Big Problem At The Lake Today (boom)
I went to the lake this morning for a quick test run, after installing the RE Blockoffs and had adjusted my throttle. I made a few passes and all seemed to be ok. After about 15 minutes of riding around, I took a five minute break on the trailer and then pulled back out for another spin.
HERE IS WHAT HAPPENED !!
I was cruising at around 30mph or so and then I hit the gas, thats when I heard a noise and the ski started to bog out. I let off and watched the rpms go down until it shut off. I immediately pulled the seat back and sall some smoke coming from underneath the seat. I could also here the water coming in and the hull was starting to sink from the back. I managed to drag it to the shore and held it up from sinking. Thanks to Frank (RXP6) for being there aswell tuning a ski. He was able to give me a hand. After getting the ski back to the trailer we pulled it out of the water and the water level in the hull was passed the SC inlet. I pulled the drain plugs and thats when we noticed the waterbox had blown apart.
I immediately went home and pulled just about everything I could think of off of the ski
Waterbox and Jpipe.
When I pulled the spark plugs off I could see water in the cylinders. I tried cranking the motor to get the water out. Some water came out, but it didnt seem to have really good cranking power. After that I kept on draining more oil, and thats when the milky oil started to come out. Before I cranked the engine, the oil looked pretty normal. it had water but was not milky looking.
What can I do ? to make sure all the water is out ? I scared that I might have bent valves or something

You need to pull it apart. Before you do se a dial indicator to see if the rods are bent. It will tell you if they are bent just a bit that you could not see with your eye. We had the same thing happen to another ski. Got the water out, it ran for a while and then threw a rod out of the bolck. Ouch. Better to be safe than sorry. I would check out the whole motor. Water does not like to compress.

Try to get it to start and run... Idle only/ compression check etc.

did you have a modded box, a green box, or just a stock box on it when it blew?
