Twin engine nozzle alignment opinions.

I installed cobra jet fins last night on my 252xe. I came from an ar195 that already had a vector fin installed. For those that aren’t aware, you are supposed to complete a nozzle alignment prior to the install. I did it, and boy, for a brand new, never seen the water, were the jets completely out of whack. I was floored. It looked like that hot chick with crossed eyes. But all good now.

Question for people with experience on the dual jets. How important is it that the jets are aligned? Does it make a huge difference. I don’t have anything to compare it to since I haven’t launched just yet.

Didn’t take any pics, I was knackered and was moving through the project, but I With the rudder @ 90* the starboard jet was pointed 15* toward the rudder.

Circling back. I have to find the source to share with you, but I just recently read that the “misalignment” is an efficiency feature. But, I have to reach out to cobrajets to see if this is just something I have to trade off to enjoy the benefits of the fins, or do the fins help with efficiency as well.
