I have a 2011 sea-doo gti 130 with only 10hrs. I was leaving dock in a new lake i wanted to explore. I got about 20ft away from dock with kids and i sucked up a bunch of rocks just idling away. I shut it off right away. I then restarted still.made noise so i shut it off again. Swam jetski back to shore loaded on trailer. Pulled a dozen rocks out but i have about 3jammed in impeller and wear ring. Any advise. This my first wave runner
