I sucked up some rocks that ruined the prop on a 2006 gtx 4 tech wake edition seadoo. I was wondering where I can find one used or on the cheap. also what years and models will fit that edition. I have taken everything apart and am sure thats all that needs to be replaced. any help would be appreciated, its not my seadoo and I was forced to use it to go help a kiteboarder in need. Thanks.
