Problems with Goofy Side Wake on RZ2 with Convex VX

[Coop]

I have a 2011 RZ2 and got the Convex VX over the winter. I have the factory surf ballast with the exception of 600# plug-n-play sacs in the rear lockers to replace the factory 350# sacs. So, with the 250# hard tanks, that's 850 lbs on each rear side, and a 400 lb u-shaped sac in the bow. I have run it anywhere from 10.8 mph to 12.0 mph, but usually around 11.6. I've always thought the wave was big enough, but it was a little short and steep, and that problem is worse on the goofy (starboard) side. I was hoping the VX would lengthen the wave and mellow the transition a bit.

That seems to have worked some on the regular side, but not so much on the goofy side. For goofy surfing, I run the starboard side rear sac and hard tank full, and the bow sac full. I've tried putting more weight in the starboard side front (both sacs and people), but it doesn't seem to help much. I've also tried filling the opposite side rear sac/tank some (anywhere between 10-50%), but that just seems to create more prop wash on the wake.

I also tried to lower the TAPS, and here's my biggest problem with the VX. If I take the TAPS any lower than 4, I get significant prop wash on the goofy wave. That did not happen before I installed the VX, and it does not happen on the regular side with the VX.

Any thoughts on the above are welcome, but I'm most frustrated by the TAPS/prop wash issue because (1) this seems to be VX-related, and (2) I was hoping to use the TAPS to lengthen the wave some. Anyone else experience this problem?

I just realized as I got to the end of this post that I can't find any good recent pictures of the wave. I'll try to do that and post them soon. Thanks for any advice you have.

Have you tried more weight? Mine is washy with 850 but clean with more then say 1100.

I did borrow a friend's Enzo sac, and it didn't seem to help much with the TAPS/wash issue. Of course, on the starboard side, that sac is limited by the built-in cooler. I also tried putting some fairly heavy people and/or an extra sac along the seats up the starboard side. Same problem.

I've thought about taking the cooler out, but since things didn't change much when I added the weight on the seats above the cooler, I wasn't sure it would be worth it.

taps at 5 or 6...?

are you driving in a straight line? I like a tad bit bend..

I get no prop wash at TAPS 5 or 6, but I'd like to take it below 4 to try to lengthen the wave some.

I do try the slight turn sometimes (which I know can help with wash issues generally), but I don't know that I did that with the TAPS down. I suppose I could try that, but I don't think it will solve the issue given the amount of wash I'm getting (which is pretty significant). Plus, I don't like having to turn just to get a good wave.

Thanks for the replies so far.

What rpm are you turning? Could you hide some lead under the cooler?

Do you know what degree of list you have ? I agree with duff sounds like more weight all along the starboard side would help then you could add more to the port rear so you can get the whole boat down in the water and listed

I haven't paid attention to the RPMs while surfing. How does that affect things? I suppose I could do lead, but I'd like to avoid the hassle if possible. On the other hand, maybe it'd be easier than removing the cooler.

I checked the list, and I think it was around 10-12 degrees, but I'm not 100% sure now. Man, I need to write this stuff down at the time. We'll be out with a bunch of people in a couple of weeks, so I can really load up the starboard side and see if there's any improvement.

More weight up front will lengthen the wave as well as more speed and less Taps. More taps and Slower speed as well as more rear weight will increase the height of the wave.With the VX on the back you have 2 extra feet. So now it's like you have a 24' boat. More weight will be needed to get a longer cleaner wave.Usually 10* to 12* of list is the range. If the Tige emblem is within a inch of being submerged and the list is right you will get your best wave. We have Pro Ballast which has 2 400 pound sacks in the front. We fill both of them. We also fill the surf side rear 1200 pound sack on the port side and hard tank and a little more on the off side rear. We only have a 800 pound sack on the Starboard rear. 2 large adults or a 400 pound sack on the Starboard seat will make the Goofy wake good. I suspect you need more weight up front as well as in the rear. Good Luck.

Higher rpms makes the wave more washy. I run about 2900-3100 rpms and my wave is nice and clean. I think it makes a big difference. Hide some lead. Do you normally only surf goofy?

I think I can help you out. You absolutely positively DO NOT have enough weight, especially with the VX. Lucky for you it's not too expensive to change the front U shaped 400 sac to dual 400's. But you may not need to do that, however it would help and Tige has dual pumps and dual drain pumps already installed. I can talk you through the process over the phone or write detailed instructions on how to upgrade the front.

Now for the cure to your problems. I ran the factory 250 rear tank with an Enzo sac (1450) on the goofy side.It didn't fill up all the way due to the cooler. I estimate I got about 1000 out of the 1450 Enzo Sac. I also just ran the goofy side 400lb full in the front. There are custom sacs you can buy from wakemakers.com that will plug right into your plumbing.

Do you have a 400lb sac you can try on the seat? If not try to dig one up and put that behind the drivers seat on top of the seats. I believe this will give you enough goofy side rear weight. If it still is a bit washed out try putting more weight up front, up to 400lb.

My setup along with a goofy wave pic and video. Try this configuration and if it doesn't work get a pic of the wave and we can try some other options.

Taps 5
Speed 11.0-11.6 (Goofy side likes more speed)
Rear 250 full plus 1000lb Total goofy rear = 1250 (with a 400lb on your current setup sac you should achieve this)
front 400lb surf side (try your 400lb U shape full and add weight if needed)

I have a 2014 rz2 with vx and I have pro ballast and my wave is massive and super long, I would do more bow weight as well for what ur looking for, I have 1400 Enzo's and surf prop and my taps is at 5 and I go 10.2mph hopefully that helps but I know vx boats like bow weight.

[Surf406]

Oh yeah I forgot to add my boat is always leaning goofy to.

Higher rpms makes the wave more washy. I run about 2900-3100 rpms and my wave is nice and clean. I think it makes a big difference. Hide some lead. Do you normally only surf goofy?

That's an interesting point about the RPMs. I know a lot of people go to the 1235 prop for surfing, but that increases the RPM's, right? I have no wash on the regular side. We surf both goof and regular -- probably about 50/50.

I think I can help you out. You absolutely positively DO NOT have enough weight, especially with the VX. Lucky for you it's not too expensive to change the front U shaped 400 sac to dual 400's.

Do you have a 400lb sac you can try on the seat? If not try to dig one up and put that behind the drivers seat on top of the seats. I believe this will give you enough goofy side rear weight. If it still is a bit washed out try putting more weight up front, up to 400lb.

Awesome stuff, cday. Thanks. Do you have the VX? I feel like I've tried a lot of this (more weight up front, 400# sac and/or people behind the driver's seat, etc.), but I'll do some more playing with weight and speeds when I'm out again next weekend. I'll be there with a lot of people and some extra sacs, so I should be able to throw some weight around pretty easily. I'll report back with some pics and maybe video.

10.2 mph? I feel like when I get below 11, the goofy wake is really short and steep. I'll throw a sac up front and slow down and see what happens.

Thanks for all the replies, everyone. That's why this site is so great.

18c how 'bout you post some pics of your wave on both sides

I think we need more pics of VX waves + details on ballast
