2012 moomba lsv wakesurf issues

[Danno]

Hi there, I hope someone can help with my issue.

First of all we had a 2007 Moomba lSV, we had a great surf wake and quite a good ski wake as well and all around it was great boat. We had a 1235 acme prop, we used 750 lb fly high sacs in the back corners and with a few people we had a great wave.

ISSUE: we have a new 2012 Moomba lsv and we cannot get a wave or consistency like our 07. We have tried everything the same as the old boat. We are wondering if the hull has changed and therefore it is more difficult to sink the boat (so we need more ballast?) or should we be putting ballast elsewhere in the boat too? We have the 1235 Acme prop on it and have the Digital Cruise Pro.

Any help from someone who really does know the answer that has a similar boat and year would be great and thanks!

I have a 2011 LSV and it's the same Hull. Last year I ran 750 in each rear. Only filled the rear surf side locker full, 370 tube sack under the seats where the cooler was, and 370 in the ski Locker. Had the wake plate 3/4 of the way up and we had a pretty good wave.

This year I'm running a 1100 filled full on surf side, about 40% full opposite side 1100, 370 under seats where cooler was, 370 in the ski locker and 650 IBS wakeplate about halfway up and the wave is huge and long!

To surf the goofy side we just flip the rear lockers and I fill a 370 under the goofy side seats.

Hope this helps

Only real difference is the engine and tower, can't imagine that creating that much difference. Puzzled...

Identical wetted hull surfaces, so my guess would be either your wakeplate is not coming up as far as it should, and/or your speed is not accurate or holding speed. Have you GPS calibrated the speedo yet?

I also think you'd like the 1100s in the rear, but that's a bandaid at this point.

So when you go goofy, do you have the port side 1100 filled? I always thought goofy side didn't want any weight in the other rear bag.

We haven't surfed the goofy side yet so Im not sure just yet. I will see this weekend as this will be the first time my goofy rider will be riding.

Are you sure the bags are getting full? I think a few on here have suffered from their rear ballast bags not filling all the way. Be sure to check that next time out.

^^ Or they fill full but then start leaking off.

The Hulls are the same under the rub Rail so ideally it should run the same wave in both boats.

You didnt mention if your running Regular or Goofy but non the less i think the difference is the Speed control.

So fare in the mojo my biggest complaint surfing is Speed Control Consistency.
I will set it at 10.5 or 10.8 and the boat says its going that speed but in reality its not.
Its always going slower.

Even when i get a good wave, the second and 3rd pulls are not the same wave.

What i have been doing to combat this problem is using the RPMS as my standard. I recently did a calibration on the Speed control yesterday but it was at the end of the day and wasn't able to test out my changes.

With your weighting only difference might be the hard tank, I cant recall if its also 500 in the LSV as it is in the Mojo but honestly this wont matter as much as long as its getting filled all the way.

If possible can you snap a few pictures of the wave with no one in it to see what it looks like. Also note the Speed and what exact weight bags you are using.

This forum can get it figured out for you.

Aren't the 07 and 12 the same boat, 13 was the change that was mojoized.

Zero off keeps the speed control constant. Best option

Ahh yes sir you are correct. Guess i skipped a year LOL.

You mentioned you are running 650 IBS wakeplate? Sorry, what does that mean? Did you change the wakeplate from the original one in your boat? I am stumped by the 650 and if that means pounds or what does that mean?

THanks for your help. I went and got some 1100 pound rear bags and a few side bags (2 x 350's) and 1 x 450 so we'll see what happens. Like other guys have mentioned on this thread it does seem like it is difficult to hold speed consistently. I have digital cruise pro and maybe I should have gotten the Zero OFF GPS?

THanks

I think he was just saying he has a 650lb Integrated Bow Sac (IBS) and that he runs the wakeplate half way down. No changes to the wakeplate.

Ah gotcha, sorry was reading it incorrectly.

GOOD news though! I decided to put in an 1100 lb bag in the rear left (regular foot side) to see if my wave would be better/more consistent etc. As I mentioned when I started this post I had a 750 in there before. So, we filled the 1100 bag to as full as reasonable. We put about 20 % water in a 750 bag on the right rear (so maybe about 75 pounds or so). We had the middle ballast (the ski locker bag) to about 70% and then we had a 200 lb guy and a 130 lb girl sitting on the rear sun deck (regular side obviously) and we had a great wave. We do only have the Digital Pass pro so what we are doing to not get "surging" and inconsistent speed is this: we SET to the ON position and set it for 10. We are actually now wathcing for 2500 or 2600 RPM's on the left dial (so manually because digital pass pro does not have the capability to run solely of RPM so to speak) and when we hit that 2500 0r 2600 we press OFF and then it actually holds that rpm. Now when your rider stops or you are stopping the boat we press it back to ON so that you are ready to be in the ON/cruise position when you pull up your surfer. If you dont do that you will forget and it will be in the OFF position and get too much speed or whatever. This seems like alot of work but just hittin the ON and having it go to 10 and actually stay there DOES NOT WORK with digital pass pro (at least we find that), it fluctuates too much, sometimes anywhere from 9.4 to 10.6 or whatever so it's hard to keep the surfer on the wave. We put a 400 on the rear left seat right next to the tower base and that added even a bit better/cleaner wave. I am sure I can keep adding but at what point is this boat way beyond the weight capacity.

If you have a 1100 in the rear, then you really dont need to add sacs, just the people will be enough. Take that 400 and toss it in the walkway in the BOW you need to fill the 400 bag till its full in the ski locker. The nose weight will make the pocket much longer.

Also with your RPM try setting it to 2800-2900 this will flatten the steep ramp on the wave right behind the boat, it will also cause the Push <power> in the wave to lengthen and make your pocket longer as well.

You can very easily make your wave look like this. This is my 08 but same hull, 1100 surf side, 300 opposite, 400 ski locker and 600 in the nose

Awesome, really appreciate that. I will have to take some pics and post them. Nice to have this forum specific to Moomba to share ideas etc. Thanks again!
