my buddy ran over the ski rope with my 97 gtx shot through the impeller and shredded the rope. We shut it down immediately and pulled the rest of the rope out by hand in the water. i got on the ski after that and turned it wont move faster than idle!!! even when i floor it, the engine revs all the way but it just wont move!! i took the whole rearend apart and took the impeller out. the only thing i see that looks messed up is that the impeller plates are a little bent up....not too bad, but they are bent. would this bend be enough to cause this problem??? any and all help would be appreciated. thanks.
