Is there someone that already installed surf tabs on a direct drive boat (ski boat)? I have a Supra Launch LTS 2004 boat and I would like to add some home made automatic tabs to improve the wave. Currently, with 800 lbs in the front and 1200 lbs in the back, I am able to surf but I would like to improve my wave without buying a new V-drive boat.
Thanks
Eric
Not many people looking to spend $3-4K on tabs for a boat when most d-drives can be worth 20k?
Not saying you have a 20k boat, but I do not think you will find many on those hulls.

Good for you if you can make home made ones and save the $$.

It is definitely do-able.
Here is a thread on a homemade system.

Wakemakers sells a kit.

I’m pretty sure these could be modified, depending on how handy you are.

Those homemade ones are mine. I have about $1k in the GSA-style tabs setup, or $750 with the silver, less-complicated tabs.Quote:

I decided to go ahead and give it a try. Here is the design i will was thinking to install :

Undeployed it's -15 degrees and it will go up to 30 degrees fully deployed.
I will be using the lenco 101 XDS actuator (already ordered) and i will be controlling this with an Arduino MEGA so i can hook it up to a screen and a GPS module. This way I can program some automation (auto retraction after X mph, etc.).
Since i don't want to drill my hull, i will make an aluminium structure that will be attached to the swim plate brackets. My swimming plate is very low with all the extra weight i put in the back so i will use a 2'' Aluminium C beam to jack it up and i will also attach my surf tabs structure on it.
I am from Montreal so i have about 5 months to get this done before i can give it a try so that should give me plenty of time.
Any thoughts ?
You're going to have to drill into your hull to mount the tabs, so why not a couple more holes for the actuator? It would save a ton of time and effort.
It looks great, a lot like the Mastercraft tabs. That outward angle should probably make for a great wave, since you're getting a little tab effect, and a little gate effect.
As I mentioned in my write up, I'd recommend tapping the hinge holes and use machine screws, not sheetmetal screws, unless you have access that you can through-bolt.
Does your swim platform interfere with your wake?

I did a surf system like Nautique's NSS on my Direct Drive. It worked pretty well. It was actually cost effective and I could change sides in under 30 seconds manually.

Save your money and time and use a suck gate or ghetto gate.
In fact i won't be drilling anything in the hull. The tab hinge will attach to the aluminium frame (blue in the image below) and the frame will be bolted to the swimming platform brackets.

I sent the drawing to the local sheet metal shop so they can make be the tabs. Now i am working on the arduino program and on the control box.
Yes it does, that's why i am jacking it up by 2.5''. It should clean-up the wave.Quote:

My cousin sent me a picture of a Supra direct drive with surf tabs that was on his neighbors lift. I will see if I can find the pictures.
That would be awesome!
He’s gonna take some better pics next time he’s out. I deleted the ones he sent me but I have one you can barely make it out.https://uploads.tapatalk-cdn.com/201...da5a585473.jpg

Good deal.Quote:

I used a strips of HDPE on top of the swim platform mounts.
I also swapped out the old platform for a new surf platform and a nice pad on it.

Gate received and controller programming almost completed. I just need to find some time to finish the frame and to assemble this.
My gates are finished and installed. I only need to install my controller this week and i should be able to give it a try this weekend.
Anybody know why i can’t add pictures anymore?
