    remove the intake grate and with a flash light you'll be able to spin the prop and see if its after market and you'll be able to see the pitch on the hub,, its really uncomfortable thought.

    There are markings on it. It should say 13/19 or 14/20. Also check the color of the nose cone.

    For the power loss check the wear ring/impeller housing clearence.

    Hey there Nobby

    To quickly check if the prop is standard or not..

    Lay under the ski and again shine a flashlight into the intake grate..

    If you can see a nut shape on the nose of the impeller it's almost certainly the stock one..!!

    By "nut shape" i mean where you'd use a wrench on it, and NOT a testicle..!!

    You should be able to see this without stripping anything off.??
