I got a bone stock 2006 SXR that I cant get to to piss out the side and it ends up overheating. The ski has sat for about 2 years now and was stored in a shed that caught fire. The ski does not appear to be damaged but it's possible the firemen could have sprayed the ski down with their high pressure hoses (maybe they sprayed up the pump and screwed something up?). I have taken all the cooling lines I can find off and blown compressed air through them and the seem to be clear. Any thoughts? Thanks.
SXR SXR not cooling. Need help.

Did you blow air through the through hull cooling lines. I've had a problem with a 750 that sat and wasn't flushed out and salt built up in the cooling passages in the exhaust manifold

If you're sure , that it's at the pump, you might have to take the pump out and tak a look if you got something lodged in the intake hole. But, like he said, try the air a few times, stick it in the pisser and blow it out. Do you have a back flush ?
Have not tried a back flush yet. To check the head gasket should i just start the ski and feel around where the gasket is to see if its leaking pressure? Also, I'm almost positive it ran just fine off the garden hose and not did overheat. But that was a year ago. Thanks for the advise.

My sxr did this once, it had sand in the cooling line at the pump. Put the hose on the flush out and crank it up, should flow out the pisser and the pump. Make sure water is coming out of both. If this doesn't work check the elbows on the head and make sure there are not any small rocks trapped there(happened on my BOB)

What's the update? Did you figure it out?

Yep. That'll stop the cooling.

That's the exact problem I had.

Shouldn't be necessary. Backflush, if that doesn't do it, Blow out all the lines with an air compressor. Should take care of ANY blockage. If that doesn't fix it, it is your head gasket 99% of the time. Last it could be a small pebble really jammed in a 90 degree fitting.
Here is update after getting the ski out this past weekend. All the cooling lines seem to be clear. I could blow air through all of them and suck water through the one connected to the pump. So I guess this means the head gasket is blown? I alway thought the pressure for the cooling system came from the pump until this weekend when I disconnected the line that runs off the pump and no water was shooting out even with the ski running. Where does the pressure come from for the cooling system? Thanks.

Which line did you remove on the pump? Did you happen to remove the one from the reduction nozzle?
I took the one off that's easier to get to (the higher of the two I think). There is another one that I think goes to the exhaust manifold or somewhere else under the engine. That one i did not take off. This really puzzles me. I basically took my 04 superjet completely apart and put it back together but cant figure this out.

The one that goes to your exhaust manifold is the water input to the engine.

Also remember that a stock sxr has two water cooling overboard outlets. One on the side of the hull and one that dumps by the pump

Ok. you disconnected the other spitter. One spits into the pump, one goes overboard. You need to Disconnect the one that goes into your pipe....Put it in the lake and fire it up. If that one is spitting water when it is running and in the water, blown head gasket.....if not, you have a rock in the 90 at the pump.
