Hello, my name is***** will assist you.
The exhaust on the ski is water cooled. when the ski is running, normally there is enough combustion pressure in the exhaust to keep the water out of the cylinders. When you started the water before the ski, you filled the cylinders with water through the exhaust valves. When the engine hydro locked, it could have bent a valve or two and now, there is nothing to stop the water from entering the cylinders. You are going to need to do both a compression test and a leakdown test on the engine. Just to see if the cylinders can make and then hold pressure. If they cannot, you will need to rebuild the upper end of the engine.
