I recently purchased a 98 GXTL. When I bought it the owner said he previously had it out in the begining of the year and when he went to sell it, it wouldn't start. So after buying it I removed the plugs and water shot out with oil so I completely emptied all the water out and removed the water/oil from the crankcase. I added new oil and cleaned the plugs reassembled and it started right up. After starting it and shutting it off I figured I was good to go. Attached the hose to the rear started right up but then Stallled and I figured it was still getting rid of some of the water started again then stalled cut the water immediately removed the plugs and water was shooting out again same in the crank case removed al water again and added oil to the crank and cylinders to prevent from rusting and seizing. What do you think it is ? Head gasket or something or is ther maybe a tube crossed? Please help. This is my first PWC but I am mechanically so if I he to tear down let me know what you's think. Thank you
