Bad jet pump/impeller bearings?
1999 GTX Seadoo
After getting a quote from a local mechanic, I was not willing to pay $1200 for a jet pump replacement.
Basically the compartment filled halfway with water one day on the lake. After I drained it I tried starting it again and heard a LOUD screech from the back...I mean ear piercing loud. After I took it out I noticed the cone to my impeller was missing. Obviously the impeller was not getting any oil through it. Would that cause the loud screech? The area where the cone covers has some rust and the impeller will not turn at all by hand. I realize I may have a couple things to replace now. Anyone have tips on how I should go about this? I am pretty handy so I'd rather not take it into the shop.
Also wanted to add...the seadoo would crank for about 2-3 seconds while pushing the throttle. Then the loud screech would come and the ski dies.

I just recently rebuilt the jet pump on my friends 00 GTX. It's a very simple process. Order a rebuild kit and get to work. Just need to press in the bearings and it sounds like you need a new cone.

I was thinking about it and you may need a new impeller shaft.

Yep! Got the impeller and drive shaft out. She runs great. At least I know it's only the impeller now.
Ordering the replacement parts today or tomorrow. I estimate around $180.00 needed if my impeller shaft is out too. I'm going to order the tool first to make sure the shaft is bad. Think I can use the same impeller blade? It's not THAT dinged up. Just a little in one spot. Thanks!
