Blaes

I'm a newbie to this forum and checked some posts after my son swamped my Jet Ski (97 1100 ZXI). Got all the water out and the engine running, but it will NOT idle. It shuts down under a rough idle, or any less than 2500 RPM.

Noticed that only the front cylinder gets very hot after running for 15 minutes with cooling hooked to garden hose. I have two theories:

1. Cooling system blocked to front cylinder
2. Extreme friction in front cylinder causing overheating, due to ???, I'm afraid to ask and probably expect an engine re-build but so far, I ruled out a bent rod.

Any suggestions from someone experienced?

Thanks
