Mojo Surf Ballast Setup

Hi, just installed the new ballast today. For the 1" TH I have to enlarge the stock holes (didn't take tool to do it). We tested (only 1 driving and 1 surfing). Speed was 15km/h (9.4 mph) max otherwise the wave become dirty. Wakeplate 3/4 up. Starboard ballast 20%. How much did you put in your starboard ballast when wakesurfing ? Did you fill 100% the IBS ? The lake today was not flat at all so maybe it's not the best to test. We will test again tomorrow with more people onboard. About the propeller, did you change it?, it seems the boat as much more difficulties to move all that weight compare to stock ballast !
Timer setting (aprox) Left 13min (1100+370), Center 11 min (stock + IBS) & Right 11min (1100)
Thanks for feedbacks
p.s : my hands are ruined with these damned hose !! even with heatgun !! Especially the "Y" connection !

gurt, I surf with port locker 1,100 full, 370 port full, center full, IBS full and starboard locker 1,100 about 25-50% and @ 11.1 mph with the wakeplate anywhere from 1/4 to full up. The wind and water conditions can impact the wave, but I'm normally able to clean it up pretty easy. I upgraded the prop from the factory and have the 345 hp motor & have no issues at all getting moving.

Thanks

That's what I run in mine with the addition of a 400 under the side seats. I do not fill the opposite side at all. I've found that does NOTHING to help IMO.

for the LSV, I tend to agree. for the Mojo, it needs the off side weight.

I used the upgraded clear tubing with the black plastic embedded. I place the end of the tubing in boiling water for 30-45 secs and it becomes very flexible and slides over connections with minimal difficultly.

Hello Wolfman, thks for infos. So your prop comes from moomba? I saw some prop from wakeprop.com
Did you remember the model that you have? thx
I don't have issue but it looks that an other prop would be better..

after replacing the prop, did you have to calibrate something because speed at same rpm change or is there a sensor that doesn't depend from prop?

Drew has the Acme 1235prop, I do too. nothing to recalibrate, bolt it on and go.

I think most everyone on here with a Mojo has the 1235 and it does the job without complaint!

That is correct. 1235 has no problem even at 5K of ballast.

Got my LSV setup today. Took around 4 hours in 100 degree heat. Props to Salyers for the boiling water trick. I put the connectors in the freezer while the water came to a boil. I would then put the end of the line in the water for about 10 seconds, and then the cold connectors would slip right in.

I'll be on the lake first thing in the morning to try it out. Thanks for the great thread.

LOL. I was taking down my "solar" pool heater yesterday. Couldn't get the hose to the heater to slide on the return after I cut the heater out. Nuked a cup of water and soaked it in there for a minute. Slid right home, clamped her down. Great technique.

Thanks guys, I'd love to take the credit but I learned that trick from my Dad when he installed most of the plumbing in his new house. Saved me lots of sweat and four letter words over the past year.

Shoot, I hope Dad doesn't have ballast hose for plumbing all over the house. Then again, bet that house throws a mean surf wave if you can get it moving to 10 mph.

The ACME 1235 is the prop I'm looking for. The guy from wakeprop suggest me the ACME 2079 for my mojo with that ballast config.
I'm afraid about top speed with that 14.5" x 12" prop
As somebody this prop (seems to be a new one) what do you think guys?
The boat is not well with the stock prop to push that weight! And fuel is burning so fast!
I will order the prop next week. As somebody already changed the prop with the boar in the water or is it a bad idea?
Thanks and enjoy w-e

I'm not positive but that 2079 might be the new prop for the Mojo, I know when i talked to Wake Props they mentioned a bigger prop for the Mojo due to clearance. I would just stick with the 1235 as its a good solid proven prop, plus if for some reason you ever want to sell it, it fits a lot of boats.

As for changing the prop in the water, prolly wont work to well.

When i took my prop off, the drive shaft spins very easily. Plus on the Mojo the Prop is centered with the Ruder to allow the boat to track in a straight line easier. Very hard to get much more then a wrench on the nut. I had to place a block of wood under the prop for it to dig into to stop the shaft from rotating and break loose the nut. Don't remove the nut all the way, leave it on a few threads. When you use the prop puller and the prop breaks loose it till catch on the nut instead of dropping off the shaft.

Changing underwater is "in case of emergency only" if you ask me. It's very easy to do on a trailer. Harder to do on a lift and very difficult to do underwater. Now, if you have diving gear and want to play around maybe it would be fun.

Went out this morning. The wave was great... The wife was less than thrilled. She'll get used to driving with all that extra weight & list with more time. She was full of great things to say after she turned too quick and took a big splash over the bow.

On my second time up, I was able to ditch the rope. Something I could have never done with the stock ballast.

Next I might need to investigate a new prop. Looking at wakemakers, they don't show the 1235 for the LSV, but rather the 1433. Any thoughts on this one ?

Honestly if your going to buy anew prop for the LSV get the 1617. I ran that on my LSV when the Wake Board prop wouldnt do it anymore. I got better fuel usage as well and the top speed didnt change from the wake board prop.

1617 is a beast of a prop, and its super quite.

what is a hippity hop ball?

Nevermind, figured it out and found them. Does anyone have a discount code for Exile?

Raining here today, looks like it may be an expensive day for me with online shopping.

Yep, I was looking forward to getting out again today with the new setup, but woke up before 6 and saw rain was already in Ft Worth, and was about to get us. I drug myself out of bed, and the boat back to storage. Was back in bed by 6:15. Who would have thought it would rain here in July. Oh well, the lakes need it.

I'm running exact same set up as drew and this past weekend we tied the boat at dock ballast fully loaded when we got back on boat 1.5 hours later the now sack was empty. So I flipped switch ran down to empty and refilled. Now the now sack seems to drain to about 1/2 while surfing. Any thoughts?

I checked all of the fittings on bow sack and hard tank (the 2 you can see if you remove the circular cover in floor). No leak. I also filled the bow sack in the boat on trailer and out of the boat in yard no leaks.

Did you check your impellars? I assume the water insnt draining into your hull?

LSV your inbox is full

Wolfeman, why did you install check valves on the vent lines?

The check valves prevent air from being sucked in through your THs, and make your bags drain flat & look like a raisin.

I am having trouble finding someone who stocks those 3/4" check valves here in Canada.
Also, (stupid me)... When i picked up my 1100's, i considered getting the thread in couplings but thought, "no, I'll re use the ones that came with the bags"..... Since then i have learned about the glue, the hair dryer and how to pop them out... Trying one more location to get them couriered to me before i try to pop them...
While in the process of trying to source the thread in coupler, i made sure to check the sizes and determined the OD of the coupler is 3/4 for the vent and 1 1/8 for the fill ( i kept referring to them as 1")

I did the hair dryer for about 10-12 minutes on mine, and it unscrewed pretty easy with channel locks. Wear gloves. I had to do that to remove the 3/4" vent from my center bag so I could change it out to the 1" to fill the IBS. I then re-used that fitting for the vent line on the IBS.

Guess you don't want to pay the taxes and shipping rates from wakemakers.

Shipping, taxes and duty and TIME. If i had more time i would use wakemakers and use USPS, and eliminate duty charges. Main concern though is time... If they come from canada, i can get them in a day or two.

I will try your method but i want to get the fittings in first cause if i wreck it, i wont have any bag to fill. Once the 1100's are in, i will cap the 400's for bow ballast using tsunami pump.

Not sure where in Can you are but flowrite is in michigan. You can order direct from them and the fittings are 50% cheaper than wakemakers

New 1100's and bow sack shipped today! Whoop!

Hy, I have some pictures of my ballast installation (same setup as wolfeman)

Here is a maybe better picture of the Boshworth valve :

http://img.imagesia.com/fichiers/a4/...a4bn_small.jpg

And I add this valve inline with the fill of the 370lbs under the seat so I don't have to disconnect any thing :

http://img.imagesia.com/fichiers/a4/...a4br_small.jpg

And here are some pictures of my ACME 1235 installation (I was today) and I will test it tomorrow !
I hope it is better than stock because the size and pitch are almost the same (14.5 vs 14.25) :

Drifter, they should be here Tuesday.

trmaggie98, I'm sure you will enjoy with these ballast !! But You will probably change the prop due to extra weight...
For my 2012 mojo the stock prop was 14.25" x 14.5" and the ACME 1235 is a 14.5" x 14.25" so quite the same. I would choose the ACME 2079 with 12" of pitch ! I will try my prop today, hope it's better otherwise I will go for the 2079 and sell my 1235. Give you feedback tomorrow.
One more thing, I was always wakesurfing with a lower speed than everybody (same boat, same ballast...) so I checked the speed with a GPS and it was wrong. The display was about 2mph lower than real speed! So I was at a correct speed when wakesurfing (about 10-11 mph) so I adjust the displayed speed with the menu -> adjust paddlewheel or something like that and now it's fine

Gurt, did you glue the fittings into your fat sacs? Mine spin and spin and don't seem to tighten. Did you use pliers or just tighten by hand?

Thanks,

What engine do you have?

I have the 350 surf engine, run 3K of ballast and 10 people with no issues wake surfing. No cavitation or anything.
I have no issues pulling people up.
I am also still only using 3.5-4 gallons an hour.

Hy, no I didn't glue the fittings. I just tighten by hand but it spin also. The fittings on the stock ballast were glued by the ex-owner. I will glue them I think because water flows by the vent when full.
About the prop, the result is good now with the ACME 1235 ! with the stock prop, I could wakesurf without problem with the ballast full (~3k) but I had some vibrations and the boat was not really able to go faster than wakesurf speed. The wave look better with the ACME prop (or it is psychologic...)
