I purchased your combo for the above boat. Easy Install, thanks, it's great. I talked to Yamaha Tec. Support, and the person I talked with said she has been constantly hearing about your product but d...

I purchased the SeaDoo Jetboat primarily because the waters here in Bradenton are so shallow. Jeff put on the steering mod and the handling is so much better. It has maneuverability at idle whereas be...

Hi Jeff - I installed the Cobra Jet Venom Ultimate fins last week. The difference in handling is night and day. Prior to the installation, my 2014 Yamaha SX 190 was very hard to steer at low speed bec...

We received the steering fins this afternoon. I installed them and took the boat to the lake. They made a huge difference in the slow speed steering. I will tell others about my experience. Thanks aga...

Jeff, sorry I didn't get back to you sooner with feedback I have been too busy enjoying the new boat. The Cobra jet steering fins have made all the difference in the world to the 2012 Yamaha AR190 in ...

I am the individual who allowed my 2004 sea doo to be photographed and displayed on this web site. I consider myself to be a serious jet skier and have been for nine years. After purchasing my newest ...

Absolutly fantastic!!! It was like having power steering. It does everything it is advertised to do and more. At full speed before it was installed, it took some force to turn it. Now I can turn using...

Rick Hopper
Fins are working great! Wow, what a difference. Install went smoothly. I would recommend the fins to any jet boat owner! Thanks Jeff!

So after a couple of months of going back and forth on whether to buy Lateral thrust reversers or try a new system all together we went with the Cobra Jet Viper NK's with Mega Fangs (can't really go w...

I have a pretty quick, modified XPL Seadoo. The design of the hull makes it unpredictable in chop. I have extended aftermarket sponsons and I tried your standard steering system along with the sponson...

After doing some research on my boat before I purchased it, I came across the Cobra Steering System. All I can say is WOW!!!. This product does give you a better feel and very quick response from the ...

I have the CJS venom viper kit and I can assure you the kit performs exceptionally well. The attitude of the boat is completely changed on plane. It cuts through the water rather than on top. No mor...

Been meaning to chime in and tell you guys how awesome the Viper unit is. I now have 2 seasons with the 16 192 and wifey has only driven once for literally minutes. She just keep saying I can't keep t...

All I have to say is THANK YOU!! I was going to trade my boat in and your fins made all the difference in the world!! I was scared to drive my boat without these, now I can control my boat and dock it...

I can't say how much I enjoy your product ,excellent all around slow, fast, docking or pulling, just great engineering and fabricating thank you so much!

It's hard to believe that such a small incremental expense can drastically change the overall performance of the entire experience. I am not a professional rider, in fact this is my first ski. I had i...

Just when I thought that great product, great service at an affordable prices was a thing of the past, then I found Jeff. The Utopia 205 is one of the heaviest seadoo jetboat and it needs quite a bit ...

We are senior citizens and decided to purchase a jet ski to help entertain our grandchildren. We purchased one with the Cobra Steering from Jeff. It is unbelievable! Now my wife wants her own. The ste...
