I would be worried about lateral stress more than anything. Keep us posted

I took my 190 w/Ultimates (largest fins?) to Bimini and back - riding as hard as it gets really if you think of it. Not even a suggestion of a problem.

Did you use nylon hardware?

He's still alive isn't he? so I would guess it is safe to say NOPE!
what lateral stress???
I found this view of the speed in a 180 degree turn with only a slight bleed off of about 7 mph totally boring I do them at 62 mph and hold on with only one hand standing on a ski. not sitting in a seat and I do it in 6 inches of water aimed at the mangrove trees with about 1 or 2 feet to go before I turn , BORING!

Yes there is a saying I think of every time I decide to do some dangerous tricks on my ski.
You will know your limitations the second you exceed them!

Just a picture to confirm what most people know. The Magnum AK's fit with the Jet Boat Pilot Lateral Thrusters. I don't want to hear how one is better than the other or I shouldn't do this. Save it.


View attachment 70343

I actually really like the idea of the nylon bolt, I know its been said that the bracket is built to bend and take the force of a strike on the fin but if the nylon bolt holds under normal operation I think this would be an improved safety measure. My only concern would be its ability to take the lateral force and if it did give way it would put a lot of stress on the "hinge" bolt. To that concern, I was thinking, one could create a U shaped metal piece that would slip over the fin and the bracket and the nylon bolt would go though the U shaped piece, the bracket, the fin, and then out the other side of the U shape piece. All lateral force then would be on the U shaped piece of metal and the nylon bolt would only be tasked with the upward force of a strike. Just a thought for what its worth. If I end up going with this setup I may try that.

I will say it one more time never try to fix a problem that does not exist. I have been making magnum steering for many years , I have NEVER had a single issue with anyone damaging a single nozzle while using this design. I even took the time to smash a fin with a 2 by four to prove this is not nor has it ever been a problem . So if you ever do replace one of my stainless bolts with any inferior bolt do it at your own risk . I have advised you to never do it!

So, I write software for living. I know, nerdy, but it pays really well. Anyway, while writing I not only take into consideration known issues (problems that do exist or have happened), but also things that could happen. Right here on this forum someone posted about hitting something in the water that resulted in their Cobras binding their nozzle(s). Obviously, what I am talking about is within the realm of possibility.

I have customers provide feedback on all kinds of stuff all the time regarding my product. Even when it appears nuts on the surface, I still listen and take a look because I could be missing something where the feedback all of a sudden makes perfect sense. What I am suggesting is not crazy. I have never made use of the airbags in my truck, but I am glad they are there.

What I am proposing may not work. I have not tested it yet because I am waiting for the weather to warm up. Unless you can swing a 1400 lb log at 45 mph, you haven't really tested what kind of damage can be done. Now I don't plan on finding a log that big and hitting it, but I do plan on stress testing the nylon bolt under normal operation to see if it shows signs of wear. I do know this: that nylon bolt will break before the stainless steel and aluminum components do. That is useful and prudent. The only question is if it is feasible. I will let everyone know the results after I test it.

Until then, here is a list of impossible things to consider:

- a compartmented ship never sank, until the Titanic did
- your Experian data was unhackable
- the Fukushima reactor was too well maintained to melt down
- Lord Nelson claimed nothing new was to be learned in physics. Then Einstein showed up.

If he hit his cobras - he must have hit something else on the boat as well.

I'm wowed we went from damaging the pump and nozzle to locking up a reverse hood on a e series boat when they hit something and the bracket bent but no damage was ever done to the hood or nozzle . Ok well why don't you take up another hobby.
I actually saw that post and I know you won't believe me but the members here who purchasd my magnum a k steering can tell you that I advise them if they have a e series boat to reverse the 6mm bolt on the fin so the button cap is inside toward the ribs of the reverse hood and the nut is on the out side so if they hit something the nut won't lock up the reverse.

Here is the info regarding this from my emails when I send people their tracking numbers


"Here is a link to the installation instructions in color, for the ak steeringhttp://cobrajetsteering.com/media/attachment/file/i/n/installakseries.pdf

A grey scale set of instructions will be in your package also. you will find a package of thread locking compound included with the mega fangs please follow the instructions when using this product.

On the bolt that holds the fin to the angled bracket " small 6mm with nylock nut is shown in the instructions with the nylock nut on the inside between the bracket and the reverse hood you should reverse that and place the bolt inside and the nut outside for extra clearance of the reverse hood . The bracket is made to give if you strike a solid object, if the nut is on the inside it has been known to snag the ribs of the reverse and make it drag going into reverse, In the event you do strike some object during use you can usually push down on the fin and straighten it out, the bracket is not tempered for that reason and it can be bent back down numerous times with no issues."

Imagine that there goes your credibility down to a new low I was doubting it could get any lower. but I guess you showed me. Now folks yes I am enjoying this.

I don't think you are in the minority there, there is always someone trying to stir the shit up. Personally, I find those kinds of posts unnecessary.

I like reading @Foobar posts and, like him, I enjoy modding the crap out of my boat. If he "wants to paint cock and balls eating a Happy Meal on the side of his boat" he can do whatever he damn well pleases.

The most prolific and beneficial experience often is not in actually achieving something you want, but in seeking it. That's why I have my boat and I mod the shit out of it. I have not received any calls from Yamaha telling me not to, yet, but if I do I will tell them to go jump in the lake. As far as the aftermarket steering - I happen to think that you're right, but it is not like nobody else can face it. Like I said, for many of us here it’s the journey that matters — it’s all about meaningful pursuits and what you learn along the way.

I second that sentiment. Not sure what I stepped into here but I'll slowly back out of the room. I deal with BS like this between people at work all the time and I don't need any part of it in my hobbies. As parting words I'd say, most of the great and innovative ideas that have come out of the groups of people I hang out with have usually followed a whole bunch of really stupid initial ones. That's the fun of it. "Seems like a pretty stupid idea but I sure can't wait to watch you to try it." lol

Wow @swatski you probably know me better than any one or I thought you did, but perhaps I was wrong. I always give you the honest answers to any thing you have ever asked me, but you ASKED first.
And I always went the extra mile to help anyone who needed it yourself included and you know that too. It isn't about liking or disliking someone with me it's about the truth.
This man as you yourself said is apparently full of himself and trying to reinvent the wheel so to speak , making one incorrect statement after another.
Someone who could have asked me any question at any time and he would have been given the straight answer without hesitation. As he himself knew. So shame on you that you of all people totally missed the entire point of this. it is not about any agenda with me.
It's about accuracy and I am enjoying it because I could have told him how to accomplish what he wanted to do in a few seconds but that is because I have so many years of experience with these products , the magnum ak was derived from the magnum and that was derived from the cobra venom 16 x before that and there was the magnum plus in there before the ultimate was born and I enjoy this because I actually did the exact thing he was talking about several years ago in the first versions of this system. Let me clarify that NOT exact I would never use a soft fastener but I did incorporate a way for the bolt to release on impact .
Then I realized it was not the best way to go for the reasons I already explained to him in previous posts, so he did what he has done previously and just ignored what I told him about everything he asked so he has to learn the hard way I guess no big deal.
But as for you I am so disappointed in you . Really . I thought better of you . shame, shame, shame How can you think a person with 3 patents and a fourth one pending 16 years of modifying peoples boats to help them enjoy their time on the water could be trying to stop someone from modifying their boat in any way.
You sucked that nonsense down hook line and sinker but that was his garbage not mine.
I have a responsibility to my customers to point out things that could cause them issues or be a safety concern like you doing the 180 turn to the right at 52 mph and hurting yourself, if you do things like that you can actually end up rolling your boat, all it takes is one wave to flip your boat.
I love the wild stuff so I get it but I also do not want anyone thinking it is ok to do it and that you don't need to plan it out and pay attention to what you are doing to avoid being hurt.

In this case the fins should never be allowed to roll up too high as that can lock up the entire steering system if the fin gets lodged in the deck or rolls back and gets in by the pump housing although this is very unlikely I want to avoid it .
If the fin is allowed to break free on a minor impact the chances of this happening go up tremendously so I eliminate it because it is the prudent thing to do.
If I saw some good advice I would praise it but so far that has not happened and I would suggest running things by me first rather that jumping off the cliff recklessly as I have observed more that once. So Now I hope we set the record straight .

It seems to me in the event of hitting something with the fins I’d rather have them solidly bolted on. Wouldn’t it be better to have them bend vs flopping around and doing more damage to other stuff?

Or am I missing something?

Hmm. I'm not really sure how to respond. Frankly, I would rather not, but I'm not trying to hide either so here are my thoughts:

I consider you as a mentor here, who's contributions to the field of jet boat steering warrant only extremely positive comments and are, basically, unparalleled.

I would like to continue general discussion of steering enhancements in this forum without getting personal. There are two circumstances that lead to arrogance: one is when you're wrong and you can't face it; the other is when you're right and nobody else can face it. I would like to believe that neither is the case here.
