As we were bringing our jetski that we just recently got, an '03 GTX 4-tec in idle speed it sucked up a rock. This is only my second time out on it and I would like to corrected this problem. I later read that the jet ski sucks from as deep as a few feet, how do i get the rock out from inside the impeller? After taking it out of the water and bringing it how i found a rock stuck in the impeller? So the question i have is can i get it out on my own, if so how? if not how much will it cost to bring it in a get it fixed, and do you think i will need a new wear ring and impeller?
