2004 Gtx 4-tec partially seized mystery! :/
As some of you guys know my Seadoo all of a sudderrn partially seized up.
I removed the jet pump : FREE
I removed super charger : FREE
i went to the back of the ski to try and turn the engine over by hand with spark plugs removed and it felt seized solid! My mate even snapped a 12mm Allen socket as it was that tight!
Now I've went to remove the engine today, all I done since we last tried to turn it over was drain the coolent, removed inlet manifold and some hoses. We got stuck trying to remove the drive shaft as we could not pull the collar back to revel the C-clip so before we pushed it back into the garage my mate went to see how tight it was at turning over for some reason, only to find it felt free!!!!! EH!
so I insisted that we put the supercharger back on and try turning it over via the superchargr nut as before it would not turn over and only the clutch would slip on the sc. But again it was free and the engine was now turning over via the supercharger nut!
Any Ideas why this has happened? I'm still going to remover the engine as I want to get to the root of the problem before it goes back together.
Could the carbon ring or something in that aera cause it to bind? Just as we only found out it seemed free again after trying to pull the collar back. :/ mystery.

Feck knows mate, can that happen. I still need to take the drive shaft out and then the engine. How would I check that dude,

Its the bearing in the end of the PTO coupler. That's the only thing left not internal to the motor. Slide the shaft out and have a look at that bearing. Be careful as you remove the shaft not to pull the bearing out of the rubber coupling. They never seal right after the bearing comes out and then you have an oil leak.
And, if I were you, I would keep everything in one thread. 6 threads on the same issue is confusing and people will suggest you do things you already have.
Saw your supra on the Facebook page. Saweeeet.

If the PTO bearing was seized it would have destroyed the bellow. I'm willing to bet it's something in the rotating assembly that's seized, maybe a bad bearing or thrust on the crank
