    Default 2017 Supra SA 450

    I have a 2017 Supra SA 450. Our dealer diagnosed a faulty fuel pump and so we had it changed. Upon return I still can't reach surf speed and I've tried 6 different props. Currently running an ACME 2775 15x12.5. Should be tons of prop. Question, what else do I start looking at? Faulty ECU, spark plugs coils? I'm fairly mechanically inclined but I just need some new thoughts.

    I run that 2775 prop on my 2018 SL 400.

    No issues getting up to speed with a boat load of people.

    300 hours should be the service interval for plug changes.

    When at the dealer, did they hook up a computer to look for any error codes?

    Hard to fix by just throwing parts at it.

    I have a 17SA 400 and also run a 2775 and I have enzos in the back and can get up to surf speed no problem at 3500 rpms comfortably. I agree with the above sentiment. Something else is up for sure and it isnít the prop.
