Hurt motor again????????
I just picked up a friends hurt 03 1300... I rode a couple times a week with my friend an this ski an outta know where one weekend last fall he hurt #1 piston. We thought it couldve sucked some water up since it dident have the tube on so we pulled the motor an looked at everything an sent the cylinder off to be fixed. We reassembled everything an got out on the water last week which sounded fine for about 5-6 minutes while it was out on the water while he was just verying low RPM's trying to get the rings to seat in the thing dropped RPM's agiain an died then wouldent start. We pulled a plug an it was grey meaning it something was hurt..... Do you guys have any idea what could keep causing this? Maybe clogged up oiling? Bad Injecter? Again the ski never saw more than half throttle and was out maybe 5-6 minutes :-/..

If its the same cyl then there is another root cause. It could be an oil line, an injector, an air leak, a crank/seal, etc. After you repaired the engine and didn't find a root cause (you only suspected water intrusion which usually happens on #3) did you air test it to verify there were no air leaks?? I would consider that mandatory without a root cause being found.

I never thought about an air leak... How would I go about testing for that?
