Did You check your nozzles with a straight edge? the non tie rod nozzles can be set towed in slightly using the steering cables adjustments and yes you may need to unbolt the springs, but that is pretty simple to do.
I always recommend some thread lock on the bolt when you reinstall it if you do remove it.
If your nozzles are even I would not do anything unless you experience a pull at high speeds ,remember your nozzles setup does have a bit of side float in it and without the duel tie rods to secure the nozzles positions I believe it may require a periodic readjustment as the cables get some play.
So I would wait until you drive the boat to see if any adjustment is needed.
Not sure if your boat has trim tabs added but if you don't have those you may want to change your side force stabilizer to the latest one I am making to give your boat a better hole shot and more stable ride in chop.
I extended the ride plates out behind the boat on 2015 year models or newer. Since your boat did not have the tie rod setup yet I am assuming you have the super ultimate twin with the mega fangs.
I made extended side force stabilizers for the nozzles that have the boss on the end, I also made some special ones for adding the top inner fin to the magnum AK and AK-19 systems, So far I am hearing back that the wake is a bit cleaner the planing is very quick and the bow is more stable.
I put some pictures on my vendor section
https://jetboaters.net/threads/basic-information-about-the-various-options-from-cobra-jet-steering-llc.16857/ and I finally have fangs for the single engine 19 foot boats with the Keel as well as the AK-19 VIPER and some top fangs that are also available for ALL vipers.
I have been waiting for more inventory but I just received an email saying my parts are ready so I have been working on making install instructions and I do not have these options on my web page yet because I don't do that page and I give up on trying to get it updated, and most people know to just email or call me for info.
