2002 GTX RFI can’t plane out

[CoolHandJohnny]

I’m new to PWC’s so I don’t know a lot about them. I bought a 2002 Seadoo GTX RFI with the 787 motor. The first time I went to the lake, if I was on it by myself, I could get it up on plane and it was fast. If I had a passenger, it bogged down, lost power and would not get up on plane. I took it to the shop. It needed a new wear ring and the power valves were completely froze up. They tried and tried to get them out but ended up replacing the cans and whole assembly. Long story but they ended up putting a rebuilt motor in it too. Took it to the lake today (first time since out of the shop) and now it won’t even get up on plane with just me on it. The rpm’s will get up to around 5,000 but will not get up on plane. Any ideas what this could be?

Check that the ravs are working,,,,put in new spark plugs…do a compression check if needed.

My son said when he tried it a warning message came up about voltage but it only showed up one time.

What's the condition of your pump, wear ring, and impeller?
EDIT: I guess if you're new to PWCs, you should know that the jet pump is the thing that provides thrust to move. If the impeller is chipped or damaged or there's too much gap between the impeller and the wear ring that surrounds the impeller or if the wear ring is damaged, you'll get cavitation, which reduces the efficiency of the pump well below what is needed to plane.

Wear ring is new. The shop replaced the oil in the pump. The impeller looks perfect. I can’t see any nicks or anything in it.

Link to video

This is a link to a video I had my son take of me trying to get it up on plane. It just wouldn't do it. Got the RPM's up to around 5,000 a couple of times. This was taken after trying a few times, letting it idle to make sure it was warm. The shop claimed they took it for a test drive but I'm having my doubts. This was my first trip out after getting it back from them.

Is there a way to easily test the jet pump to see if that is the problem?

Thanks again for all of the help.

Could this be something as simple as a fouled spark plug from running too much oil for the break in?

Yes and very cheap to check.

Typical Shop.
Make sure your rave solenoid is connected and check it for operation. 5K RPM is power valve territory. Pull the caps of the raves and make sure they are free. Disconnect the hose from the rave solenoid and with a puff of air in hour cheeks blow and suck back....both raves should lift and bottom. There is a long tube that comes from the engine crankcase and connects to the rave solenoid. That tube has a check valve near the crank case. That valve should hold pressure one way. You should not be able to blow air into the tube and into the crankcase.

You can also check to insure the raves are assembled properly. Good Luck !!

Thank you for the comments. I took it back to the shop and he thinks it's just a fouled spark plug but is going to check it out. I'll let you all know what happens.
