Worked awesome. Still working on my tie down technique but it def helped the wave considerably.

High quality. Very happy with it.

Looks like you also installed TVs on your 255XD? How are they when the wakebooster is deployed? Any issues? Just got my 255xd (my first Yamaha) and I’m reluctant to install TVs without feedback about how they interact w/ the wakebooster.

I installed Cobra Jets as i wanted influence at speed also. Im still in testing phase.

While i love how the boat performs with the CJs from a steering staindpoint only, im interested in also not dimishing its surf capabilities either.

The wake booster deployed directs water, (which ive verified by surfing behind the boat and watching the transom) right at the outside fins. It hits them and directs the water a lil different then what Yamaha intended. Did it ruin my wave? No....but i know its def impeding the boosters usefulness. TVs i would think are much worse with this as they are longer and also rotate directly into the incoming water path from the wake booster. The CJs i can adjust by moving down the fin further into the water and not into direct conflict.

Another thing to note is the CJs and the TVs also force you to straighten the nozzles. Does the booster work as well with the nozzles straight? Im not sure, thats why im still testing various setups and noting my findings.

So far ive tested CJs on and all the way up as per Jeffs suggestion if i kept the Surfpointe canted settings as the fins would only work at low speeds and not cause drag once beginning to get on plane, as a fin severly toed out in the front would just cause drag and make the boat struggle more, on top of the canted jets which take a lil thrust away while trying to move the stream into center of boat.

Ive tested straight nozzles with CJs all the way up, and thats where i saw the most conflict with the wakebooster water stream.

Ive now moved the CJs all the way down, to be the least intrusive to the wake boosters water stream and my nozzles are straight current. Going out testing this weekend.

Reason im hoping the straight nozzles work better and the CJs down not interfering little as possible is the boat needs a lil more thrust with all this weight im adding to the boat. I have the 25ft fatsac 850lbs, and have had to put almost 350lbs up front with only 2 on the boat and 1 in the water cause the boat had a real hard time getting up and starting the wave. Im also going to be resealing my pump tunnels to remove as much cavitation as i can.

A win win will be gaining the gas mileage and thrust from straight nozzles, while allowing the booster to do its job without fighting another flap in the water and having the steering enhancement the CJs provide both slow speed and high speed. The boat was awesome with the cjs at speed! I may even trace Jeffs shape on a sheet of aluminum i have here at shop and alter the top shape to completely be out of the wake boosters intended water path.

Photos provides are CJs up @ setting 5 vs 8

Thanks for the quick and comprehensive response. You have confirmed my decision to hold off until there is consensus about the best set up.

im no expert, but looking at the pictures you cant tell me it doesnt NOT interfere. Right? I also verified behind boat. Is it enough to ruin? NO we went ropeless in all instances even in 6-10ft of water BUT...i want the cleanest wave possible.

Have you had a chance to surf more with the CJ's installed. I like your idea of trimming the top corner. I'm thinking of ordering a set for my 255.

Not yet, im also going to trace the outer fin shape and make a modified set to test with also while im waiting to get back in the water.

Just to clarify, that on our AR250, with CJ fins and Wake Booster. No ballast, wake is shaping up really well, and the kids and wife can all surf rope less. The board is key, we are using the Hyperlite landlock. 5'9". The other boards we tried so far, no go for rope less.

Me only occasionally. I need more ballast. (I'm 6'5" 265lb)...
I've ordered the transom bag, hopefully will have more pic's soon.

Just curious if anyone has had more insight on using CJ with the wakeboost system? I also have a 255XD and haven't found a thread with any definitive results on whether they impact the wakesurf wave or not. I'm leaning toward getting a set of CJ's to improve the slow speed tracking and high speed turning but since it does well enough on its own, I don't want to ruin the wakesurfing ability.

ive modified my cjs.

Moving the jets back to straight def impacted my wave quality. The whole purpose of the wake booster is the knock the jet away from the wave face. Also with the cjs the directed water from the wakebooster was hitting the outer fin causing another disturbance. I made a new set of outter fins and trimmed the upper portion so it didnt interfere with the boosters water flow. I then put my nozzles back to surfpointe angles and ran spacers to make sure the cjs were perpendicular to the back of the boat (straight like the articulating keel).

I plan on over the winter designing something to do away with the spacers and have an adjustable pivot on the outer fin so i can easily set the angles and lock down.
