I installed Cobra Jets as i wanted influence at speed also. Im still in testing phase.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.
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.Thanks for the quick and comprehensive response. You have confirmed my decision to hold off until there is consensus about the best set up.
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.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.
ive modified my cjs.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.
Jeff i think you need to slow down here with all the patent talk and lawyers. I BOUGHT YOUR FINS.Sadly you can not make your own fin modified or not you can make the additional modification and add it to a fin or change the shape of the fin but in order to do what you did even for your own use you have to get a license from the patent owner of the original fin and the fin must be purchased or licensed from the patent holder.
The way lawyers explain it, if I patent a pencil and you invent an eraser you can not sell the pencil with the eraser attached.
My suggestion would be to purchase a fin and make the changes to it add what you want and make changes to the top etc once you purchased the original fin you can do with it what you like.
But you can not make your own so that is it in a nut shell but don't take my word for it ask a patent lawyer.
Also I am required to say cease and desist.
I know most people don't understand this so please discuss it with a patent lawyer I have no problem discussing licensing etc but I have a lot of money invested in my patents so I must protect them. I hope you understand. I welcome a discussion on this . Also I just looked at your pictures again and if you wanted to use a fin below the paining surface just by a top fin and reverse mount it so it is under the plaining surface rather than on top no mod required just mount it on the outside of the nozzle in place of the super fin upside down!!
I cut it to make it level with the planning surface. With them unaltered and even at the lowest settings the wakebooster water flow still smacked into the fin. Like i said im trying to clean up the wave as much as possible.new to the jet boating world. but quickly learning exponentially from you guys. awesome write up.
any updates? how many inches did you remove from the top? or your goal in mind was to make it level with planning plate(that was enough to remove any disturbance)? also, when you say you went back to surfpointe angles, you mean pointing your nozzles inwards by 1/8 turn from center?
very curious how you are going to keep the outside fins perpendicular, maybe using a mini turnbuckle type of mechanical device?
do you plan on making the inside fins perpendicular? or is that moot?
