    For the 2018 and 2019 XT22 & XT23 series boats, the engine options were (do I have this right?):

    5000 = 5.7L MPI 320hp

    5500 = 5.3L GDI 365hp

    6000 = 6.2L GDI 430hp

    Meaning the 6.0L MPI was not offered in those years and now in 2020, essentially it replaces the 5.7L MPI motor (the old 5000)?
    This is correct. Pretty sure you could do the 7000 maybe?

        None of these motors are obnoxiously loud.

          They’re definitely not Indmar raptor loud

            Anybody know the weight difference of the two motors?

              At Idle you can't hear it, sometime I find myself checking rpm's to see if its running lol.

                I heard a FAE will void the warranty if you install one. You could move the straps to hook in a different spot on the trailer if you needed one

                  Honestly, an FAE on the 5.3 isn’t necessary

                    The 6.0 won’t be working too hard in an NXT20 so the economy should liveable. I believe it is “5 Star” rated for emissions which hopefully means you won’t be sucking down too much CO.

                      Yeah, the “void your warranty” comment always seems to come up with the FAE discussion. I’ve never seen anyone posted an actual document that states it however. Malibu and Nautique both have “surf pipes” on their boats right out of the factory for what it’s worth.

                        I like the 6.0L over the 5.3L, noticeably more power for me. Not much but if you drive them back to back you can tell. 5.3L wins for emissions and being quieter and antifreeze cooling.

                          You can seriously notice less than 10 horsepower? Seriously doubt that

                            I should be doing a live test here soon if it will ever stop raining and putting debris in the lakes. Fuel economy on both my past 5.7's was just fine , I'm assuming the 6.0 will be comparable. X25 and X22 were both fine with the 5.7, we are always lightly loaded with 1 to 3 in the boat, can't comment on full ballast and 6 or 7 adults as we have never done that. 20 footer should be a rocket with the 6.0 motor.

                                I would gladly take the performance of my 6.0L with better emissions, higher fuel efficiency, and lower noise.

                                The new GDI motors were noticeably quiet, plus the newer/deeper bilges seemed to deaden noise as well.
