I have finally seen it but it is still spinning on here but I have been fighting with you tube all day I agree that believe the cut out should have been so thanks for the heads up everything is on correctly I will make the adjustment on the parts. However adding a second washer would work if someone else runs into this contact I will check the inventory and change it.
And as for the reverse thrust with the side thrusters did you do a test with the boat stock I recall you saying that you tried it stock between the two fin test videos, I would think a that would be a good base line for comparing the effect of the various systems influence. I recall the look on your face when you put my mega fangs into reverse and hit the throttle. So I know those worked . I would have loved to se you doing some fast turns under power at 35 mph or so just for the look on your face.

ok that helps can you show me a close up of where the tie rod attaches to the nozzle

I tested the reverse with no steering system installed. The reverse with either the JBP or the Cobras was greatly improved. In that aspect they are on par with one another. The Cobra's reverse was slightly stronger when turning as 30% of the thrust is being redirected with the JBP system. The JBP system does have a tighter reverse turn.

I did do a 45mph 360 degree turn with the Cobras. It is in the video.

I am going to do a comparison video with me babbling about the two.

ok I appreciate your efforts.

I just added the lateral thrusters to my boat which has Cobra AK's with the original small fangs. Everything seems to fit with no interference whatsoever. I'm in the north so won't test until probably April. I liked the improvement the AK's provided, but do get frustrated not being able to kick the stern over without the bow pivoting out ( old time exposed prop boater). I am hoping the hybrid combo of add on's will give me the handling I am hoping for!

@PeterB , please post some pics of your current set up (I.e. cobra fins, fangs and lateral thrusters).

@PeterB , please post some pics of your current set up (I.e. cobra fins, fangs and lateral thrusters).

For clarification the fang he has is the original one for the magnum A K steering NOT the Mega Fangs If he would have upgraded to the mega fang set he would be adding even more steering influence in all ranges increasing the level of power steering, increasing the reverse thrust for better stopping power and obtaining the enhanced reverse control he was looking for, all that benefit at half the cost of the parts he did install, That being clarified he did install that system on my magnum A K steering without the MEGA FANGS as I stated, those would be in the way due to using the bottom base bolt of the nozzle. Note that @swatski changed from the original single fang to the set of Mega Fangs and experiencing a huge difference in the areas I just mentioned as I am sure others will also be sharing their results as time goes on this spring.

The Lateral Thrusters seem to fit well with the Cobra AK's and the older Fang add on. The Thruster port is open when reverse thrust is directed to that LT. When turned the other way, it is blocked by the fang, but there is no thrust directed to the LT in that position. I'll test as soon as I can get on the water.

Also because my steering is adjustable you could actually move the fin bolt to the second position and move the fins and fang back more.
Just for accuracy this picture has the mega fang setup but if you look at the fin you can see the bolt is set on the second notch not the top notch so the fin is back further. If it had the regular fang attached to the fin this would also be back further.

What's with the dislike @LakeTravisBear ?

Could have fat finger syndrome, I suffer from this...lol

This raises a question if you don't mind pondering this point, we have a 5 mph variance and you also ran with no extra system on the boat totally stock. I was wondering if the 50 mph top speed remained the same running stock it should have and that only leaves one loose end. If you reinstalled the thrust vector steering and checked the top end again. This would certainly prove my suggestion about the 10 hour break in causing the difference or disprove it.

Jeff,

There has been a lot of talk of having Cobra’s and lat thrusters together on the bigger boats how about on a newer 19’ with a ruder?

 

[Cobra Jet Steering LLC]

Well as you know I always tell it like I see it. And I am glad you asked me, I actually believe I was addressing this and other questions in my alternate side force stabilizer thread before it was shall we say derailed.
The 19 foot boat with a rudder can not use my mega fangs and I am assuming you already know this They can use the Ultimate steering and with the new setup I have on hand that allows you to co mingle the lateral thruster and my Ultimate steering there is no mechanical conflict whatsoever . Actually removing the rudder during the install process of the lateral thruster makes installing my new side force stabilizer very convenient.
Now I would caution anyone from doing this until you get feedback from several people that the lateral thruster works sufficiently to make it worthwhile. Will himself has said that it won't be as effective as the twin engine setup and we have seen that the twin engine setup does loose reverse thrust with the lateral thrusters installed , After spending a lot of time researching the part I believe it will actually take even more of the reverse thrust away from the single engine system and I am not being critical just being up front. I want you to do it and if I didn't I would not have invested all the time and effort in designing compatible side force stabilizers to accommodate it. So I will see about posting another picture of the special setup for those single engine adaptors.

With the rudder off during the install of the lateral thrust part you remove the bolt on the nozzle end, insert a double ended 10mm bolt into the rudder control retainer then by hand install that from the bottom turning it until the end of the bolt protrudes through the top of the nozzle casting enough for you to slip the new side force stabilizer on to it , then continue to turn it until the top protrudes past the stabilizer enough to place the 10 mm nut on the bolt . Now continue to hand tighten from the bottom when the rudder retainer is close to being snug tighten the 10 mm nut with a 17mm wrench , align the rudder retainer so that it is facing forward so when you complete the other part install the rudder is back in place and that is it.

With the Twin Engine Lateral Thrusters installed and the steering wheel dead straight no reverse thrust is lost. If the wheel is hard over then 1/6th of the total reverse thrust is diverted laterally. On a single engine the same is true except that when the wheel is hard over the reverse thrust is diminished by 1/3rd. That 1/3rd reverse thrust is diverted laterally. If the steering wheel is dead straight there is a negligible (practically non existent) loss in reverse thrust on the single engine models.

 

[swatski]

Well, what is also true though - with the twin MEGAs installed and the steering wheel dead strait the reverse thrust is multiplied (as compared to stock).
I don't know how to "measure" those effects - but those are VERY tangible/significant.
