Loss of power and overheating

2002 GTX DI

Hi, I was on the lake today running full speed when suddenly I lost 80 to 90 percent of my thrust. After checking for something in the intake housing and limping along the engine temp alarm went off and I noticed no water pumping out the side. I pulled it up on the beach at the house and rolled it on its side and saw nothing in the intake or the thrust tube. Do jet ski impellers have a rubber hub on them like outboard props do? Can anybody suggest anything? Before I drop the jet pump assembly.

I am new to the sea doo world, So thanks for any help.

Got back into the rear housing with a flash light, and it looks like a piece of rubber has torn away from something, or i sucked up a piece of something.

 

[jhdarby]

Any thoughts on what that might be, if it came from the boat?

 

[custompartsguy]

picture of it?

 

[jhdarby]

I cant get a picture of it yet. I will tear it down tomorrow

 

[custompartsguy]

are you talking about your pump, there is a piece of rubber stuck in your pump?

 

[jhdarby]

Aft of the impeller, but forward of the imp cone or cover

 

[custompartsguy]

so it was stuck in your pump housing then?

 

[jhdarby]

Yes something is stuck in the housing....... is it something i sucked in, or is it part of the seal and wear ring? I am new to this jet pump thing I would apreciate a look at a few pics

Thanks Hank

It looks to me like I sucked the wear ring inside out. Is the wear ring the white hard bacolite material, that is broken, or the hard black plastic stuck in my impeller? I got the impeller off . To me it looks like the wear ring might be both the white plastic and the black plastic........ any thoughts?

 

[Chris_cox]

correct it is made of 2 materials, the white part rest against the housing the black faces in towards the impeller

 

[jhdarby]

Do they often implode on the impeller?

 

[Chris_cox]

if something goes in and messes it up, it can happen

 

[jhdarby]

Thank You .....Custompartsguy and Chris for your help.......Looking up the price and availability of wear ring, and maybe new impeller.

[custompartsguy]

yeah your impeller does show some wear on it, but I do not know if it is enough to affect it.

 

[jhdarby]

what would have torn my wear ring up then........... just 7 years of wear?????????????????

 

[ski-d00]

yes, 7 years of wear will do it. not a fan of the 2 piece wear rings, they all seem to separate sooner or later like yours did. there are aftermarket ones that are 1 solid pc of delrin and they are cheaper than the OEMs and just wear down instead of getting chewed up into pcs.

 

[custompartsguy]

great job with the pictures, pics are worth 1000 words
