New Moomba owner, intro & build/fix thread

[shaneo24]

Hi Y'all!

I live in Austin TX, moved here 2 years ago and was immediately bitten by the wakesurf bug by spending our first summer out on Lake Austin & Travis with friends with boats.

Since last summer, I've been passively looking for a good deal on the right boat and... I just purchased my first "starter" boat.
2004 Mobius LSV, 432 hrs. New vinyl, new $3k stereo (previous owner owns a custom audio shop), a crappy wrap that I'm sure is hiding some gelcoat weathering, but the hull is in great shape and seems like a solid boat. I think I'll keep the wrap for the season while I get used to driving the boat, and pull it off next Spring & see what kind of condition the gelcoat is in, and attend to that as needed.

It came with some smaller rear fatsacs, and a really large fatsac in the ski locker that I have yet to use (no idea weight of them yet). I have no idea if the ballast pumps work or not, as the seller didn't use them and had the bags in storage when I test drove it. That makes me think the pumps don't work, so that'll be a bridge to cross very soon.

Parts already bought, after my first weekend of ownership - new drive belt, new tracking fin, temp gauge and sending unit, more jackets, wakesurf rope, starter wakesurfer for my fiance, fenders, tie down ropes, anchor, and other small stuff. I'm a big DIY'er so I plan on tackling all of this myself.

First, I promise I have searched the forum for these answers before asking!

I do have a couple of things that need attention, and hopefully y'all can help;
1. These wires (pictured)... does anyone know what they are for/where they go? One is a positive & ground combo, the other wire clips into something?
The wires were hanging loose when I was inspecting the engine bay & absolutely no idea what they are meant for. Blue circle is where the wires are coming from, red arrows are the wires.
2. Best places to find OEM replacement parts? I've found Bakes, Overtons, Wakemakers, but not many places to find ALL OEM parts if I ever need them.
3. Best rear bag weights for wakesurfing?
4. Best wakesurfer for me? I'm 6 ft 185 lbs, athletic. Last summer was my first time wakesurfing, I have gotten up every single time and by the 4th time out I could ride without rope. So, I think I'm looking for an intermediate/advanced board, that will allow me to gain more skill without having to upgrade over & over - but too new to understand what I need to get!


Anywho, thanks all! I look forward to learning and contributing as much as possible through my Moomba ownership!

Cheers,
Shane

Well, I keep trying to add photos but the forum comes up blank after every upload. If anyone could PM me and help out there, that would be great! Thanks again.

If you are a brand new member your pictures might have to be cleared by a moderator before they post. I think it used to be that way, not sure if it still is. Might explain why they aren’t showing. Welcome to the moomba forums

[rdlangston13]

Chaos make some good board and as a bonus they are located right there in Austin. I would check them out for sure.

For OEM parts looking into skidim.com they have a huge selection of OEM tow boat parts.

For a 2004 Mobius LSV you may want to consult with bergemeister or how every you spell it. I think his LSV is about the same year model. I had a 2008 but it is a different hull than the 2004.

Welcome to TX and be sure to check out the Moomba/Supra TX Jam we host every year on the Trinity River just outside Huntsville, TX. https://www.facebook.com/groups/1953830211561796/

This years event is the last weekend in July.

berg's boat from the pics I have seen is immaculate and would use him as the catalyst to what you should aspire to :)

that being said when it comes to the ballast first order is to hook up with MLA on here and ditch the sprinkler valve/single scupper setup to a 3 thru-hull setup. faster fill times and eliminating the flow robbing sprinkler valves is a must.

good luck and as they say, pics or you didn't buy it :)

Nah there’s been an issue uploading pics for a while now. I wished they would fix it so I don’t have to dump stuff on imgur just to post a pic here. Also wished they would lift the 4 pics per post limit but I’m ranting lol

Welcome to the forum shaneo24!

[shaneo24]

Hey Everyone,

Thanks for the insight! As for pictures this is the best I can do for now.

David, I joined that facebook group, thanks!
Sandm, are you talking about a factory ballast upgrade like what Wakemakers offers?

[shaneo24]

Ugh, so sorry y'all...

Sandm, are you talking about a factory ballast upgrade like what Wakemakers offers?

not sure on wakemakers stuff. pm MLA on here. mikes liquid audio. he has taken care of me on my last 2 boats and knows what to ship ya and walk you through the wiring and anything else you need. customer service after the sale is first rate.

and he'll walk you through losing all the old sprinkler valve parts. slow ballast fill times and prone to issues.

[sandm]

here ya go. nice ride

Hi All,

Tonight I got back in there, found the positive+ground wire was for what I think is my right side ballast pump. Tomorrow I'll be reconnecting and hiding the wire up away from the manifolds, which I think may have caused the wire separation in the first place.

Still nothing on the snap-in wire. It is black & yellow, my first thought was to get underneath the dash but there's multiple yellow wires underneath there, so I will try to trace it back to a switch - somewhere...

---- Where should my blower motor be located? I did as much research as I could, and think it should be on the starboard side under the mufflers, but I couldn't see anything back there - and I hear nothing when I hit my blower motor switch. ----

To be continued!



(Apologies for posting links as opposed to actual pictures, I think I may not have enough posts to add pictures yet)

Blower in my '05 is located on the port side. Remove the divider panels to get access. Invest in a wave shaper or build your own "suck gate". You can find plenty of specs on line. Easy DIY project and will make a huge difference in the surf wave. We all surf regular so we have a 750 in the port locker, 400 in the starboard locker, 400 in the floor locker and 300 fixed weight in the front and we have a great wave with our '05 LSV which is the same hull as your '04. We have a separate 400 sack we fill with a tsunami pump and set on the seat but most of the time we don't need it.

[shaneo24]

Thanks VA LSV, that info is awesome for helping me figure out what kind of weight setup I should run!

- So I had my first official launch today, a couple of things;
- Belt needs replaced, was so tight a couple of times the engine wouldn't turn over when we went to restart to surf other spots. I already bought the new belt, just need to install it tomorrow.
- I did find the blower motor, but it didn't work. Blade was gummy and seized up. Ordered another and will replace asap.
- Quickly found out how overly complicated the ballast system is. Only a couple of the pumps worked, and since each has a one-way pump, there's 6 I guess? - so that should be fun. I'm looking at this Wakemakers (https://www.wakemakers.com/supra-moomba-ballast-system-upgrade.html?gclid=EAIaIQobChMI85fRh7KQ4wIVz7bACh0 bXQrpEAQYASABEgJO0_D_BwE) system upgrade, seems like an all-in-one package to fix the issue and upgrade the pumps to the brass reversible pumps (like sandm eluded to earlier this week!).
- Carb needs tuned - hate carbs. (insert EFI conversion wishes & eye roll here).
- Had a bit higher idle than I'd like, v-drive light was on as a result. Might be the TPS, could just be an adjustment, oil is new so I rechecked level and that's fine, pressure seemed fine according to the gauge (right in the middle all day at 40 I believe). Could also just be another effect of needing a carb tuning. Will check v-drive oil tomorrow as well, didn't want to check while we were out on the water and forgot to check when we got off the water as I know you should check it while the engine's warm.

Any advice and help to work through these troubleshooting & fixes would be greatly appreciated!

It turned out that 5 out of my 6 ballast pumps were bad, so i couldn’t even pump out the water that went into the one bag that was filling. I went ahead and bought a full kit that comes with 3 reversible 780gph pumps, all new harnesses, new thru hull fittings, etc. Wakemakers builds this kit to order and apparently doesn’t stock enough of them in peak season - plus they had to get them shipped from Mars so I have been waiting on them for quite some time and getting really anxious to start this project.

Onto my ballast Question:
So, my LSV came with the Gravity Games ballast setup, which is only 1200lbs total ballast - 400lbs in each locker.
Ideally I’d like to put some 50x24x24 1100lb bags in the rear locker, as much as I can fit in the center locker, and 300+ lbs of lead in the bow.
I took the center bag out and measured the inside, which comes to 70”x20”x10”. If I bought that size bag, it would give me 570lbs + the 300ish lbs of lead in the bow - would come to around 900lbs total up front.

Would I still be able to run the 1100lb bags in the rear with less than 1k in the front? Or should I shoot for 750-900lb rear bags?
Apologies if I am regurgitating something that should be obvious, this is my first boat and trying to see what the max ballast I can/should run in this boat. I am not the type to do things as I go, nor do i do them half heartedly. If I’m upgrading the ballast pump, plumbing, and wiring system I want to go ahead & get the max size bags I can use so that I’m not constantly upgrading bag sizes.

Thanks in advance!

My previous boat was a 2008 Outback V (purchased new in 2008 and sold in 2018) which is the same hull as your LSV I believe. I don’t think you are going to be able to fit anything larger than 750’s in the rear lockers.

The stock 400 in the ski locker plus 300lbs of lead in the bow should be plenty up front. Then with 750’s in each locker and a wake shaper you should have a legit wave with a few people in the boat sitting on the surf side to give a little bit of weight bias. On light crew days take one of the 400’s you removed from the rear lockers and put on the surf side seat in the back.

I upgraded my boat with the wakemakers kit plus I added timers for ease of operation which I recommend. I believe I posted a thread on here when I did it, let me look for it and I’ll post it up.

[z28ke]

Congrats on the new boat btw! She looks great!

I guess I never started a specific build thread but here is my “for sale” which lists some of the things I did to it.

When I get a chance I’ll see if I can find some pictures on my phone from when I did the reversible pump upgrade to help with ideas on where to mount them.

[z28ke]

Found some pics:

I mounted the ski locker pump to the back of the rear bench seat, no pics of that.

I made brackets to mount the 2 rear pumps on each side of the engine:

https://uploads.tapatalk-cdn.com/20190719/94f803b781386530bf6e7304db90d44f.jpg

And mounted the timers to the aluminum crossbar at the top of the engine compartment:

There are many ways to accomplish this upgrade but this is how I went about it. Hopefully this helps

[shaneo24]

Z28 you are correct, I went back and re-measured the locker and it’s 50x24x20 so the 1100 lb bags are 4” too tall. But at those measurements I’ve seen 1000lb bags, is it ok to max out the usable space back there?
I haven’t researched much on the timers, do you have to manually set every time you fill?

Yea I’d say go ahead and fill it up! The timers cut the pumps off automatically at the number of minutes runtime you set. It takes a few times to get the set time adjusted properly but once you do, you can flip the switches on and it’ll stop filling once full, and the opposite when emptying. The added benefit is when draining you can’t forgot to turn the pumps off and burn up a impeller.

The timers essentially make the ballast system more modern so you aren’t having to monitor the bags when filling/draining. Without them the filling part is easy because it’ll start peeing out of the vent when full, but draining you need to keep an eye (or ear) out to prevent possible impeller damage.

Myself and the crew being able to chill and relax was worth the added cost to me.

Welp, I got the Wakemakers kit in after waiting a month, and they didn’t send the hole saw to drill into the hull (they don’t sell 1 1/16” at HD), so I’ll be waiting for Amazon to get that to me ASAP!
Anybody do this upgrade & have any tips for me? I already know how & where to drill my holes, wiring needs to go up through the starboard gunnel, but anything other than that I’d love to know.

My local mom & pop tire shop gave me 300 lbs of wheel weights for $40, wonder if I should melt it down into ignots or just buy some empty Mission Atlas bags and throw the weights in those. Has anybody ever gone this route for lead ballast?

As y’all know, the old LSV’s are lacking in the storage space category (especially loaded with ballast). I yanked out my 12” sub and will be buying a much smaller setup (10” kicker tube combo to be exact) to give me some space under the helm.

Anybody in Austin want to buy this one for cheap?! Rockford Fosgate T1 sub with waterproof ported box built to spec, 800w rms/1600w peak. It’ll shake your boat and your soul!

I did this, it sucks. I had a full bucket, got 70 lbs of actual lead out of it. Not a lot of tire weights are actually lead anymore.

If you want to use it as it sits, make sure you wash it all, and clean all the trash out of the weights, because the tire guys throw all kinds of crap in there, ash in it, and throw their cigarette butts in with them. Pretty gross. https://uploads.tapatalk-cdn.com/20190802/b3a8b59c6e46e666bf6f9e1f724eb9ae.jpghttps://uploads.tapatalk-cdn.com/20190802/a35456f43f7de9694dd4de3bbfe5c5e9.jpghttps://uploads.tapatalk-cdn.com/20190802/00bf7649197d37cc8d4caa07a5bdcb09.jpg

I would put wheel weights in a Home Depot tool bag and call it a day. I also would minimize handling lead.

It’s an upgraded intake with a larger 84mm throttle body. From the factory it was part of a $20k power kit. She has about 620hp/650tq as it sits now, this won’t add much power but will smooth out the hp/tq curve.

Nothing stays stock in my house!
