I'm sure water didn't get high enough to enter the cylinders. I do know it is in the oil though. I pumped all the water I could out of the boat but there is still a large amount of ice in there. I'll have to put a heater in there to melt it. I am in eastern Canada - still cold here. What about the transmission? I assume oil could have entered this oil too? Maybe I'll get a small outboard this year. I wonder if insurance would cover this damage?
