Yesterday i was snowmobiling with some friends on a lake, and we entered a channel with unsafe ice. I did not know the ice wasent safe because the ice at all other parts of the lake is like a couple feet deep. So i stopped, the ice cracked, and the snowmobile went in. It was about 6 feet deep where the sled sunk, and we had to have alot of people help to pull it out. now i am in the proccess of evacuating all the water in my engine for water. We have already pulled the cylinders apart, the airbox off, the exuast pipe off, and replaced the spark plugs. The sled starts but it bogs down if you try to give it gas. How can i fix this and what else do i need to drain to make it run properly. Any advice would be GREATLY appreciated.I will be posting pics at a later time.
