Can you guys help me get a better wave? 2005 Mobius LSV

[Speed Freak]

Hey Guys,
New to the forum. New to wake/surf boats. So can you guys dumb it down for me. LOL. I posted a WTB in the classifieds for some ballast bags. But I need to know if I'm heading in the right direction.

I have a 2005 LSV with the Gravity 3 system. Budget 6-7 hundred bucks. I have a DIY gate. Primary surfer is my 13 year old. Wake makers has a 2x1000 lbs bag system for around 450.00 so I was thinking that but I just want to be sure its the right way to go. Any information is appreciated. I am hands on and can do most any type of DIY stuff. I don't mind piecing a kit together if it saves me money.
Thank you,
Guy

Get a bow sac to go with the 1000lb rear sacs. You need the weight up front to keep the bow down and make a nice wave. I ran mine once without the bow sac and it wasn't even surfable. I put a 750lb ibs in it and now it throws an awesome surf wave. You'll want to upgrade the pumps eventually too it will take forever to fill all that ballast with the stock pump setup

Agreed with above. Installing an IBS will give you a longer wake , so youre not surfing right on the platform. Pair that with a couple 1000s in the rear and youre set. No surf side boas required as you already have a shaper.

Different boat.

The 05 lsv and 07 obv were the SAme of hulls. 750 in thevrears 1100 too big

650 inthe bow and 400 in locker plus ghetto or suck gate

What IBS are you guys using? Can I get one that goes under the seat area?

I also have a 2005 Mobius LSV w/gravity 3 ballast. We took the 2x 300lbs rear bags that were stock and moved them under the front bow seats. (You will need a piece of wood or something to brace the passenger side bow bag from sliding into the battery). Bought 2x 750lbs fat sacks for the rear, with the stock 400lbs in the ski locker and a suction gate you will be set.

That hull maxes out with about the 750's so don't pay more and you can find them used from guys with LSV's, etc. that can go larger. Get a pair and then some weight up front, add a sukg8 and you will be good to go.

I used the ibs 650 and got it 85% full, it will pop the seats though.

These are what I went with in my 2007 lsv. You could go a little bigger in the front but not much. The 910's fill the rear lockers.
Use the wakemakers code to save some $!

When I had an 02 outback lsv i had 750's in the rears 375 in the locker, and the sumo 550 ibs, with a suck gate the wave was very clean and big. Hope this helps

How did you plumb them in under the front seats?
Off the center bag, separate pumps just for them, or filling manually?

[Hayden]

We just use a tsunami over the side and keep them filled permanently. We do surfing and pulling kids on tubes, so maybe if you're doing skiing or wakeboarding you'd want to be able to drain them often? Regardless, we leave them filled and drain everything else at the end of the day.

You could also run a line from your center bag to fill them. By the time your 750's in the rear fill they will be mostly full. You'll have to add a drain pump for each bag though.
