Did you try and search the forums here? There are many, many, many posts regarding this topic and information. Too many to list. A lot of good reads.

I'm doing that now. Pros and cons for each. Tough decision. I guess it boils down to if I want steering assist throughout the entire speed range or just at low speed. Info notice at speed it takes about 1/3 movement of the steering before boat start to turn.

There’s many factors. Cost, ease of install, your intended use, etc. For me, I only wanted help with steering at low speed for docking and trailering so I went with TV. Other people want different steering at speed so they went for cobra. Both are good, just different use cases.

Pretty obvious that these are night and day different!
For your boat I will tell you what you are adding if you choose my system lets say the most popular set for your boat is the super magnum AK-19 deluxe system.
First it just bolts on.
Second it does not effect your factory warranty, and we never have you remove the factory standoffs from the reverse hoods.
Third this patented steering system also adds a PATENTED second tie rod for balance and redundancy.
Fourth the fins are tempered aluminum , never any plastic.
Fifth they do NOT hang down below the factory rudder and keel so no issues since they do not increased draft of the boat.
Sixth you have super fins with adjustments so the high speed influence can go from none to super just by where you set the fins as only the part BELOW the Nozzle is making contact with the water on plane. However when the boat is off plane ALL the fin surface is in the water for super steering in that mode forward and reverse.
Seventh there are also top fins for even more slow speed steering influence that are also not in the water on plane. And do not have a tail hook shaped cut unto them either.
Eighth They also have the plaining surfaces to improve the hole shot of the boat , to help stabilize the hull in chop and to produce a cleaner wake behind the boat for watersport activities.
Ninth this is also compatible with the new style of AK fang for a mild power steering effect.
Tenth the steering system is able to be set to allow you to make much faster high speed turns with less speed bleed off haa just ask @swatski.
Eleventh the system when set properly will allow you to make turns not only with power or while reducing power but even with no power, helps with picking up people in the water and avoiding the tow rope.
Twelfth is the ability to steer in rough conditions and hold the bow of the boat to cut waves precisely in wind and strong currents.
And the bad Thirteenth if you allow the wife to drive the boat with this system added you will be sitting in the passenger seat a lot . go do your research but be careful of people wanting to talk secretly because I have no problem posting for everyone to see and after 20 years of blazing this trail I am proud of the impact I have had on the jet boat world. Jet boats were a declining market when I got started making them steer and making drivers smile. Remember this is just one of the model specific systems I design and manufacture for all the Yamaha jetboat lineup from 1996 models to current models.

I verified with my dealer that both Thrust Vectors and Cobras would not void my warranty. No matter which you go with, you won’t lose your warranty.

Yes that is correct and I have said that all along year after year but I think you misunderstood my message regarding warranty issues first I am stating that my systems do not void your warranty because I have so many documented situations where people claim to have been told by my competitor that my steering would void your warranty and there are plenty of posts over the years explaining the Magnuson Moss act on after market parts and voiding warranties those even go back to my competitor trying to prevent people from mixing my parts with his , but this is all before your time here.
Latest one to my recollection https://jetboaters.net/threads/cobra-jet.28908/page-2#post-502070 plus I have a file of customers who confirm this and other statements like the steering will rip your pump off I like that one especially after the wake steering fiasco with the fins magically bending the bolts during use even though they claimed that they were not in the water at speed my opinion of that system was they were the EDSEL of jet boat steering https://jetboaters.net/threads/thrust-vector-wake-update-deflector-lock-torture-testing.20861/#post-355768.
In any event I was confirming that my parts will not void the factory warranty and also pointing out that if you remove a factory part say some stainless steel standoffs from the reverse hood and replace them with different aftermarket parts should the E series reverse or any reverse for that matter fail to operate properly, Yamaha can refuse to cover that repair under the warranty if they can show that the aftermarket part caused their part to fail. But no they can not void your warranty completely. Hopefully this clarifies the point of the warranty statement.

Appreciate the clarification. After dropping as much money as I did on a new boat, I wanted to make sure any mods I did would keep my warranty intact.

I am fairly new here, but I quickly observed that there was obviously bad blood between both steering system vendors for reasons unbeknownst to me.

Spoke to Jeff today and ordered the deluxe for the 195S. They shipped today…. So maybe by The Weeknd they will be here. I like the idea of aluminum fins along with being able to select anything between low speed only to full time even at high speed. I also think that anything would be an improvement over the factory only handling at low speeds.

I’ll post up after install and again after testing.

Jeff said if I wasn’t happy, send them back for a complete refund. The guy gives out his home phone number! IDK how good they are but he sure stands behind his product. I am looking forward to the improved handling.

Just installed them yesterday. The delay was on my part, I received them shortly after the order was placed but I have been busy with other things. Taking them out today, if the weather holds up or tomorrow if it doesn’t. I like the simplicity and the install. Had one slight problem but Jeff was able to help me correct it.

Ok, so, I was able to test today. Coming off the trailer at this ramp was tight, no dock or wall next to the ramp, wind and current in the same direction. The new deluxe was better than great. I unloaded a new boat, this one actually responded to inputs from the wheel. My wife and I spent the rest of the day with grins on our faces… and then I realized I may have forever lost the captains chair and now get to ride along on the port side…..

My only question is: why are these not STANDARD EQUIPMENT on all Yamaha boats? It’s just so much better with than without. Thanks Jeff!
