:dunno: I have had some problems with my ski where while i was not useing the throthle the ski ran fine then when i gave it gas it shounding like something was slipping. I took apart the back side of the ski and found out that the prop had been stripped. i have all the screws out and all that is left is the prop and the housing. Yet i can not for the life of me get them apart any ideas? As well as any place where i could find a new prop? Thanks for your time and help!
