1992 SP Engine does not turn

Hi I just bought a very clean 1992 Seadoo xp with a stuck engine or jet drive. I know it has been sitting for along time and the guy I got it from said it was the jet drive. I am new to working on waverunners and was wondering if someone could point me in the right direction for separating the engine from the drive shaft to see if the engine is good.

There are only two ways to accomplish this. Pull the engine, or pull the jet pump.
Actually, you can remove the engine mount bolts and slide it forward also, but you will have to disconnect the exhaust also.

So I made a puller out of a 2x4, yes wood. It worked great. Man that pump was glued on there. It is off and the plastic wear ring is all messed up but I can figure that out I believe...

BUT IT GETS BETTER...After pulling the jet pump and the long shaft out I pulled the spark plugs and turned the engine by hand at the flywheel. It felt very very good until I rotated it alittle further and it locked. I turned it the opposite way and the same thing, 1/2 rotation and locked almost like something was in the engine. Odd. It was about to get worse. Upon putting the plugs back in and trying to rotate it again the whole cylinder assembly lifted off from the bottom end. WHAT THE... someone has been in here. Looks like they tore the engine down thinking the problem was the engine but it was actually the jet drive. There was a small allen head bolt in the engine. Cylinders lifted up because the bolts had been loosened but I would have never noticed that because the head was put back on.

So the cylinder bores are very good still at standard 76mm. I will hone them out because there is slight rust in one spot. The pistons are scuffed so since I'm doing all this work I will replace them and obviously all of the gaskets and o rings. When I pulled the cylinder all of the water and junk that was in there went into the rear cylinder crank area so I'm going to pull that and turn it upside down, flush, and oil the heck out of it.

I am going to try and get the jet drive apart and get some pictures on here.
