2015 Moomba Mondo Auto Flow Test Drive Dissapointed

[alec]

Hey everyone. So I just demoed a 2015 Moomba Mondo with the Raptor engine. First things first, this 20'6" boat has the room of a 22' boat. It was just three of us in the boat and I never even slightly felt squished in there.

So here is my question. With the auto flow my assumption was fill all the ballast 100% (2,300 lbs total - pretty sure it was 600s in the rear lockers, 500 center, 600 bow) and then pick the side you want to surf and that's it. However when we did this the wave was terrible. It wasn't until we emptied the bow & center to 50% and then port full, star 75% did the wave clean up. Which completely defeats the auto flow in my opinion. We had a pretty big bow rise (ie my 5'2" wife would have to stand to see over the bow) and even with that it didn't clean up all that well.

So a few questions to those with the auto flow system on the Mondo.
1. What set up do you run and do you have video/pitures of what you get from those setups? It seems that this boat should have a better wave that what we saw. We also demoed a Tige RZR with the AVX system and that was one of the cleanest wakes that I have seen.

2. Are there settings within the computer that we should have set differently?

3. How much would a windy day affect the surf wave? I know for boarding that on our lake once we get 15ish mph winds wakeboarding is a nightmare on the knees. But I thought you could surf still even when pretty windy??

4. Am I jumping to conclusions by kind of ruling out the Mondo or was it just that we had a bad trip out and the rep didn't really have the boat dialed in for us?

You can surf with a little bit a chop.

A yes to #4 takes care of the other answers and is likely a good bit of the problem.

I'd give it one more demo before ruling it out. Are the prices comparable between the Mondo and RZR?

[alec]

The prices are within 2G of each other. Mondo - raptor engine, auto flow, the non GPS cruise verison, decent audio. Tige RZR - raptor engine, tige touch, really nice audio, GPS cruise.

I do want to get back on the boat after it is dialed in to get a true test on it. Really think it was forced and the end product suffered.

[wolfeman131]

some guys that have the Mondo are sure to chime in and tell you #4 was probably the issue. What dealer are you working with?

[KG's Supra24]

What's making you give the Mondo a second thought? Looks, interior space, simplicity?

[mattl]

What was your speed?

[alec]

Speed was 11.1 but it seemed slower than that (since its the non GPS version we didn't have time to GPS test it with our phones to adjust that part). I'd say we were more like a 10 mph. The second thought is coming from test drive of the Mondo and Tige RZR back to back. I really think it was a combination of the conditions and the dealer not having the thing dialed in correctly, plus it was a crappy day with wind and rain. I like the looks of the Mondo, interior space was amazing for this size of boat that it is, the second thoughts are coming from the surf wave. Wakeboarding wave took 30 seconds to dial in (that part was easy) had rear tanks half full, bow about 90% and the ramps were clean/crisp and looked really nice. The surf wave was what threw me off. I went into this demo thinking slam all tanks with weight and go. At first we had 2,350 lbs of weight in all the ballast and the wave was worse than my old I/O that we just sold. I pictured the boat in my head as being pretty flat with very little bow rise. However, the only way we go a good surf wave was when the bow was really high out of the water (to the point my wife would litterally have to stand at the helm to see over it if she were driving). So does it need further weight than the factory ballast?

[mattl]

I have a 14 with manual flow and thus far my best speed is 9.5 mph. The faster the worse the wave is imho. Also, I put the wake plate all the way up and run bow and surf side full 85% non surf side. I would say more weight all around with 900 bags in rear and 750 in bow (My order has not been placed yet).

[Jon]

Give the Mondo another shot with better conditions. Make sure the dealer is running the correct Auto Flow settings. 50% on the stbd side plate for port side surfing, 60% when surfing on the other side. If it is a Surf Edition, fill all ballast in the boat 100%. Have an extra person or 2 sit on the surf side. Run the wakeplate at 50% and then fine tune to whether you want a longer or taller wave. Run the speed between 10.2 and 10.5 verified by GPS.

From the video it looks like it was too fast and need a very slight lean towards the surf side with people. Rough water conditions probably didn't help out either.

Be sure to demo just as you would use the boat. If you normally have 6-7 people, make sure you bring that many people or extra weight to simulate it. If you plan on upgrading bags, make sure you demo with upgraded bags. That is with any boat.

I have 900s and 750bow. Wave isn't very long but is massive. Wake plate all the way up and this was 9.8mph very windy though...15-20mph winds http://images.tapatalk-cdn.com/15/05/07/a3433181ba8088f47a99ef100c7de19e.jpg

Surfing is very touchy. Yesterday I surfed my mondo 2014. We used left and bow bag full. Right empty always. , 1 driver and 1 surfer. 8 bags of 80lb concrete left corner seat and left sun area. 9.9 mph. Wake plate right in top position. Excellent.

Really concrete? Get a couple ballast bags concrete won't float much...

Can't speak on the Mondo but I will say this about your other concerns of the wave.

In your video the water is pretty choppy. That chop is washing out the top of your surf wave, Also when you look at your wave the white roster tail is sitting on the top of your wave most of the time. This is a sign your are going to fast. As you speed up more and more the boat wants to plane out and level its self. No matter the weight it will keep trying to do this. This makes the wave wash out as well.

You can surf is less then ideal conditions compared to wake boarding but a rule of thumb is most of the time when winds are over 10mph you can't get a quality surf wave.

The water starts to chop and white cap slightly and this also adds what I call pockets of air in the water flowing under the boat. You can feel this the same as you do wake boarding, wakes the water feel very hard, board wants to bounce more and also at time the water will feel weak and literally swallow the nose of the board and off you go.

You should be able to fill all the Nose wight and surf side 100% and then go 9.5 to 10.5 and adjust the auto flow to clean your wave up, wake plate Up makes wave taller, down makes it shorter.

I don't believe any boat is a set it and forget it, amount of people in the boat, fuel level, weight, water conditions, depth, all play into your wave, the same as it does trying to wake board.

You will have to play with a little and then once you get that awesome setting, you only have to adjust for people most days out.

I have spent countless hours dialing in our Mojo before the flow and after. I have unfortunately not had a chance to spend time in a Mondo to learn there setup yet.

This is a video I made in the Mojo in 13 before the Mondo came out. The Mojo and Mondo have a similar running surface, but this rule applies to almost all waves.

This video shows how the wake plate positions effect the height and length of the wave.

[Horwitz]

Jmvotto, I know the controversy and risks of heavier than water ballast. But, it is cheap, and you can't beat it for ability to fine tune the wake. The majority of the ballast is water.

[sandm]

I envision one of the bags developing a tear and we all know what happens when concrete and water meet.
at the least, buy some lead that's made for the boating environment.

[mark540]

The factory 650's are small in my opinion, i have not surfed my boat yet, as i am still breaking it in, but i did fill bags and such and do a little testing. I am running 1100's in the rear, you cannot do this and get them close to full with the rear panels in place, i have taken mine out and moved my ballast pumps. My friend has an RZR and it is a great surf wave with the AVX, compaired to his, mine is as clean and bigger, so i can only imagine it will surf real well. Wake plate down, surf side almost full, off side half full, bow tank and ibs 100% Auto surf at 100%, I tried the the 50/60 from the factory and it did a little, but not as much as hoped. At 100% you can really feel the boat listing when switching sides. Traditional listing is still necessary, even Malibus and Nautiques do it for the best wave even with the Gates and NSS. My buddy runs 900 on the surf side in his RZR and lists the boat pretty good for that wave.

The RZR is a really nice boat, but is is tiny compared to the Mondo. Tough call.

[Horwitz]

I'm not going to try and defend using cement bags. I know it is on
the fringe. I have them wrapped in several layers of plastic. but I think it's hilarious to suggest that it is better for the boating environment for the environment at all...

[mark540]

Horwitz what bags do you have in addition to the concrete? Do you have the manual flow?

[Horwitz]

Mark I have the stock 2014 bags in back and bow. Again I keep the left rear full and the bow full and right rear empty in addition to some combination of my "C"-bags. Actually the bags are also useful for solemn skiing with only one driver on the boat as they help keep the bow down without using the wake plate to keep the wake flat

[Horwitz]

And yes I have the manual flow system

I think he meant "boating environment" as in a "wet and rugged" environment, nothing to do with "tree-hugging" environmentalist.

[Horwitz]

I know. It's all fun

[Gettin' It]

I've upgraded to 1100s in my mojo and still am not that happy with the surf. My first day to really tune and ride all day was yesterday, problem was 15 mph winds and lots of traffic. Once I found a calm cove I got it to ride best with both sides full, front full, and auto surf at 100%. I also had ten people in the boat, 3 up front and the rest mainly on the surf side. I'm not giving up yet tho, I liked the mojo more than any other boat in its class/price.

[wolfeman131]

I'm not sure how you can dial in a wave w/ 10 people on board.

Dump 10-15% out of the offside, wakeplate 100% up and 10.8-11.1 mph.

Exactly, Yesterday Claudia said the goofy was the very best its every been for the first run of the season, I said because No one is in the boat so its weighted perfectly.

Love all our friends but you have to compensate for their weight as well.

[kaneboats]

Ha ha. My friends have to compensate for me.

[Gettin' It]

I will try that. My 01' Launch I could just attach my surfgate, fill the surf side 750 full and the starboard side half full with zero bow weight. The wave was killer no matter how many people I had in the boat. Learning the new boat.

[BASSINPRO69]

I was ready to pull the trigger on a new mojo but now I'm starting to have second thoughts. I have a 2011 Outback v with 750's in rear locker and 400 in floor. The v surfs ok but was looking for a wave with a lot of push and a bigger boat. So are you saying you should have gotten a different boat.

For the price and size you can't meat a Mojo unless you buy used.

People just have to understand NO boat is set it and forget it.

Every boat I have ever been on takes dialing in, I see boats all the time at the lake that have crappy waves but I know that boat can do better.
For example, Centurion Saturday, surf wave was so bad even Claudia wanted to help them make it better.

There is always factors in making a surf wave, wake board wave and to let a couple people tell you the wave sucks, vs all the ones who have the boat who says the wave is awesome is not a justification to not buy something.

As always you should read up on this forum about the Mojo, how to set it up, listen to those who have spent the time to figure it out.

Lastly water test the boat. After you have some knowledge on how to dial it in, in most cases you will be telling the dealer what to do.

I talk to AWS all the time on how mine is set up, this way they can replay to the new customers how to do it.

Granted we are talking about a 15 Mojo and its a 23ft but in the end to get a decent wave shouldn't be real hard on any boat in the SC line up.

I can guarantee you the Mojo will throw a bigger wave with more push then your OBV just due to sheer weight capacity. But when you add more weight you have to do it properly. Just like loading a truck, you can't put all the weight on one side and expect it to just work. it has to be loaded correctly.

[BASSINPRO69]

I was also looking at the new Axis T22 with the surf gate. Iyo do you think the auto flow is the better choice? 65+ is a lot to be spending when you aren't sure and second guessing yourself. Think I should just wait till I get some more opinions.

[KG's Supra24]

You should personally drive both.

They are different boats; each having pros and cons.

Agreed 100%., after riding 10 different surf boats at SSF , it's amazing how different they can be and how they should be dialed in to " surf the perfect wave" it takes some tweaking and your preferences dictate the wave you like.

[KG's Supra24]

And you gotta know if you can deal with that axis interior ;). Although I think the T series is better than the A?
