust. Boat had 2mph offset for some reason. Removed it and matched GPS.

I have no prob surfing, even when just my wife and 2 little kiddos. Even better with other adults along.

I first was manually filling the stock bags, but it was a pain draining with my sumo pump- the bag was not full and fittings seemed counter-intuitive. So I bought the 450 sumo bags- a plus is they fit filled under the seats. Easier to fill and empty manually...

What I did was take the vent line from the 1100 and run it to bottom fill on 400 then put a new vent line from top of 400 to check valve then to vent on boat, check valve is to help empty the piggy back set up but even with then we tend to empty while moving with bow high sometimes even while I am surfing it's kind of a game to see how long I can go for.

Grey bag still fills from rear bottom, but the overflow is on the black bag.

https://uploads.tapatalk-cdn.com/20170724/e00ce7e6251618aaff48f2ba00bbb928.jpg

I made a short connector from new fittings from wake makers and some excess vent line already in the boat:

https://uploads.tapatalk-cdn.com/20170724/17d37af4e7bd91ea5d0a5ad4c3792964.jpg

The first time or two filling is a PITA to get the air pockets worked out and the bags laying the way you want but they still empty flat with the check valve installed on the black bag.

Also, on my 2013 mojo there was more than enough vent line to run to the black bags under the seats so I didn't need to purchase any excess lines, just fittings to connect the 2 bags. I'm all or nothin with my ballast so I didn't mess with a shutoff or tee between bags, if you do that you may need to reconsider your venting options.

I had that elaborate setup on my Mojo, but I was using the stock bags and a couple 400s I had laying around. It worked well, but didn't like turning ball valves and having stuff all over the place, so I yanked it all out except for my check valves and installed the 1100s. I kept a 400 and a 155 fat brick on the boat with a pump should I need the extra weight. It really freed up my under seat space.

Marc, try filling your surf side full, off side half or so, full front and run a slight list to the surf side, wake plate all the way up then trim down to clean up the wave, speed between 10-11.2. There is also a "sticky" on here that helps with surf tab %

Sent from my iPhone using Tapatalk

List the boat, add 80 % on the starboard side if youre riding on port side. Only fill the front ballast to 20%, the bow will rise, you'll get tons of push but short wave, then slowly add more water to the front ballast until you get a good wave with good push and adequate length. When you start loosing too much push, cut back on front weight. Set the stbd surf plate to 90% and adjust down from there if needed.
Remember, it'll all change depending on how many passengers you have from day to day, and where they sit. As an example, I was surfing with a great wave, my buddy, who is about 190lbs, shifted seat from surf side to non surf side and it completely washed out my wave. It can be finicky.
I see many state that you must fill all bags all the way and use the surf plates, that has not worked for me.

How long did it take you to do this? I am a complete Newbie, do you think I can do it myself? Is it easy to do? How long does it take to fill all the bags? I have a mondo with 650 bags in rear but I will be surprised if that original 650 lbs bag would fit in the side locker, our side locker on Mondo is like only 22 inch long w battery taking the rest and anchor on the other side. Do you leave it filled for the day? I am thinking with all this weight, probably not a good idea to pick the boat up in the boat lift?
How do you judge how much the bags are full as the sensor on the screen must have been built for the original bags and full on 650 is probably different from full on 1100 plus the side bag if attached.
Also I have heard people saying if you put 1100 bags in the rear you have to re-enforce the middle? Is that necessary and how do you do that?

Yes. Buy a heat gun from Harbour freight <$20. Also, get the wake maker code or call direct and reference this forum. (Probably best to call so you get the correct sized parts). fittings are cheap so I say buy extras so you're prepared for any future mods and not stuck paying shipping again. Probably buy some extra length of pipe too for no more than it costs.

How long does it take to fill all the bags?
~15 minutes

Do you leave it filled for the day?
Nope, just when we are surfing.

I am thinking with all this weight, probably not a good idea to pick the boat up in the boat lift?
Agreed, I wouldn't do that. I don't like pulling into my slip with any level of ballast in the boat.

The %'s on your screen are simply timers and are adjustable. I changed all 3 of my times to the max (I think it was around 22 min) and just turn them off when the front overflow spits and the rear seats start to pop up. You'll start to figure out what %'s your riders like for surf and wake sports and this way you'll rarely need to toggle the fill/empty switches past 100% or 0%.

2018 Update for those taking a look- I added the 1100s in the back lockers, plummed in 450 sumo sacs under the side benches (it took me a couple orders from wakemakers to get the right goodies). Plenty of room under the helm and we wrap jackets around the tower to let them dry anyway (besides, it just looks cool). Now with just my wife and 10 year old I have a great wave. It does take the stock pumps some time to fill/drain (10 minutes or more), but worth it. Total cost was bags/fittings/hoses < $1,000.

Don’t wait- add the weight!

Now I’d like to have Moomba come up with trays for the back lockers!?!?

Has anyone tried modifying the tabs themselves? The amount of sideways push Malibu or nautique seams to be a lot more as the moomba’s tabs don’t really go down into the water that far. Seam to affect roll more than sideways kick.
The tabs have small screwed on runners maybe increasing the size of those? Also here is the tray I made.

Hi. My front ballast on my mojo surf is not filling. I am new to my boat, so I am assuming that this front sack is the only center ballast in the boat. I am trying to figure out why it is not filling even though both rear locker sacks are filling. the switches are lighting up and there is no water leaking into the boat.

Likely an impeller need to be replaced on the pump. Find the pump and pull the cover off.

What sonic said. It’s behind the starboard rear locker carpet panel if I remember correct. If not there then the port side. The front runs longer than rears so it can wear out sooner. Even if the impeller looks good it may not be pumping. Need the Green Jabsco to replace.

Also that front bag under the bow fills up from the overflow of the center tank, so it takes about 6 or so min to fill the center tank under the floor then another 6 min or so to fill the bow bag.
