I just got a 95 seadoo spx that was hydrolocked. Pulled plugs and it turns over easily and yes water shot out. The previous owner never winterized it. I pulled the heads and they look good along with the cylinders, no rust, or cracks. The exhaust pipe was full of water also. I'm not familar with this engine can this water get into the crankcase and is their anyway to check crankcase oil without pulling the cylinders off?

That's a 2 stroke...it doesn't have crankcase oil it relies on the injector oil in the fuel to lube the crank. I would get the water out and do a compression test to see what's going on inside.
Here is some information on a compression test;
To test compression, remove both spark plugs. Place spark plug caps on the plug cap studs near the cylinder head to ground the empty caps. This completes the circuit of the ignition electrical system and prevents any electrical problems from the caps being un grounded. Using the correct adapter for the threaded end of the tester,( same length of the spark plug threads length)screw in the tester in one plug hole. Hold the throttle wide open. Push the start button. Watch the compression guage, when it peaks out at the most compression, let go the start button. Read the psi number. I would do it 3 times to be sure it is accurate. Check both cylinders the same way. The ideal compression is 150 psi per cylinder. If it is less, it's not a problem as long as they are close to being the same. If the psi is less than 90 it might need be time for a tear down and a rebuild. If the psi in 1 cylinder is say 140 psi and the other is 80 psi you need to tear down and repair. This difference is a lot then there is a problem. I hope this helps you.

It's a 2 stroke....the fuel goes into the crank area then into the top end, gets fired and out the exhaust...in 2 strokes. If you keep turning the engine it will spit it out the plug holes.
