Stupid question about a TZX 190

[Sivart]

What is the difference between a TZX 190 and a ZX 190?
I currently own a 99 model SX 186 with a V-max 150. I love this boat but want a little more room and storage. I have a relative that has a ZX 190 and it is exactly what I am looking for. I am currently looking at a 2003 TZX 190 with a V-max 150 HPDI. I really have no clue what the T stands for.
I have never GPS'd my SX 186 but by the speedometer It will run almost 60 mph with a 23 M prop, can I expect the same speed with the TZX 190 with the V-max 150 HPDI ? It does have a 10" jackplate.
Thanks in advance for any help with my questions.

I have the TZX190. It is the same hull as the ZX but it does not have the touch pad buttons on the dash and maybe a couple of other small cosmetic things. Set-up right with the correct prop you can expect 61-62 mph. I have done a lot of prop tweaking and testing and mine with the 175HPDI will run 68+ gps with just me and a moderate load and 66+ with 2 aboard loaded to fish. Hope this helps.

from my understanding, quoting from a dealer the TZX, was the same boat as the ZX, just changed the name for a couple , few yrs, ...."its the same boat"

As Bass Junkie said, it is the ZX with analog switches instead of push buttons. It was not simply just a name change.

If I remember correctly, the pre tzx boats did not have buttons either. I was told by a dealer ..."same boat as last years, they added the t to stand for tournament..." When they added the push buttons they went back to zx. I guess it was a way to upgrade the larger zx boats and differentiating them from the the 200 or 190 model.
