convex vx issues

[barry1me]

I have read where some people are having issues with there convex VX attachment on where it comes off the hull or by the angle of what it comes off the boat. Can anyone confirm if they have had issues and what to look for? Im picking up a Z1 with convex VX and want to make sure it has the correct convex VX attachment.

When I picked up my Z3 from dealer he said that the bracket angles are wrong and new ones are on the way and it was better with out it on till the new brackets came in. He also said it was only on the Z3 so you should be good.

I have been receiving a few emails and PMs re: this issue.

There is an issue on the production VX that Tige is addressing and information should be received this week. I will let Tige release their info first, but basically the production VX will not produce the same results as the one you are seeing on our Wake9 Z3. This issue is being resolved ASAP and we have requested a new production VX with the issue resolved on our own boat, so that we are riding the same thing that everyone is buying.

I can tell you this, the Z3/Z1 is definitely better with the VX when it is installed properly, or we wouldn't have it on our boat.

Does that mean that the current VX is the correct one, or is the wake 9 version the correct one?

Please elaborate,

Should we all be asking for a new Convex VX once this issue us solved?
Is the issue across all boats?

[Travism]

I have been going through this as well.

What a headache. I was told I needed more ballast so spent around 2000 upgrading from the surf setup to the pro bow setup and custom rear sacks.

Now the brackets are wrong ....

I need a Tylenol

[ragboy]

I am sorry man, if I was in your shoes, I would be frustrated as well. The ballast works great with the VX, and the VX surf wave is better than without the VX. That is not just our own opinion but we got the same feedback from riders that rode our boat before, and after with the VX dialed in. Its smoother, cleaner, better transition, better shape, and the lip is better. The curl from the Z3 wake is also almost gone with the VX, but there is an issue with the ones coming out in production. It effects the Z3 much more than the Z1, but its a problem on both.

Tige just released an email to all dealers informing of the issue. I only have a screen shot of that email but it basically says if you have an issue, you need to see your dealer. I am going to show you how to measure to know if you have an issue. My guess is that most or all of Z3/Z1s with VXs have this problem, and I am not sure about the other boats.

How to Measure
First, let me show you how to measure, with pictures. You need a long straight edge and a tape measure. You will place the straight edge along the running surface of the hull along the edge of the trailer bunk so that it is flat against the hull at the back of the boat. Here is a picture to see what I mean.



Then with the straight edge extending out to the end of the VX, you measure the distance from the end of the VX to the straight edge. Here is a picture.



As you see in the picture, you should have a measurement of 4 inches, or at least between 3.75 inches and 4.25 inches. Anything outside of that should be checked.

The Problem
Many production VXs were installed on Tiges with the measurement at around 2-2.5 inches which sets the VX too low and it acts like a big taps plate down all the way. So you lose adjustability and can't get the wave any steeper or generate the kind of push the boat is capable of.

The Resolution
We noticed an issue when we tested the Z1 but thought it was due to shallow water. It wasn't until we received a new Z3 with production VX at the West Coast Open that we knew there was an issue. We modified the VX ourselves and sent immediate feedback, video and pictures to Tige. Since then they have been working to resolve the issue. First making sure that the measurements we gave them were optimal with a lot of lake testing and then making new brackets and then working out a plan to fix and get to dealers.

We are headed to Texas and will be spending a few days testing all boats and video taping to confirm. We have also arranged so that the wake9 Z3 will not have a prototype VX but a production VX with this issue fixed so that we will be riding the same thing that everyone is buying. And then we will continue to work on even better, cooler, funner stuff. ;-)

Finally
For the record, the moment we realized this to be the issue we jumped on getting the info to Tige immediately. Since Tige received this info during the WCO they have been working to resolve and are committed to fixing the VXs out there that need to be fixed at no cost to the owner.

I am confident that when you get the VX on correctly, you will love the wake and be able to see the same results we have.

[ragboy]

I will post this again here, all of this surfing, with various people is with that VX installed properly. We are just using those custom sacs, 1235 prop and that is it.

Also, RJ and I are very excited to try the Z1 again with everything correct, and we will have our custom sacs in it. We both think its going to be amazing and can't wait.

convex vx issues

What's interesting is that Post #27 is this thread: http://www.tigeowners.com/forum/show...013-RZR-Stoked!!! shows a VX that has a different shape on the sides of the VX. Granted, it's on an RZR, but mine looks the same as this. What I mean by different shape, is...compare the sides of the VX in Ragboy's picture above and in the thread referenced here. Look how much taller the sides are on Ragboy's prototype. The trailing edge of the production VX's look to taper down more than the prototype. I would think this (in the prototype) essentially creates a "surfgate-ish" piece that is taller extending further back, thus diverting more water under the surf wave creating more push. In contrast, the production VX side tapers off, allowing that water to flow to the centerline of the wave sooner. Thoughts?

Here's mine.

[WakerideN]

I dont own one of these contraptions... but as I sit back and watch.. I am confused how you go from prototype to production.. and have this many issues? I am confused why or how this has gotten all screwed up?

[ragboy]

We have had the VX from our boat, and a production VX from the WCO regular Z3. Everything that touches water is the same. As I understand, the VX on our boat was used to make the molds for the others, at least for the Z3/Z1. Once we adjusted the production VX to match our measurement, it worked the same, beautifully.

exactly my point... how is it that the FACTORY is screwing it up... and your not.... this is insane to me?

[ragboy]

I agree this is not optimal. ;-) But I can't speak for the factory. I know they are spending a lot of money to test, and get it right. They also didn't hesitate to approve and reimburse any of our expenses related to resolving this for the events, etc. Then paying for our travel out to test for up to 3 days if needed, there is a high level of commitment there.

I spoke to my dealer about this issue with regards to the Z1 with VX that we took delivery on 2 weeks ago. They mentioned they had just recieved the update from Tige that ragboy mentioned. I asked the dealer if I needed to verify anything to assure that our boat had the issue since it was recently built (arrived at the dealer about 4 weeks ago), they stated that it appears to have been an issue on all of the "Z" series boats. Tige will be sending new mounts, the dealer states it is an easy change. No ETA at this time on the parts.

Ragboy. Would this adjustment be part of the reason that everyone is stating they need so much additional weight to get a good wave? With the angle being down more, I am guessing more weight would be needed vs. if it was at a higher angle. Is this a safe assumption?

[ragboy]

@dandy, yes, with the wrong angle, you would need a ton of weight to counteract all of that lift. We needed only about 300 lbs more on surf side with the VX.
