Would you use this impeller? *pics*

[00SLX]

I am new to PWC and bought a 2000 SLX 1200 to fix up. I want to get it on the water for a test run before I invest more repair money, but am not sure if I should use this impeller and stator. It looked like a grape sized rock when through it a few times so I straightened it as best I could. Is there a chance I could damage the engine if I use it for a test run? Would you use it?

Thanks

What do you want to test?

Engine power?

Have you checked engine compression?

Have the carburetors been serviced/rebuilt?

What condition are the bearings in the stator? Any grinding or shaft looseness?

You might be able to get away the the impeller, but no way on the stator. That thing is going too cavitate like crazy, and could reduce cooling to the engine.

It had no spark when I bought it, and with your help (and others in this forum) I was able to get it running (bad CDI). It runs a little rough, but I think I need to get it on the water to really see how it runs. Compression is 120lbs, haven't cleaned carbs yet, need to replace tempo fuel / oil lines and repair some hull damage.

Bearings seem pretty good.

Thanks, I wondered about cavitation but did not realize that could cause overheating.

Well, you really want to get the fuel system, including the carburetors, cleaned up and in top condition before you venture out on the water.

Carbs don't clean themselves, and the rough running will probably go away once you have the fuel system cleaned up.

Running with dirty carbs or other fuel system problems runs the risk of damaging the engine through lean burn.

If the engine is mechanically in good condition (engine bearings turn smoothly, crank seals are not leaking badly, reeds are not damaged) then it should run just fine once you attend to the other things.

Don't run it to see what is wrong. Fix what you already know is wrong first.

Then test it, carefully.

While you are working on the other stuff, keep an eye out for an inexpensive replacement pump stator.

If you later on decide to part out the ski rather than keep it, you can probably re-sell the replacement stator for close to what you paid for it.

Sounds good, thanks.
I had found a really good post on how to change the tempo fuel lines, but can't seem to find it again. Any links to some good info would be really appreciated, thanks.
