Surf tabs on a direct drive (ski boat)
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.

Thanks guys. I already read those thread (well done shoebox btw, it's awesome) but i couldn't find anything for direct drive boad.
;
I decided to go ahead and give it a try. Here is the design i will was thinking to install :
gate_1.JPG
gate_2.JPG
Attachment 27988
gate_3.JPG
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.2019 Supra SL450

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.
