    Welcome to the forum...

    First things first a few questions..!!

    How did you record this speed.?? GPS or stock speedo..??

    How many RPM's are you achieving..??

    Do you have an aftermarket tach..??

    Is the rideplate box stock or modified..??

    From Who or how did you get the impeller to 14/21..?? is it a dynafly..??

    With the heads what compression are you seeing..??

    What EFi settings are you at..??

    Which Grate 800 or 1200..?? (manufacturer..???)

    Reed stuffers..??? (??????)(shame you were there far into the motor and kept the stock reeds in there..)

    There's loads more questions to be answered to get a better picture(idea) of your ski/issues..!!

    Welcome to the forum CoaCH!!

    Really not to bad of a speed all things considering.

    Get a Tinytach from the online store and figure out what this thing is doing. To many variables without knowing the real RPM.

    Is the pump shoe sealed?

    Tunnel reinforced?

    Can you take pics of the rideplate and its relation to the shoe on the boat?

    Where ya located?

    okay...So..Who pitched the prop again.?

    How was pitch measured.?

    Find out your RPM's with an aftermarket tach.

    Speed doesn't sound very off from where you supposed to be at.....
