    The old sl450 we ran a 16x13.9. 4-4300 rpms all the time with a medium crew. Our new sl we are able to run the 16x17. Usually 35-3600 rpms

    Having a prop pitch of 17 deg on the new SL has gotta be holding you back, no? Even with the 575 engine.

    (I'm assuming you use it for surfing primarily, rather than skiing/boarding.)

    We ordered it with the 13.9 prop. Since they went from a 1.5 trans to a 1.7 in 2022 it was running way too many rpms. 4200 or so. The 575 pulls the 17” prop no issues. I honestly think they should have kept the 1.5 trans

    I am free to being corrected if I miss speak

    The Makai was a new model for 2019 and I do not believe the hull has had any changes since then…. The flow 2 surf system was standard from the get go, and I believe in 2021 and up the Flow 3 system was available as an option (though may have been standard) I do not believe there have been any real significant changes to the design up until the dash redesign for 23…

    That sounds about right. I think the Hull is still the same as it only came out in 2019. It was a boat and a newer shaped hull for Moomba at that time.
