    Tested my ski with no cone

    My best was 74.3-74.4 on 90 degree weather,
    I did wirhout the cone 74.9,75,75.1 back up runs with the two back holes gone in the ride plate. I need to fill them again and see my speed rise.
    It works,
    Thanks for the free speed

    Free Speed

    Now that the word is out and agreed upon, can someone with a full grasp of what has been figured out over the last few days sum up the technical aspects of how this may make it more difficult to do work on the ski when cone is off? Thanx

    Are you seeing increased RPM's or are your RPM's the same with a higher speed?

    Brian, RPM's stay the same. Speed increases as well as acceleration, from what i can tell.

    Thanks to Mr. Kerry Hibdon for going public with this closely guarded secret

    The only thing that comes to mind is that perhaps running without the nose cone is creating minute cavitation which would lessen the load on the prop and enable it to spin more RPM's. The fact that the RPM's are staying the same is a bit of a mystery as to why the boat would be going faster at the same RPM's... Hmmmmmmm.....

    Its a mystery to me too and also to Kerry. He couldn't explain it either. All i know is it works. .7 mph for me

    Just to make sure i put my nose cone back on this morning and went out and never achieved the speed i got without it (82.9)

    Just thinking out loud here... Did you test the boat going in both directions and come up with the same .5 MPH increase?
