Oil/Water sludge from exaust Please Help!!!

[Sportster1995]

I have a 1995 Seadoo Sportster, I bought it used and have only taken it out once. The time I took it out I ran great with no problems. About 3 months later I was getting ready to take it out again and when I started it up it started spitting a sludgy mixture of oil and water out the exaust. I am wondering if I might have flushed the engine wrong, or if there might be a more serious problem. Any help would be great, Thankyou

If it continues to spit oil out of the exhaust in the future, then the crankshaft seals are leaking oil into the engine cases and you will need a rebuilt crankshaft. But if it stops leaking, you are just blowing the water out of the muffler, which you should be doing each time you finish using it for the day.
